Dmitry Levin - Dec. 30, 2017, 12:08 a.m.
Clone generic linux/sys/ptrace.h, remove x86-specific PTRACE_GETFPXREGS
and PTRACE_SETFPXREGS constants, add the following arm-specific
__ptrace_request constants: PTRACE_GETWMMXREGS, PTRACE_SETWMMXREGS,
PTRACE_GET_THREAD_AREA, PTRACE_SET_SYSCALL, PTRACE_GETCRUNCHREGS,
PTRACE_SETCRUNCHREGS, PTRACE_GETVFPREGS, PTRACE_SETVFPREGS,
PTRACE_GETHBPREGS, PTRACE_SETHBPREGS, and PTRACE_GETFDPIC.

Tested with strace.

[BZ #22433]
* sysdeps/unix/sysv/linux/arm/sys/ptrace.h: New file.

OK, with the copyright year range changed to end with 2018.
