From 6e03bb5ad363fdbe4e1e227cfb78f7978c662e18 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Sat, 3 Apr 2010 12:22:05 +0200 Subject: [PATCH] perf: Always build the powerpc perf_arch_fetch_caller_regs version Now that software events use perf_arch_fetch_caller_regs() too, we need the powerpc version to be always built.
