commit 2d66557e88297ac72d9256cf0725522d13949fd9
Author: Dmitry V. Levin <ldv@altlinux.org>

    linux/aarch64: sync sys/ptrace.h with Linux 4.15 [BZ #22433]
    
    Remove compat-specific constants that were never exported by kernel
    headers under these names.  Before linux commit v3.7-rc1~16^2~1 they
    were exported with COMPAT_ prefix, and since that commit they are not
    exported at all.
    
    * sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (__ptrace_request):
    Remove arm-specific PTRACE_GET_THREAD_AREA, PTRACE_GETHBPREGS,
    and PTRACE_SETHBPREGS.
    
    (cherry picked from commit 2fd4bbaa1446f1be700e10c526cf585a796c4991)
