2018-07-17	add support for arch-specific ptrace command macros	Szabolcs Nagy	1	-0/+2
	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).
2018-06-26	add m68k reg.h and user.h	Rich Felker	2	-0/+78

2018-06-20	fix m68k float.h long double exponent range	Rich Felker	1	-2/+2
	unlike the x86 variant, the m68k ld80 format allows (biased) exponent zero with mantissa msb set, thereby extending the normal range.
2018-06-20	work around broken kernel struct ipc_perm on some big endian archs	Rich Felker	1	-0/+1
	the mode member of struct ipc_perm is specified by POSIX to have type mode_t, which is uniformly defined as unsigned int. however, Linux defines it with type __kernel_mode_t, and defines __kernel_mode_t as unsigned short on some archs. since there is a subsequent padding field, treating it as a 32-bit unsigned int works on little endian archs, but the order is backwards on big endian archs with the erroneous definition. since multiple archs are affected, remedy the situation with fixup code in the affected functions (shmctl, semctl, and msgctl) rather than repeating the same shims in syscall_arch.h for every affected arch.
2018-06-19	add m68k port	Rich Felker	17	-0/+847
	three ABIs are supported: the default with 68881 80-bit fpu format and results returned in floating point registers, softfloat-only with the same format, and coldfire fpu with IEEE single/double only. only the first is tested at all, and only under qemu which has fpu emulation bugs. basic functionality smoke tests have been performed for the most common arch-specific breakage via libc-test and qemu user-level emulation. some sysvipc failures remain, but are shared with other big endian archs and will be fixed separately.
