bd8dd776db Add support for Altera's Nios-II softcore architecture
This commit adds strace support for Altera's Nios-II.  The architecture
is supported by Linux since v3.19, and it implements the generic syscall
ABI.

* configure.ac: Add nios2 support.
* cacheflush.c [NIOS2] (sys_cacheflush): New function.
* linux/nios2/*: New Nios-II specific files.
* Makefile.am (EXTRA_DIST): Add them.

a7c6e5143c Revert "Add support for Altera's Nios-II softcore architecture"
The patch originally submitted by Ezequiel García was OK, but I somehow
managed to mangle it so that most of the patch was not applied.

According to Ezequiel García, an architecture port based on the generic
syscall ABI is in progress.

This reverts commit 61e426e87ac81be4b4ff9de581635b4ea585624f.

61e426e87a Add support for Altera's Nios-II softcore architecture
This commit adds strace support for Altera's Nios-II official
kernel port as found in git://git.rocketboards.org/linux-socfpga.git

Notice that this an out-of-tree kernel architectural port, and uses the
legacy (non-generic) system call ABI. In particular, the port doesn't
support PTRACE_GETREGSET, so the implementation is based on PTRACE_GETREGS.

Given it's mandatory for new architectures to support the generic
syscall ABI and PTRACE_GETREGSET, if the nios2 architecure is ever
mainlined, the strace support will have to be re-factored accordingly.

* linux/nios2/ioctlent.h.in: New file.
* linux/nios2/syscallent.h: Likewise.
* Makefile.am (EXTRA_DIST): Add linux/nios2/ioctlent.h.in and
linux/nios2/syscallent.h.
* configure.ac: Add NIOS2 to the list of supported architectures.
* defs.h [NIOS2]: Use register reading system.
* process.c (struct_user_offsets): Add NIOS2 support.
* syscall.c (get_regs, get_scno, get_syscall_args,
get_syscall_result, get_error): Likewise.
* util.c (change_syscall): Likewise.
* mem.c (sys_getpagesize): Define on NIOS2.
* system.c [NIOS2] (sys_cacheflush, sys_nios2cmpxchg): New functions.
