[PATCH v2 0/5] Drivers: hv: cleanup VMBus messages handling

[Vitaly Kuznetsov]

A small cleanup series mostly aimed at sanitizing memory we pass to
message handlers: not passing garbage/lefrtovers from other messages
and making sure we fail early when hypervisor misbehaves.

No (real) functional change intended.

Changes since v1:
- Check that the payload size specified by the host is <= 240 bytes
- Add Michael's R-b tags.

Vitaly Kuznetsov (5):
  Drivers: hv: copy from message page only what's needed
  Drivers: hv: allocate the exact needed memory for messages
  Drivers: hv: avoid passing opaque pointer to vmbus_onmessage()
  Drivers: hv: make sure that 'struct vmbus_channel_message_header'
    compiles correctly
  Drivers: hv: check VMBus messages lengths
