[PATCH v5 00/11] Multi-instance vTPM driver

[Stefan Berger <stefanb-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

The following series of patches implements a multi-instance vTPM driver
that can dynamically create TPM 'server' and client device pairs.

Using an ioctl on the provided /dev/vtpmx, a client-side vTPM device
and a server side file descriptor is created. The file descriptor must
be passed to a TPM emulator. The device driver will initialize the
emulated TPM using TPM 1.2 or TPM 2 startup commands and it will read
the command durations from the device in case of a TPM 1.2. The choice
of emulated TPM device (1.2 or 2) must be provided with a flag in
the ioctl.

The driver is based on James Morris's 'next' branch and uses several
recently posted patches from Jason and Jarkko. Some of these patches
needed to rebased on top of this tree.
