4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Frederic Weisbecker <fweis...@gmail.com> commit 90b62b5129d5cb50f62f40e684de7a1961e57197 upstream. "CHECK" suggests it's only used as a comparison mask. But now it's used further as a config-conditional preempt disabler offset. Lets disambiguate this name.
