Subject: [PATCH] smp_call_function_single() cleanup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a3bc0dbc81d36fd38991b4373f6de8e1a507605a;p=linux-beck.git

[PATCH] smp_call_function_single() cleanup

If we're going to implement smp_call_function_single() on three architecture
with the same prototype then it should have a declaration in a
non-arch-specific header file.

Move it into <linux/smp.h>.
