When building kfence the following error shows up:
In file included from mm/kfence/report.c:13:
arch/arm64/include/asm/kfence.h: In function ‘kfence_protect_page’:
arch/arm64/include/asm/kfence.h:12:2: error: implicit declaration of function
‘set_memory_valid’ [-Werror=implicit-function-declaration]
12 | set_memory_valid(addr, 1, !protect);
| ^~~~~~~~~~~~~~~~
Use the correct include both
f2b7c491916d ("set_memory: allow querying whether set_direct_map_*() is
actually enabled")
and 4c4c75881536 ("arm64, kfence: enable KFENCE for ARM64") went in the
same day via different trees.

I got this build error in todays next-20201204.
Andrew, since both patches are in your -mm tree, I think this can be
folded into 4c4c75881536 ("arm64, kfence: enable KFENCE for ARM64")
