- 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.
