[PATCH 0/2] Move the tpm_get_random api and add an hwrng driver for it

[Kent Yoder <key@linux.vnet.ibm.com>]

These patches move the tpm_get_random API out of the trusted keys code
and into the tpm device driver itself.  Then a hwrng driver is added that
makes use of the API to provide a H/W RNG source.

  These are based off the latest upstream kernel.

Thanks,
Kent
