Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"Here are a few more arm64 fixes for 4.3. Again, nothing too
significant, but worth having nonetheless. The MINSIGSTKSZ update is
a bit grotty, but the value we currently have is wrong (too small), so
anybody using that will have issues already. It has Arnd's ack for
the asm-generic change.
Summary:
- Fix module CFLAGS setting in workaround for erratum #843419
- Update MINSIGSTKSZ and SIGSTKSZ to match glibc
- Wire up some new compat syscalls"
