2016-03-19add copy_file_range syscall numbers from linux v4.5Szabolcs Nagy-0/+2
it was introduced for offloading copying between regular files in linux commit 29732938a6289a15e907da234d6692a2ead71855 (microblaze and sh does not yet have the syscall number.)
2016-03-19mips64: add recent linux syscall numbersSzabolcs Nagy-0/+6
add userfaultfd, membarrier and mlock2 system call numbers.
2016-03-18deduplicate bits/mman.hSzabolcs Nagy-45/+11
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.
2016-03-11correct pointer types for a_ll_p and a_sc_p primitives on mips64Rich Felker-4/+4
these changes should not affect generated code, but they reflect that the underlying objects operated on by a_cas_p are supposed to have type volatile void *, not volatile long. in theory a compiler could treat the effective type mismatch in the "m" memory operands as undefined behavior.
2016-03-11make mips64 a_sc_p atomic primitive's asm constraints work with clangRich Felker-1/+1
apparently clang does not accept matching-register input and output constraints that differ in size (32-bit vs 64-bit). based on patch by Jaydeep Patil.
