Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-xl-multivcpu  3 host-install(3)        broken REGR. vs. 38680
 test-amd64-amd64-xl-qemuu-debianhvm-amd64 3 host-install(3) broken REGR. vs. 
38680
 test-amd64-amd64-amd64-pvgrub 10 guest-start              fail REGR. vs. 38680

commit 95239e162518dc6577164be3d9a789aba7f591a3
Author: Alex Williamson <alex.williamson@xxxxxxxxxx>
Date:   Tue Jan 19 11:33:42 2016 -0700

    vfio/pci: Lazy PBA emulation
    
    The PCI spec recommends devices use additional alignment for MSI-X
    data structures to allow software to map them to separate processor
    pages.  One advantage of doing this is that we can emulate those data
    structures without a significant performance impact to the operation
    of the device.  Some devices fail to implement that suggestion and
    assigned device performance suffers.
    
    One such case of this is a Mellanox MT27500 series, ConnectX-3 VF,
    where the MSI-X vector table and PBA are aligned on separate 4K
    pages.  If PBA emulation is enabled, performance suffers.  It's not
    clear how much value we get from PBA emulation, but the solution here
    is to only lazily enable the emulated PBA when a masked MSI-X vector
    fires.  We then attempt to more aggresively disable the PBA memory
    region any time a vector is unmasked.  The expectation is then that
    a typical VM will run entirely with PBA emulation disabled, and only
    when used is that emulation re-enabled.

commit f5793fd9e1fd89808f4adbfe690235b094176a37
Author: Alex Williamson <alex.williamson@xxxxxxxxxx>
Date:   Tue Jan 19 11:33:41 2016 -0700

    vfio/pci-quirks: Only quirk to size of PCI config space
    
    For quirks that support the full PCIe extended config space, limit the
    quirk to only the size of config space available through vfio.  This
    allows host systems with broken MMCONFIG regions to still make use of
    these quirks without generating bad address faults trying to access
    beyond the end of config space exposed through vfio.  This may expose
    direct access to the mirror of extended config space, only trapping
    the sub-range of standard config space, but allowing this makes the
    quirk, and thus the device, functional.  We expect that only device
    specific accesses make use of the mirror, not general extended PCI
    capability accesses, so any virtualization in this space is likely
    unnecessary anyway, and the device is still IOMMU isolated, so it
    should only be able to hurt itself through any bogus configurations
    enabled by this space.
