add missing powerpc specific PROT_SAO memory protection flag this flag for strong access ordering was added in linux v2.6.27 commit aba46c5027cb59d98052231b36efcbbde9c77a1d 2016-01-24 00:20:43 +00:00			`#define PROT_SAO 0x10`

deduplicate bits/mman.h currently five targets use the same mman.h constants and the rest share most constants too, so move them to sys/mman.h before the bits/mman.h include where the differences can be corrected by redefinition of the macros. this fixes two minor bugs: POSIX_MADV_DONTNEED was wrong on most targets (it should be the same as MADV_DONTNEED), and sh defined the x86-only MAP_32BIT mmap flag. 2016-03-18 00:57:52 +00:00			`#undef MCL_CURRENT`
fix powerpc MCL_* mlockall flags in bits/mman.h the definitions didn't match the linux uapi headers. 2016-01-24 00:18:17 +00:00			`#define MCL_CURRENT 0x2000`

add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flags they lock faulted pages into memory (useful when a small part of a large mapped file needs efficient access), new in linux v4.4, commit b0f205c2a3082dd9081f9a94e50658c5fa906ff1 MLOCK_* is not in the POSIX reserved namespace for sys/mman.h 2016-01-24 01:19:38 +00:00			`#define MCL_ONFAULT 0x8000`
