[SRU][Xenial][PATCH 0/6]UBUNTU: SAUCE:(noup) Fixes for LP:1570124

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1570124

== SRU Justification ==

The six patches in this patch set are requested for Hyper-V.

Some additional patches for PCI Passthrough have been submitted but not accepted 
upstream that are necessary for accessing multiple GPUs on the host. 
These patches are expected to get accepted upstream.  However, the are needed in
Xenial, so they are being reqeusted as SAUCE patches until they land upstream.



== Fixes ==
drivers:hv: Separate out frame buffer logic when picking MMIO range
drivers:hv: Record MMIO range in use by frame buffer
drivers:hv: Track allocations of children of hv_vmbus in private resource tree
drivers:hv: Reverse order of resources in hyperv_mmio
drivers:hv: Call vmbus_mmio_free() to reverse vmbus_mmio_allocate()
drivers:hv: Lock access to hyperv_mmio resource tree



== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
