Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
- update unwinder to cope with module PLTs
- enable UBSAN on ARM
- improve kernel fault message
- update UEFI runtime page tables dump
- avoid clang's __aeabi_uldivmod generated in NWFPE code
- disable FIQs on CPU shutdown paths
- update XOR register usage
- a number of build updates (using .arch, thread pointer, removal of
lazy evaluation in Makefile)
- conversion of stacktrace code to stackwalk
- findbit assembly updates
- hwcap feature updates for ARMv8 CPUs
- instruction dump updates for big-endian platforms
- support for function error injection
