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. 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 Reported-by: Michael Ellerman <michael@ellerman.id.au> Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Paul Mackerras <paulus@samba.org>
