[PATCH] alpha: fix build breakage in asm/cacheflush.h

From: Tejun Heo
Date: Tue Sep 14 2010 - 05:00:56 EST


Alpha SMP flush_icache_user_range() is implemented as an inline
function inside include/asm/cacheflush.h. It dereferences @current
but doesn't include linux/sched.h and thus causes build failure if
linux/sched.h wasn't included previously. Fix it by including the
needed header file explicitly.
