commit 89983cb37c9319806a551e8fe9f3a11ff8f973e1
Author: Joseph Myers <joseph@codesourcery.com>

Update siginfo constants from Linux kernel (bug 21286).
As of Linux 4.17, siginfo headers in the Linux kernel have been
largely unified across architectures (so various constants are defined
with common values in include/uapi/asm-generic/siginfo.h even if not
all architectures can generate those particular constants).
This patch makes glibc reflect that unification and the current set of
constants in that header as of Linux 4.18. Various constants are
added to bits/siginfo-consts.h (under the same feature test macro
conditions as the other constants with the same prefix), and removed
from the ia64 bits/siginfo-consts-arch.h where they were previously
there - this is not limited to constants added by the unification.
Nothing is done about macros that are defined in
include/uapi/asm-generic/siginfo.h with names with leading '__' (some
of those are ia64-specific ones that remain in the ia64
bits/siginfo-consts-arch.h without the leading '__' there).
A consequence of these changes is that TRAP_HWBKPT becomes available
on AArch64 and all other architectures as requested in bug 21286.
Tested for x86_64; tested with build-many-glibcs.py for ia64.
