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.
Reported-by: Baruch Siach <baruch@tkos.co.il>
Fixes: v4.26~61 "Refactor stack pointers"
Commit 7488ce9e23 "Check whether PTRACE_GET_SYSCALL_INFO is supported
by the kernel" added a fork() call in test_ptrace_get_syscall_info()
which is included in the main strace executable code. Although the
test_ptrace_get_syscall_info() routine is not called on no-MMU targets,
the compiler can't optimize it out because it is a global symbol.
So build for no-MMU targets currently fails:
strace-ptrace_syscall_info.o: In function `test_ptrace_get_syscall_info':
ptrace_syscall_info.c:(.text+0x1c): undefined reference to `fork'
* ptrace_syscall_info.c (test_ptrace_get_syscall_info): Make
the definition depend on HAVE_FORK.
* strace.c (init): Call test_ptrace_get_syscall_info unconditionally.
* NEWS: Mention this fix.

The '/*' in the first line of the copyright header matches all files in
that directory. No other .gitignore file has this header. Drop it.
* linux/mips/.gitignore: Remove copyright header.

The sys_bpf(BPF_OBJ_GET_INFO_BY_FD, &bpf_prog_get_info_attr, ...) is
called in a loop. The bpf_prog_get_info_attr.info object is in size 104
but bpf_prog_get_info_attr.info_len is in size 168. Hence, if the prog
is jited, the second iteration onwards will have nr_jited_ksyms == 1
which is asking the kernel to fill the
bpf_prog_get_info_attr.info.jited_ksyms and it is NULL.
* tests/bpf-obj_get_info_by_fd.c (main): Clear memory beyond prog_info
at the start of every iteration.

This guarantees that map_info and prog_info objects are not accessed
out of bounds.
* tests/bpf-obj_get_info_by_fd.c: Include <string.h>.
(main): Use tail_alloc instead of calloc for map_info and prog_info.
Change strace-k.test to use chdir syscall instead of getpid syscall
because the latter is not universally available, e.g. there is no getpid
syscall on alpha.
* tests/stack-fcall-3.c (f3) <default>: Replace getpid with chdir.
* tests/strace-k.test: Likewise.
* tests/strace-k.expected: Likewise.
* tests/strace-k-demangle.expected: Likewise.
