Hi all,

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

ERROR: modpost: ".arch_get_random_seed_longs" [arch/powerpc/kvm/kvm-hv.ko] undefined!

Caused by commit

  c3aaaf9e2ada ("powerpc: drop dependency on <asm/machdep.h> in archrandom.h")

It seems that the EXPORT was needed.  I applied the following for today.
