Subject: alpha: fix build breakage in asm/cacheflush.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b97f897d60c34adb9a5a37a14033e6a867e86f48;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

alpha: fix build breakage in asm/cacheflush.h

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.
