From c2b78c8e82f2b8aa0e8703f9931d42ad4f041260 Mon Sep 17 00:00:00 2001 From: David VomLehn Date: Tue, 13 Jul 2010 00:41:12 +0900 Subject: MIPS: PowerTV: Provide cpu-feature-overrides.h This will optimize fls() and __fls() to use CLZ throughout the kernel, and any other optimizations that depend on constant cpu_has_* values will also be used.
