[PATCH 21/24] ARM64:ILP32: The native siginfo is used instead of the compat siginfo.

From: Andrew Pinski <hidden>
Date: 2014-05-24 07:02:57
Also in: lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

Set COMPAT_USE_NATIVE_SIGINFO to be true for non AARCH32 tasks.  The same reasoning why we check AARCH32 as we did for COMPAT_USE_64BIT_TIME_T.

Thanks,
Andrew Pinski
