Subject: [PATCH v2 0/3]  Extend the vTPM proxy driver to pass locality to emulator

The purpose of this series of patches is to enable the passing of the locality
a command is executing in to a TPM emulator. To enable this we introduce a new
flag for the device creation ioctl that requests that the locality be prepended
to every command. For applications to check which flags the driver supports, we
add a new ioctl that returns a bitmask of supported flags.

v1->v2:
  - fixed return value from function in patch 3/3

Stefan Berger (3):
  tpm: vtpm_proxy: Add ioctl to get supported flags
  tpm: vtpm_proxy: Implement request_locality
  tpm: vtpm_proxy: Add ioctl to request locality prepended to command
