2016-03-18deduplicate bits/mman.hSzabolcs Nagy1-59/+0
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.
2016-01-26add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flagsSzabolcs Nagy1-0/+1
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
2015-01-30move MREMAP_MAYMOVE and MREMAP_FIXED out of bitsTrutz Behn1-3/+0
the definitions are generic for all kernel archs. exposure of these macros now only occurs on the same feature test as for the function accepting them, which is believed to be more correct.
2013-01-12add missing mmap options and madvices to bits/mman.h based on linux headersSzabolcs Nagy1-0/+7
2012-12-06add more arch-specific MAP_ macros to bits/mman.hrofl0r1-0/+4
these are also needed by qemu.
2012-12-06add MAP_NORESERVE to bits/mman.hrofl0r1-0/+1
this is needed for qemu, and since it differs for each arch it can't be circumvented easily by using a macro in CFLAGS.
2012-05-22fix missing _BSD_SOURCE support in bits/*.hRich Felker1-1/+1
this is actually rather ugly, and would get even uglier if we ever want to support further feature test macros. at some point i may factor the bits headers into separate files for C base, POSIX base, and nonstandard extensions (the only distinctions that seem to matter now) and then the logic for which to include can go in the main header rather than being duplicated for each arch. the downside of this is that it would result in more files having to be opened during compilation, so as long as the ugliness does not grow, i'm inclined to leave it alone for now.
