[PATCH 02/97] ARM: l2c: remove unnecessary call to outer_flush_all()

[Barry Song]

2014-04-29 3:26 GMT+08:00, Russell King <rmk+kernel at arm.linux.org.uk>:
> outer_disable() is defined to safely turn the L2 cache off without data
> loss: this means that outer_flush_all() should never be called unless
> you need to implement some special L2 cache disabling, and even then
> only from your replacement L2 cache disable function.
