Raghavendra...

Even with this latest patch this branch is broken:

:(.discard+0x6108): multiple definition of `__pcpu_unique_lock_waiting'
arch/x86/xen/built-in.o:(.discard+0x23): first defined here
  CC      drivers/firmware/google/gsmi.o
arch/x86/kernel/built-in.o:(.discard+0x6108): multiple definition of
`__pcpu_unique_lock_waiting'
arch/x86/xen/built-in.o:(.discard+0x23): first defined here
  CC      sound/core/seq/oss/seq_oss_init.o

This is trivially reproducible by doing a build with "make allyesconfig".

Please fix and *verify* it is fixed before resubmitting.

I will be away so Ingo will have to handle the resubmission.
