Subject: [PATCH] ARM: imx: compile fix for hotplug.c
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Commit bca7a5a (ARM: cpu hotplug: remove majority of cache flushing
from platforms) removes include of <asm/cacheflush.h> and hence
discovers a few indirect inclusion and declaration problems as below.

Fix them by adding the needed inclusion and declaration.
