Subject: linux-next: build failure after merge of the clk tree

Hi Mike,

After merging the clk tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from arch/x86/include/asm/bug.h:35:0,

Caused by commit 9a2027b99994 ("clk: Really fix deadlock with
mmap_sem").  I wonder how this ever built?

I have used the clk tree from next-20141215 for today.
