[PATCH 0/3] convert dynamic_debug to use jump labels

Hi,

In the course of adding jump label support to dynamic_debug (patch #3), I
found the inclusion of <linux/bug.h> by <linux/jump_label.h> to problematic b/c
it includes <linux/kernel.h> (thus, creating circular include dependencies).
Thus, patch #1 splits jump_label.h such that 'struct static_key' and
static_branch_[un]likely() can be used with minimail dependencies. I think this
is consistent with how this facility is often used, and should be useful for
other use-cases as well.

Patch #2 was required to get powerpc to compile.

Thanks,

-Jason
