Merge branch 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security

Pull TPM updates from James Morris:

 - Support for partial reads of /dev/tpm0.

 - Clean up for TPM 1.x code: move the commands to tpm1-cmd.c and make
   everything to use the same data structure for building TPM commands
   i.e. struct tpm_buf.

* 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (25 commits)
