git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux # # Pull arm64 fixes from Will Deacon: # "Catalin's out enjoying the sunshine, so I'm sending the fixes for a # couple of weeks (although there hopefully won't be any more!). # # We've got a revert of a previous fix because it broke the build with # some distro toolchains and a preemption fix when detemining whether or # not the SIMD unit is in use. # # Summary: # # - Revert back to the 'linux' target for LD, as 'elf' breaks some # distributions # # - Fix preemption race when testing whether the vector unit is in use # or not" # #
