Building the current 5.8 kernel for an e500 machine with CONFIG_RANDOMIZE_BASE=y and CONFIG_BLOCK=n 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'? Indeed, including asm/cacheflush.h into kaslr_booke.c fixes the build.
