Closes: https://github.com/strace/strace/issues/38
When <sys/reg.h> is included after <linux/ptrace.h>, the build fails
on m68k with the following diagnostics:
In file included from /usr/include/linux/ptrace.h:101:0,
from ptrace.h:51,
from sigreturn.c:2:
/usr/include/m68k-linux-gnu/sys/reg.h:26:3: error: expected identifier
before numeric constant
PT_D1 = 0,
^
Apparently, the only architecture where strace needs definitions
provided by <sys/reg.h> is x86_64, other three (m68k, tile, and x86)
are fine with definitions already provided by <linux/ptrace.h>.
Fix the issue by getting rid of <sys/reg.h> and defining necessary
macros in linux/x86_64/arch_regs.h file.
* configure.ac (AC_CHECK_HEADERS): Remove sys/reg.h.
* regs.h: Do not include <sys/reg.h>.
* linux/x86_64/arch_regs.h (R15, R14, R13, R12, RBP, RBX, R11, R10,
R9, R8, RAX, RCX, RDX, RSI, RDI, ORIG_RAX, RIP, CS, EFLAGS, RSP, SS,
FS_BASE, GS_BASE, DS, ES, FS, GS): New macros.
* NEWS: Mention this fix.
Fixes: v4.21~21 ("Include <sys/ptrace.h> early")
From the very first commit when CRIS architecture support was introduced
and up to this comment that ends the agony of this non-functional code,
this support was incomplete and could never be compiled.
* Makefile.am (EXTRA_DIST): Remove linux/crisv*.
* clone.c: Remove CRISV* checks.
* configure.ac ($host_cpu == cris*): Remove.
* linux/crisv10: Remove.
* linux/crisv32: Likewise.
Fixes: v4.5.18-77-gea0e6e8 ("CRIS support by Hinko Kocevar ...")
* configure.ac (AC_ARG_ENABLE([mpers])): Allow m32 and mx32 values
for --enable-mpers option.
* m4/mpers.m4 (st_MPERS): Check for personality support if personality
name is provided as an option. Fail if the requested personality
support is not available.

By very popular demand.
While we are here, let's refactor the condition for old_mmap_pgoff into

instead of AC_MSG_FAILURE when syscallent stubs cannot be generated.
On architectures supporting multiple personalities, multiple
personalities support in strace is required for proper decoding of
structures used by tracees with personalities that differ from the
personality of strace.
New configure options control whether multiple personalities support
in strace is mandatory, optional, or disabled.
The default is changed from what is now equivalent of
--enable-mpers=check (automatically detect whether required mpers
support could be enabled) to --enable-mpers (terminate the build
if required mpers support could not be enabled).
* configure.ac (AC_ARG_ENABLE([mpers])): New option.
* m4/mpers.m4 (st_MPERS): Use enable_mpers. Terminate the build
if mpers could not be enabled and enable_mpers==yes.
* strace.spec.in: Specify --enable-mpers=check to %configure.
* debian/rules (build/Makefile, build64/Makefile): Specify
--enable-mpers=check to configure.

* configure.ac: Use AC_CHECK_MEMBERS instead of st_CHECK_UNION_BPF_ATTR
for union bpf_attr field checks as the former seems to be enough
for the case.
* m4/st_bpf.m4: Remove.
* configure.ac: Check for union bpf_attr.test.duration.
* bpf.c (decode_BPF_PROG_TEST_RUN): New function.

command introduced by linux kernel commit v4.14-rc1~130^2~196^2~1.
* configure.ac: Check for numa_node member of union bpf_attr

When using linux kernel headers without commit v4.5-rc1~128^2~115^2~22
("netfilter: fix include files for compilation"), both <linux/ip.h>
and <linux/tcp.h> have to be included before <linux/netfilter/xt_osf.h>.
* configure.ac (AC_CHECK_HEADERS): Include <linux/ip.h>
and <linux/tcp.h> when checking for linux/netfilter/xt_osf.h header.
* tests/nfnetlink_osf.c: Include <linux/ip.h> and <linux/tcp.h>
before <linux/netfilter/xt_osf.h>.
I see it as a good idea to stick to system headers whenever possible
in order to also check for possible discrepancies between strace's
internal definitions and definitions present in the system headers.
* configure.ac (AC_CHECK_HEADERS): Add linux/kcmp.h.
* tests/kcmp.h [HAVE_LINUX_KCMP_H]: Include <linux/kcmp.h>,
do not define KCMP_FILE and KCMP_SYSVSEM.
