[PATCH] compat: sigtimedwait
- Merge sys32_rt_sigtimedwait function in X86_64, IA64, PPC64, MIPS,
SPARC64, S390 32 bit layer into 1 compat_rt_sigtimedwait function. It will
also fix a bug of copy wrong information to 32 bit userspace siginfo
structure on X86_64, IA64 and SPARC64 when calling sigtimedwait on 32 bit
layer.
- Change all name the of siginfo_t32 structure in X86_64, IA64, MIPS,
SPARC64 and S390 to the name compat_siginfo_t as used in PPC64.
- Patch introduced a macro __COMPAT_ENDIAN_SWAP__ in
include/asm-mips/compat.h when MIPS kernel is compiled in little-endian
mode. This macro is used to do byte swapping in function
sigset_from_compat.
- This patch is only tested on X86_64 and IA_64.
