2016-03-19	add MADV_FREE madvise command from linux v4.5	Szabolcs Nagy	-0/+1
	allows the os to free the marked pages lazily on memory pressure. expected to increase malloc performance. new in linux commit 854e9ed09dedf0c19ac8640e91bcc74bc3f9e5c9
2016-03-18	deduplicate bits/mman.h	Szabolcs Nagy	-0/+59
	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.
2016-01-26	add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flags	Szabolcs Nagy	-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
2015-01-30	move MREMAP_MAYMOVE and MREMAP_FIXED out of bits	Trutz Behn	-0/+2
	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.
2014-01-07	fix signedness of pgoff argument to remap_file_pages	Rich Felker	-1/+1
	both the kernel and glibc agree that this argument is unsigned; the incorrect type ssize_t came from erroneous man pages.
2012-09-16	add clock_adjtime, remap_file_pages, and syncfs syscall wrappers	Rich Felker	-0/+5
	patch by Justin Cormack, with slight modification
2012-09-09	mincore syscall wrapper	Rich Felker	-0/+1

2012-09-07	default features: make musl usable without feature test macros	Rich Felker	-0/+2
	the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-06-04	_GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCE	Rich Felker	-1/+1
	this is ugly and stupid, but now that the *64 symbol names exist, a lot of broken GNU software detects them in configure, then either breaks during build due to missing off64_t definition, or attempts to compile without function declarations/prototypes. "fixing" it here is easier than telling everyone to add yet another feature test macro to their builds.
2012-05-22	support _BSD_SOURCE feature test macro	Rich Felker	-0/+3
	patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
2012-05-04	add 64 junk for sys/.h headers	Rich Felker	-0/+5

2011-03-03	namespace cleanup in sys/mman.h	Rich Felker	-1/+3

2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+37
