Subject: [PATCH] xtensa: fix flush_icache_user_range in noMMU configs
Date: Mon, 25 May 2020 15:15:56 -0700	[thread overview]
Message-ID: <> (raw)

flush_icache_user_range definition for xtensa is placed under
preprocessor condition that is not processed in noMMU configurations,
resulting in the following build errors:

  fs/exec.c:1065:3: error: implicit declaration of function
  fs/binfmt_flat.c:857:2: error: implicit declaration of function

Move definition outside conditional compilation block.

Fixes: 134d96d05d30 ("xtensa: implement flush_icache_user_range")
