Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fix from Will Deacon: "It's been pretty quiet on the fixes side of things for us, but Artem reported a build failure introduced during the merge window that appears with older GCCs that do not support asm goto. The fix is bigger than I'd like, but it's a mechnical move of some constants to break an include dependency between atomic.h and jump_label.h when !HAVE_JUMP_LABEL. Summary: - Fix build failure on compilers without asm goto" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Fix circular include of asm/lse.h through linux/jump_label.h
