Subject[PATCH 5.7 256/265] powerpc/fsl_booke/32: Fix build with CONFIG_RANDOMIZE_BASE
From: Arseny Solokha <>

commit 7e4773f73dcfb92e7e33532162f722ec291e75a4 upstream.

Building the current 5.8 kernel for an e500 machine with
CONFIG_RANDOMIZE_BASE=y and CONFIG_BLOCK=n yields the following

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.
