mips o32: fix build

Commit 917c2ccf3a "Refactor stack pointers" moved mips_REG_* macros
from linux/mips/arch_regs.h to linux/mips/arch_regs.c because these
macros are no longer used outside syscall.c or files included by
syscall.c, but this caused a build regression on mips o32 because
decode_syscall_subcall() uses mips_REG_SP prior to its definition.

* syscall.c (decode_syscall_subcall): Move ...
* linux/mips/get_syscall_args.c: ... here.
* NEWS: Mention this fix.

Fixes: v4.26~61 "Refactor stack pointers"

+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 2.1, February 1999
+
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+as the successor of the GNU Library Public License, version 2, hence
+the version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom
+to share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too,
+but we suggest you first think carefully about whether this license or
+the ordinary General Public License is the better strategy to use in
+any particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get it
+if you want it; that you can change the software and use pieces of it in
+new free programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide complete
+object files to the recipients, so that they can relink them with the
+library after making changes to the library and recompiling it. And you
+must show them these terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there
+is no warranty for the free library. Also, if the library is modified
+by someone else and passed on, the recipients should know that what they
+have is not the original version, so that the original author's reputation
+will not be affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license
+obtained for a version of the library must be consistent with the full
+freedom of use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License. This license, the GNU Lesser General
+Public License, applies to certain designated libraries, and is quite
+different from the ordinary General Public License. We use this license
+for certain libraries in order to permit linking those libraries into
+non-free programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination
+fits its criteria of freedom. The Lesser General Public License permits
+more lax criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a
+de-facto standard. To achieve this, non-free programs must be allowed
+to use the library. A more frequent case is that a free library does
+the same job as widely used non-free libraries. In this case, there
+is little to gain by limiting the free library to free software only,
+so we use the Lesser General Public License.
+
+In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system,
+as well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is linked
+with the Library has the freedom and the wherewithal to run that program
+using a modified version of the Library.
+
+The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+   0. This License Agreement applies to any software library or other
+   program which contains a notice placed by the copyright holder or
+   other authorized party saying it may be distributed under the terms of
+   this Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work
+   which has been distributed under these terms. A "work based on
+   the Library" means either the Library or any derivative work under
+   copyright law: that is to say, a work containing the Library or a
+   portion of it, either verbatim or with modifications and/or translated
+   straightforwardly into another language. (Hereinafter, translation
+   is included without limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for
+   making modifications to it. For a library, complete source code
+   means all the source code for all modules it contains, plus any
+   associated interface definition files, plus the scripts used to
+   control compilation and installation of the library.
+
+   Activities other than copying, distribution and modification are not
+   covered by this License; they are outside its scope. The act of running
+   a program using the Library is not restricted, and output from such
+   a program is covered only if its contents constitute a work based
+   on the Library (independent of the use of the Library in a tool for
+   writing it). Whether that is true depends on what the Library does
+   and what the program that uses the Library does.
+
+   1. You may copy and distribute verbatim copies of the Library's
+   complete source code as you receive it, in any medium, provided
+   that you conspicuously and appropriately publish on each copy an
+   appropriate copyright notice and disclaimer of warranty; keep intact
+   all the notices that refer to this License and to the absence of any
+   warranty; and distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+   2. You may modify your copy or copies of the Library or any portion of
+   it, thus forming a work based on the Library, and copy and distribute
+   such modifications or work under the terms of Section 1 above,
+   provided that you also meet all of these conditions:
+
+      a) The modified work must itself be a software library.
+
+      b) You must cause the files modified to carry prominent notices
+      stating that you changed the files and the date of any change.
+
+      c) You must cause the whole of the work to be licensed at no charge
+      to all third parties under the terms of this License.
+
+      d) If a facility in the modified Library refers to a function or a
+      table of data to be supplied by an application program that uses
+      the facility, other than as an argument passed when the facility
+      is invoked, then you must make a good faith effort to ensure that,
+      in the event an application does not supply such function or table,
+      the facility still operates, and performs whatever part of its
+      purpose remains meaningful.
+
+   (For example, a function in a library to compute square roots
+   has a purpose that is entirely well-defined independent of
+   the application. Therefore, Subsection 2d requires that any
+   application-supplied function or table used by this function must
+   be optional: if the application does not supply it, the square root
+   function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library,
+   and can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work
+   based on the Library, the distribution of the whole must be on the
+   terms of this License, whose permissions for other licensees extend
+   to the entire whole, and thus to each and every part regardless of
+   who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is
+   to exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume
+   of a storage or distribution medium does not bring the other work
+   under the scope of this License.
+
+   3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To
+   do this, you must alter all the notices that refer to this License,
+   so that they refer to the ordinary GNU General Public License,
+   version 2, instead of to this License. (If a newer version than
+   version 2 of the ordinary GNU General Public License has appeared,
+   then you can specify that version instead if you wish.) Do not make
+   any other change in these notices.
+
+   Once this change is made in a given copy, it is irreversible for
+   that copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+   4. You may copy and distribute the Library (or a portion or derivative
+   of it, under Section 2) in object code or executable form under the
+   terms of Sections 1 and 2 above provided that you accompany it with
+   the complete corresponding machine-readable source code, which must
+   be distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from
+   a designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+   5. A program that contains no derivative of any portion of the Library,
+   but is designed to work with the Library by being compiled or linked
+   with it, is called a "work that uses the Library". Such a work, in
+   isolation, is not a derivative work of the Library, and therefore
+   falls outside the scope of this License.
+
+   However, linking a "work that uses the Library" with the Library
+   creates an executable that is a derivative of the Library (because it
+   contains portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section
+   6 states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header
+   file that is part of the Library, the object code for the work may
+   be a derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can
+   be linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions
+   (ten lines or less in length), then the use of the object file
+   is unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+   6. As an exception to the Sections above, you may also combine or link
+   a "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under
+   terms of your choice, provided that the terms permit modification
+   of the work for the customer's own use and reverse engineering for
+   debugging such modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered
+   by this License. You must supply a copy of this License. If the work
+   during execution displays copyright notices, you must include the
+   copyright notice for the Library among them, as well as a reference
+   directing the user to the copy of this License. Also, you must do
+   one of these things:
+
+      a) Accompany the work with the complete corresponding
+      machine-readable source code for the Library including whatever
+      changes were used in the work (which must be distributed under
+      Sections 1 and 2 above); and, if the work is an executable linked
+      with the Library, with the complete machine-readable "work that
+      uses the Library", as object code and/or source code, so that the
+      user can modify the Library and then relink to produce a modified
+      executable containing the modified Library. (It is understood
+      that the user who changes the contents of definitions files in the
+      Library will not necessarily be able to recompile the application
+      to use the modified definitions.)
+
+      b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a
+      copy of the library already present on the user's computer system,
+      rather than copying library functions into the executable, and
+      (2) will operate properly with a modified version of the library,
+      if the user installs one, as long as the modified version is
+      interface-compatible with the version that the work was made with.
+
+      c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+      d) If distribution of the work is made by offering access to copy
+      from a designated place, offer equivalent access to copy the above
+      specified materials from the same place.
+
+      e) Verify that the user has already received a copy of these
+      materials or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the
+   Library" must include any data and utility programs needed for
+   reproducing the executable from it. However, as a special exception,
+   the materials to be distributed need not include anything that is
+   normally distributed (in either source or binary form) with the major
+   components (compiler, kernel, and so on) of the operating system on
+   which the executable runs, unless that component itself accompanies
+   the executable.
+
+   It may happen that this requirement contradicts the license
+   restrictions of other proprietary libraries that do not normally
+   accompany the operating system. Such a contradiction means you
+   cannot use both them and the Library together in an executable that
+   you distribute.
+
+   7. You may place library facilities that are a work based on the
+   Library side-by-side in a single library together with other library
+   facilities not covered by this License, and distribute such a combined
+   library, provided that the separate distribution of the work based on
+   the Library and of the other library facilities is otherwise permitted,
+   and provided that you do these two things:
+
+      a) Accompany the combined library with a copy of the same work based
+      on the Library, uncombined with any other library facilities. This
+      must be distributed under the terms of the Sections above.
+
+      b) Give prominent notice with the combined library of the fact
+      that part of it is a work based on the Library, and explaining
+      where to find the accompanying uncombined form of the same work.
+
+   8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under
+   this License. However, parties who have received copies, or rights,
+   from you under this License will not have their licenses terminated
+   so long as such parties remain in full compliance.
+
+   9. You are not required to accept this License, since you have not
+   signed it. However, nothing else grants you permission to modify
+   or distribute the Library or its derivative works. These actions
+   are prohibited by law if you do not accept this License. Therefore,
+   by modifying or distributing the Library (or any work based on the
+   Library), you indicate your acceptance of this License to do so, and
+   all its terms and conditions for copying, distributing or modifying
+   the Library or works based on it.
+
+   10. Each time you redistribute the Library (or any work based on
+   the Library), the recipient automatically receives a license from
+   the original licensor to copy, distribute, link with or modify the
+   Library subject to these terms and conditions. You may not impose
+   any further restrictions on the recipients' exercise of the rights
+   granted herein. You are not responsible for enforcing compliance by
+   third parties with this License.
+
+   11. If, as a consequence of a court judgment or allegation of patent
+   infringement or for any other reason (not limited to patent issues),
+   conditions are imposed on you (whether by court order, agreement
+   or otherwise) that contradict the conditions of this License, they
+   do not excuse you from the conditions of this License. If you cannot
+   distribute so as to satisfy simultaneously your obligations under this
+   License and any other pertinent obligations, then as a consequence
+   you may not distribute the Library at all. For example, if a patent
+   license would not permit royalty-free redistribution of the Library
+   by all those who receive copies directly or indirectly through you,
+   then the only way you could satisfy both it and this License would
+   be to refrain entirely from distribution of the Library.
+
+   If any portion of this section is held invalid or unenforceable under
+   any particular circumstance, the balance of the section is intended
+   to apply, and the section as a whole is intended to apply in other
+   circumstances.
+
+   It is not the purpose of this section to induce you to infringe any
+   patents or other property right claims or to contest validity of
+   any such claims; this section has the sole purpose of protecting
+   the integrity of the free software distribution system which
+   is implemented by public license practices. Many people have made
+   generous contributions to the wide range of software distributed
+   through that system in reliance on consistent application of that
+   system; it is up to the author/donor to decide if he or she is willing
+   to distribute software through any other system and a licensee cannot
+   impose that choice.
+
+   This section is intended to make thoroughly clear what is believed
+   to be a consequence of the rest of this License.
+
+   12. If the distribution and/or use of the Library is restricted in
+   certain countries either by patents or by copyrighted interfaces, the
+   original copyright holder who places the Library under this License
+   may add an explicit geographical distribution limitation excluding
+   those countries, so that distribution is permitted only in or among
+   countries not thus excluded. In such case, this License incorporates
+   the limitation as if written in the body of this License.
+
+   13. The Free Software Foundation may publish revised and/or new
+   versions of the Lesser General Public License from time to time. Such
+   new versions will be similar in spirit to the present version, but
+   may differ in detail to address new problems or concerns.
+
+   Each version is given a distinguishing version number. If the Library
+   specifies a version number of this License which applies to it and
+   "any later version", you have the option of following the terms and
+   conditions either of that version or of any later version published
+   by the Free Software Foundation. If the Library does not specify a
+   license version number, you may choose any version ever published by
+   the Free Software Foundation.
+
+   14. If you wish to incorporate parts of the Library into other free
+   programs whose distribution conditions are incompatible with these,
+   write to the author to ask for permission. For software which is
+   copyrighted by the Free Software Foundation, write to the Free Software
+   Foundation; we sometimes make exceptions for this. Our decision will
+   be guided by the two goals of preserving the free status of all
+   derivatives of our free software and of promoting the sharing and
+   reuse of software generally.
+
+   NO WARRANTY
+
+   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+   WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE

+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of
+the ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+<one line to give the library's name and an idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published
+by the Free Software Foundation; either version 2.1 of the License, or
+(at your option) any later version.
+
+This library is distributed in the hope that it will be useful, but
+WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY
+or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public
+License for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or
+your school, if any, to sign a "copyright disclaimer" for the library,
+if necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+This information applies to bundles automatically generated
+by github and gitlab.
+
+strace's program version is maintained using git-version-gen script, therefore,
+building strace depends on "git describe" (a full git clone is needed for this)
+or, alternatively, a .tarball-version file.  Neither github nor gitlab can
+provide the latter, they also do not allow to inject a .tarball-version file

 This is [strace](https://strace.io) -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux.  It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state.  The operation of strace is made possible by the kernel feature known as [ptrace](http://man7.org/linux/man-pages/man2/ptrace.2.html).

+
+ - Sane POSIX shell.
+ - gcc-like compiler that supports C99 and some GNU extensions (namely, empty
+   structures, empty definitions, zero length arrays, ranged designated
+   initialisers).
+ - libc. GNU libc and musl are supported.
+ - Linux UAPI headers.
+ - GNU Make.
+ - GNU coreutils.
+ - For running test suite: gawk, grep, sed, runtime environment for all
+   personalities.
+ - Requirements for optional features are documented in their description.
+
+1. CONFIGURATION AND OPTIONAL FEATURES
+
+Configuration is done using GNU Autoconf-generated configure script.
+Please refer to the README-configure file for generic information regarding
+configure usage.
+
+In addition to standard configure options, strace's configure file provides
+the following options:
+
+1.1. Additional build and testing hardening
+
+  --enable-gcc-Werror     turn on gcc's -Werror option
+  --enable-code-coverage  Whether to enable code coverage support
+  --with-gcov=GCOV        use given GCOV for coverage (GCOV=gcov).
+  --enable-valgrind       Whether to enable Valgrind on the unit tests
+  --disable-valgrind-memcheck
+                          Whether to skip memcheck during the Valgrind tests
+  --disable-valgrind-helgrind
+                          Whether to skip helgrind during the Valgrind tests
+  --disable-valgrind-drd  Whether to skip drd during the Valgrind tests
+  --enable-valgrind-sgcheck
+                          Whether to use sgcheck during the Valgrind tests
+
+1.2. Optional features
+
+1.2.1. Multiple personalities support
+
+  --enable-mpers=yes|no|check|m32|mx32
+                          whether to enable multiple personalities support
+                          required for proper decoding of structures used by
+                          tracees with personalities that differ from the
+                          personality of strace, default is yes.
+
+Personality is a way system call is performed (in terms of ABI). For example,
+Linux kernel on multiple 64-bit architectures that evolve from their 32-bit
+counterparts have support for running 32-bit binaries with 32-bit system call
+ABI, and that system call ABI constitutes a separate personality in strace's
+terms. Another example is 32-on-64 bit ABI; while exploiting the same way for
+performing system calls as native 64-bit system calls, this ABI has different
+type sizes and, as a result, also constitutes a separate personality; the only
+such ABI that is currently supported by strace is x32 on x86_64. This is
+important as different ABIs use different alignments and type sizes, as a
+result, fields in structures in unions have different offsets on different
+ABIs. In order to be able to correctly parse all the structures used in various
+system calls and ioctl commands, strace compiles these structure definitions
+for these different ABI and then parses DWARF of these compiled definitions in
+order to generate proper structure definitions that compiled with decoder code.
+Taking the aforementioned into account, there are the following requirements:
+
+ - gawk (at least version 3)
+ - Ability to compile for m32 personality (on architectures where it is supported)
+  - On x86_64, x32, powerpc64, sparc64, riscv64, tile64: gcc -m32
+  - s390x: gcc -m31
+  - AArch64: a separate compiler for armv7 EABI
+   - See information about configuration in "1.3.2. AArch64: AArch32 support"
+ - Ability to compile for mx32 personality (on architectures where it is supported)
+  - On x86_64: gcc -mx32
+ - For tests: runtime support (linker, libc, and loader)
+
+1.2.2. Stack unwinding (-k option)
+
+  --with-libunwind        use libunwind to implement stack tracing support
+  --with-libiberty        use libiberty to demangle symbols in stack trace
+
+1.3. Architecture-specific features
+
+1.3.1. ARMv7: OABI support
+
+  --enable-arm-oabi       enable OABI support on ARM EABI
+
+1.3.2. AArch64: AArch32 support
+
+  CC_FOR_M32
+  CPP_FOR_M32
+  CFLAGS_FOR_M32
+  CPPFLAGS_FOR_M32
+
