Date: Tue, 11 Jun 2019 12:24:32 +0200	[thread overview]
Message-ID: <mvm7e9spggv.fsf@suse.de> (raw)

Before 58de77545e53 ("riscv: move flush_icache_{all,mm} to cacheflush.c"),
flush_icache_all was a macro, but it is used by a module:

  ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined!
