wakeup_source_init() has no users. Remove it.
As a result, wakeup_source_prepare() is only called from
wakeup_source_create(). Merge wakeup_source_prepare() into
wakeup_source_create() and remove it.

lures. However, Clang does not implement
calls to "__gnu_mcount_nc" correctly. It does not save the link
register on the stack, which corrupts the stack. The resulting kernel
does not boot.
Disable FUNCTION_TRACER support when building with Clang.

This patch series adds Clang supoprt for gcov.
Patch 1 refactors existing code in preparation for Clang support. Patches
2-3 implement necessary LLVM runtime hooks and gcov kernel interfaces.
Patch 4 simplifies config selection.
