From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Hi, The kbuild robot reported build breakage of nds32 architecture [1] that happens with CONFIG_CPU_CACHE_ALIASING=n and CONFIG_HUGHMEM=y. There are two issues: one with a missing macro during conversion of page folding and another one is a conflict between cacheflush.h definitions in arch/nds32 and asm-generic.
