I'm 99% sure there's no connection between the two implementations,
other than the name.

So splitting the patch by arch would make it easier to merge. I'm
reluctant to merge changes to sparc code.

The list of powerpc specific drivers is:

  drivers/char/hw_random/pseries-rng.c
  drivers/char/tpm/tpm_ibmvtpm.c
  drivers/crypto/nx/nx-842-pseries.c
  drivers/crypto/nx/nx.c
  drivers/misc/ibmvmc.c
  drivers/net/ethernet/ibm/ibmveth.c
  drivers/net/ethernet/ibm/ibmvnic.c
  drivers/scsi/ibmvscsi/ibmvfc.c
  drivers/scsi/ibmvscsi/ibmvscsi.c
  drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c
  drivers/tty/hvc/hvcs.c

cheers
