Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:

 - amba bus irq rework

 - add kfence support

 - support for Cortex M33 and M55 CPUs

 - kbuild updates for decompressor

 - let core code manage thread_info::cpu

 - avoid unpredictable NOP encoding in decompressor

 - reduce information printed in calltraces
