Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
- LPAE fixes for kernel-readonly regions
- Fix for get_user_pages_fast on LPAE systems
- avoid tying decompressor to a particular platform if DEBUG_LL is
enabled
- BUG if we attempt to return to userspace but the to-be-restored PSR
value keeps us in privileged mode (defeating an issue that ftracetest
found)
