The code goes so far as to set the default return code to -ENOSYS but
then overrides this to -EINVAL in the switch() statement's default
case.
This patch removes this pointless and incorrect override.

This patch series follows on from my recent Xen series [1], to provide
support in privcmd for de-privileging of device emulators.

Paul Durrant (3):
xen/privcmd: return -ENOSYS for unimplemented IOCTLs
xen/privcmd: Add
gateway for __HYPERVISOR_dm_op,
bouncing the callers buffers through kernel memory to allow the address
ranges to be audited (and negating the need to bounce through locked
memory in user-space).

The Xen docs specify several flags which a guest can set to advertize
which values of the xenstore control/shutdown key it will recognize.
This patch adds code to write all the relevant feature-flag keys.
