[PATCH v6 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.
