Subject[PATCH -mm v4 2/4] compat: move compat_siginfo_t definition to asm/compat.h
Date
This is a preparatory patch for the introduction of NT_SIGINFO elf note.

Make the location of compat_siginfo_t uniform across eight architectures
which have it. Now it can be pulled in by including asm/compat.h
or linux/compat.h.

Most of the copies are verbatim. compat_uid[32]_t had to be replaced by
__compat_uid[32]_t. compat_uptr_t had to be moved up before compat_siginfo_t
in asm/compat.h on a several architectures (tile already had it moved up).
compat_sigval_t had to be relocated from linux/compat.h to asm/compat.h.
