Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "Three fixes this time around:

   - Two fixes for noMMU, fixing the decompressor header layout, and
     preventing a build error with some configurations.

   - Fixing the hyp-stub updates that went in during the merge window
     for platforms that use MCPM"

* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
  ARM: 8677/1: boot/compressed: fix decompressor header layout for v7-M
  ARM: 8676/1: NOMMU: provide pgprot_device() macro
  ARM: 8675/1: MCPM: ensure not to enter __hyp_soft_restart from loopback and cpu_power_down
