Subject: [PATCH 2/2] perf: Always build the powerpc perf_arch_fetch_caller_regs version
Date: Sat,  3 Apr 2010 12:47:39 +0200	[thread overview]
Message-ID: <1270291659-6299-3-git-send-regression-fweisbec@gmail.com> (raw)
In-Reply-To: <1270291659-6299-1-git-send-regression-fweisbec@gmail.com>

Now that software events use perf_arch_fetch_caller_regs() too, we
need the powerpc version to be always built.

Fixes the following build error:

	(.text+0x3210): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x3324): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x33bc): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0x33ec): undefined reference to `perf_arch_fetch_caller_regs'
	(.text+0xd4a0): undefined reference to `perf_arch_fetch_caller_regs'
	arch/powerpc/kernel/built-in.o:(.text+0xd528): more undefined references to `perf_arch_fetch_caller_regs' follow
	make[1]: *** [.tmp_vmlinux1] Error 1
	make: *** [sub-make] Error 2
