Currently arch_stack_wallk_reliable() is documented with an identical
comment in both x86 and S/390 implementations which is a bit redundant.
Move this to the header and convert to kerneldoc while we're at it.

Yes please, though there's a typo Peter pointed out in the commit log
above - should be walk not wallk. Let me know if you want me to resend
for that.

Currently arch_stack_wallk_reliable() is documented with an identical
comment in both x86 and S/390 implementations which is a bit redundant.
Move this to the header and convert to kerneldoc while we're at it.

Just a note. arch/powerpc/kernel/stacktrace.c has the same for
__save_stack_trace_tsk_reliable(), but it would not be nice to pollute
include/linux/stacktrace.h with that in my opinion. It is an old
infrastructure after all.
