2018-07-20	move inclusion of linux headers for kd.h, soundcard.h, vt.h to bits	midipix	-0/+3
	maintainer's note: while musl does not use the linux kernel headers, it does provide these three sys/* headers which do nothing but include the corresponding linux/* headers, since the sys/* versions are the ones documented for application use (and they arguably provide interfaces that are not linux-specific but common to other unices). these headers should probably not be provided by libc (rather by a separate package), but as long as they are, use the bits header framework as an aid to out-of-tree ports of musl for non-linux systems that want to implement them in some other way.
2018-07-17	add support for arch-specific ptrace command macros	Szabolcs Nagy	-0/+0
	sys/ptrace.h is target specific, use bits/ptrace.h to add target specific macro definitions. these macros are kept in the generic sys/ptrace.h even though some targets don't support them: PTRACE_GETREGS PTRACE_SETREGS PTRACE_GETFPREGS PTRACE_SETFPREGS PTRACE_GETFPXREGS PTRACE_SETFPXREGS so no macro definition got removed in this patch on any target. only s390x has a numerically conflicting macro definition (PTRACE_SINGLEBLOCK). the PT_ aliases follow glibc headers, otherwise the definitions come from linux uapi headers except ones that are skipped in glibc and there is no real kernel support (s390x PTRACE__AREA) or need special type definitions (mips PTRACE__WATCH_*) or only relevant for linux 2.4 compatibility (PTRACE_OLDSETOPTIONS).
2018-03-10	fix minor namespace issues in termios.h	Rich Felker	-0/+2
	the output delay features (NL, CR, TAB, BS, and VT) are XSI-shaded. VT is in the V* namespace reservation but the rest need to be suppressed in base POSIX namespace. unfortunately this change introduces feature test macro checks into another bits header. at some point these checks should be simplified by having features.h handle the "FTM X implies Y" relationships.
2017-11-05	ioctl TIOCGPTPEER from linux v4.13	Szabolcs Nagy	-0/+1
	added for safe opening of peer end of pty in a mount namespace. new in linux commit c6325179238f1d4683edbec53d8322575d76d7e2
2017-08-29	add SIOCGSTAMPNS socket ioctl macro to ioctl.h	Szabolcs Nagy	-0/+1
	it is defined in linux asm/sockios.h since commit ae40eb1ef30ab4120bd3c8b7e3da99ee53d27a23 (linux v2.6.22) but was missing from musl by accident. in musl the sockios macros are exposed in sys/ioctl.h together with other ioctl requests instead of in sys/socket.h because of namespace rules. (glibc has them in sys/socket.h under _GNU_SOURCE.)
2016-12-15	remove legacy i386 fallback stdarg implementation and framework	Rich Felker	-4/+0
	this has been slated for removal for a long time. there is fundamentally no way to implement stdarg without compiler assistance; any attempt to do so has serious undefined behavior; its working depends not just (as a common misconception goes) on ABI, but also on assumptions about compiler code generation internal to a translation unit, which is not subject to external ABI constraints.
2016-11-11	generalize ELF hash table types not to assume 32-bit entries	Rich Felker	-0/+1
	alpha and s390x gratuitously use 64-bit entries (wasting 2x space and cache utilization) despite the values always being 32-bit. based on patch by Bobby Bingham, with changes suggested by Alexander Monakov to use the public Elf_Symndx type from link.h (and make it properly variable by arch) rather than adding new internal infrastructure for handling the type.
2016-10-20	add bits/hwcap.h and include it in sys/auxv.h	Szabolcs Nagy	-0/+0
	aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
2016-07-03	make brace placement in public header struct definitions consistent	Rich Felker	-12/+6
	placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch//bits -name '.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives.
2016-07-03	fix generic termios.h macro exposure/namespace issues	Szabolcs Nagy	-9/+14
	add EXTA, EXTB, CIBAUD, CMSPAR, XCASE macros and hide them as well as CBAUD, ECHOCTL, ECHOPRT, ECHOKE, FLUSHO, PENDIN in standard mode. the new macros are both in glibc termios.h and in linux asm/termbits.h, the later also contains IBSHIFT and BOTHER, those were not added. these are not standard macros, but some of them are in the reserved namespace so could be exposed, the ones which are not reserved are CIBAUD, CMSPAR and XCASE (which was removed in issue 6), the rest got hidden to be consistent with glibc.
2016-07-03	fix FIOQSIZE in arm ioctl.h	Szabolcs Nagy	-0/+2
	arm ioctl.h is the same as the generic one except this macro, so a workaround solution is used to avoid another ioctl.h copy.
2016-07-03	add missing TIOC* macros to ioctl.h	Szabolcs Nagy	-0/+8
	these are defined in linux asm/ioctls.h. (powerpc64 and powerpc bits/ioctl.h are now identical)
2016-07-03	add missing SIOCSIFNAME from linux/sockios.h to ioctl.h	Szabolcs Nagy	-0/+1
	glibc ioctl.h has it too.
2016-07-03	remove ioctl macros that were removed from linux uapi	Szabolcs Nagy	-4/+0
	TIOCTTYGSTRUCT, TIOCGHAYESESP, TIOCSHAYESESP and TIOCM_MODEM_BITS were removed from the linux uapi and not present in glibc ioctl.h
2016-03-18	deduplicate bits/mman.h	Szabolcs Nagy	-0/+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.
2016-01-27	deduplicate the bulk of the arch bits headers	Rich Felker	-0/+644
	all bits headers that were identical for a number of 'clean' archs are moved to the new arch/generic tree. in addition, a few headers that differed only cosmetically from the new generic version are removed. additional deduplication may be possible in mman.h and in several headers (limits.h, posix.h, stdint.h) that mostly depend on whether the arch is 32- or 64-bit, but they are left alone for now because greater gains are likely possible with more invasive changes to header logic, which is beyond the scope of this commit.
