Subject: [PATCH 00/15] hyperv: more stuff to uapi + cleanup

Expose more Hyper-V-related definitions in the uapi header for
consumption by userspace.

While doing so, get rid of a number of duplications between the KVM and
the guest driver code.  Also a few other cleanups are made which are not
strictly necessary for the main purpose of the series but appear
reasonable to do at the same time.

The most controversial is the last patch which modifies the stuff
already published in the uapi header, in the hope that no userspace
applications have started relying on it; I'm ok dropping it if this is
unacceptable.

Roman Kagan (15):
  hyperv: consolidate TSC ref page definitions
  hyperv: uapi-fy synic event flags definitions
  hyperv: use standard bitops
  hyperv: define VMBus message type
  hyperv: GFP_ATOMIC -> GFP_KERNEL
  hyperv: avoid unnecessary vmalloc
  hyperv: dedup cpuid definitions
  hyperv: dedup crash msr related definitions
  hyperv: unify Hyper-V msr definitions
  hyperv: uapi-fy PostMessage and SignalEvent hypercall structures
  hyperv: uapi-fy monitored notification structures
  hyperv: move VMBus connection ids to uapi
  hyperv: move function close to its only callsite
  hyperv_vmbus: drop unused definitions
  hyperv: redefine hv_message without bitfields
