Building the current 5.8 kernel for a e500 machine with
CONFIG_RANDOMIZE_BASE set yields the following failure:
arch/powerpc/mm/nohash/kaslr_booke.c: In function 'kaslr_early_init':
arch/powerpc/mm/nohash/kaslr_booke.c:387:2: error: implicit declaration
of function 'flush_icache_range'; did you mean 'flush_tlb_range'?
[-Werror=implicit-function-declaration]
Indeed, including asm/cacheflush.h into kaslr_booke.c fixes the build.
The issue dates back to the introduction of that file and probably went
unnoticed because there's no in-tree defconfig with CONFIG_RANDOMIZE_BASE
set.
