Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Will Deacon:
 "The diffstat is a bit spread out thanks to an invasive CPU erratum
  workaround which missed the merge window and also a bunch of fixes to
  the recently added MTE selftests.

   - Fixes to MTE kselftests

   - Fix return code from KVM Spectre-v2 hypercall

   - Build fixes for ld.lld and Clang's infamous integrated assembler

   - Ensure RCU is up and running before we use printk()

   - Workaround for Cortex-A77 erratum 1508412

   - Fix linker warnings from unexpected ELF sections

   - Ensure PE/COFF sections are 64k aligned"
