Apart from the kprobes build failure (patch available already), I found
two more:

- with CONFIG_KASAN enabled:

arch/arm64/lib/memmove.o: in function `__pi_memmove':
arch/arm64/lib/memmove.S:57:(.text+0xc): relocation truncated to fit: R_AARCH64_CONDBR19 against symbol `memcpy' defined in .text section in mm/kasan/common.o

- big endian (I think kbuild robot also reported this):

arch/arm64/lib/strcmp.S: Assembler messages:
arch/arm64/lib/strcmp.S:118: Error: immediate value out of range 0 to 63 at operand 3 -- `lsr x2,x2,#560'

I'll drop the series for now (already removed it from for-next/core
yesterday) until the above are addressed.

Thanks Catalin - I've already fixed the big-endian typo locally, and for 
the KASAN thing it seems we probably just overlooked an 
s/memcpy/__memcpy/ conversion, but I'll double-check before resending.

Robin.
