[PATCH 2/2] perf: Always build the powerpc perf_arch_fetch_caller_regs version
in [Kernel]
|
From: Frederic Weisbecker on 3 Apr 2010 06:50 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(a)ellerman.id.au> Reported-by: Ingo Molnar <mingo(a)elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec(a)gmail.com> Cc: Peter Zijlstra <a.p.zijlstra(a)chello.nl> Cc: Arnaldo Carvalho de Melo <acme(a)redhat.com> Cc: Paul Mackerras <paulus(a)samba.org> --- arch/powerpc/kernel/misc.S | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-) diff --git a/arch/powerpc/kernel/misc.S b/arch/powerpc/kernel/misc.S index b485a87..22e507c 100644 --- a/arch/powerpc/kernel/misc.S +++ b/arch/powerpc/kernel/misc.S @@ -128,7 +128,6 @@ _GLOBAL(__restore_cpu_power7) /* place holder */ blr -#ifdef CONFIG_EVENT_TRACING /* * Get a minimal set of registers for our caller's nth caller. * r3 = regs pointer, r5 = n. @@ -154,4 +153,3 @@ _GLOBAL(perf_arch_fetch_caller_regs) PPC_STL r4,_NIP-STACK_FRAME_OVERHEAD(r3) PPC_STL r7,_LINK-STACK_FRAME_OVERHEAD(r3) blr -#endif /* CONFIG_EVENT_TRACING */ -- 1.6.2.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
