Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Allow booting of late secondary CPUs affected by erratum 1418040
(currently they are parked if none of the early CPUs are affected by
this erratum).
- Add the 32-bit vdso Makefile to the vdso_install rule so that 'make
vdso_install' installs the 32-bit compat vdso when it is compiled.
- Print a warning that untrusted guests without a CPU erratum
workaround (Cortex-A57 832075) may deadlock the affected system.
