2016-05-12	deduplicate __NR_* and SYS_* syscall number definitions	Bobby Bingham	-320/+0

2016-04-03	add support for mips and mips64 r6 isa	Rich Felker	-12/+24
	mips32r6 and mips64r6 are actually new isas at both the asm source and opcode levels (pre-r6 code cannot run on r6) and thus need to be treated as a new subarch. the following changes are made, some of which yield code generation improvements for non-r6 targets too: - add subarch logic in configure script and reloc.h files for dynamic linker name. - suppress use of .set mips2 asm directives (used to allow mips2 atomic instructions on baseline mips1 builds; the kernel has to emulate them on mips1) except when actually needed. they cause wrong instruction encodings on r6, and pessimize inlining on at least some compilers. - only hard-code sync instruction encoding on mips1. - use "ZC" constraint instead of "m" constraint for llsc memory operands on r6, where the ll/sc instructions no longer accept full 16-bit offsets. - only hard-code rdhwr instruction encoding with .word on targets (pre-r2) where it may need trap-and-emulate by the kernel. otherwise, just use the instruction mnemonic, and allow an arbitrary destination register to be used.
2016-03-19	add copy_file_range syscall numbers from linux v4.5	Szabolcs 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.)
2016-03-19	mips64: add recent linux syscall numbers	Szabolcs Nagy	-0/+6
	add userfaultfd, membarrier and mlock2 system call numbers.
2016-03-18	deduplicate bits/mman.h	Szabolcs 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.
2016-03-11	correct pointer types for a_ll_p and a_sc_p primitives on mips64	Rich 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.
2016-03-11	make mips64 a_sc_p atomic primitive's asm constraints work with clang	Rich 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.
2016-03-06	add mips64 port	Rich Felker	-0/+2171
	patch by Mahesh Bodapati and Jaydeep Patil of Imagination Technologies.
