I'm seeing a build regression on arm64 for tools/perf.

On linux-4.1, it builds fine.

On linux-4.2-rc1, it dies with this relevant message (skipping the
missing defines, etc):

/home/mlangsdorf/tmp/linux-4.2/include/linux/preempt.h: At top level:
/home/mlangsdorf/tmp/linux-4.2/include/linux/preempt.h:64:25: fatal 
error: asm/preempt.h: No such file or directory
  #include <asm/preempt.h>

On both versions, arch/arm64/include/generated/asm/preempt.h
exists. I'm guessing something changed in the build system so
that's its not being picked up for 4.2-rc1 but I'm not sure where
to look.
