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) * 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: BUG if jumping to usermode address in kernel mode ARM: 8722/1: mm: make STRICT_KERNEL_RWX effective for LPAE ARM: 8721/1: mm: dump: check hardware RO bit for LPAE ARM: make decompressor debug output user selectable ARM: fix get_user_pages_fast
