The tpm_ibmvtpm module is affected by an unaligned access problem. ibmvtpm_crq_get_version failed with rc=-4 during boot when vTPM is enabled in Power partition, which supports both little endian and big endian modes. We added little endian support to fix this problem: 1) added cpu_to_be64 calls to ensure BE data is sent from an LE OS. 2) added be16_to_cpu and be32_to_cpu calls to make sure data received is in LE format on a LE OS.
