Subject: linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: ".perf_arch_fetch_caller_regs" [fs/xfs/xfs.ko] undefined!
ERROR: ".perf_arch_fetch_caller_regs" [arch/powerpc/platforms/cell/spufs/spufs.ko] undefined!

Caused by commit 5331d7b84613b8325362dde53dc2bff2fb87d351 ("perf:
Introduce new perf_fetch_caller_regs() for hot regs snapshot") from the
tip tree.  Presumably commit 639fe4b12f92b54c9c3b38c82cdafaa38cfd3e63
("perf: export perf_trace_regs and perf_arch_fetch_caller_regs") should
have exported the weak version as well as the x86 one.

I have used the version of the tip tree from next-20100311 for today.
