Subject: [PATCH 0/2] fix recent nds32 build breakage

From: Mike Rapoport <rppt@...ux.ibm.com>

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.

Mike Rapoport (2):
  asm-generic/nds32: don't redefine cacheflush primitives
  nds32: fix build failure caused by page table folding updates
