    configure: Fix -lm test, so that tools can be compiled on hosts that 
require -lm

    The existing test whether "-lm" needs to be included or not is
    insufficient as it reports false negative on Fedora20/ppc64.
    This happens because sin(0.0) is a constant value which compiler
    can safely throw away and therefore there is no need to add "-lm".
    As the result, qemu-nbd/qemu-io/qemu-img tools cannot compile.

    This adds a global variable and uses it in the test to prevent
    from optimization.

    virtio-scsi: scsi events must be converted to target endianness

    Virtio SCSI Events need to be byteswapped before being pushed
    when host and guest have a different endianness. Not doing so
    breaks hotplug of virtio scsi disks, with the following error
    message being printed in the guest console:

    virtio_scsi: Unsupport virtio scsi event 1000000

    This issue got uncovered while testing disk hotplug with a PowerKVM
    ppc64le guest. I have checked that this issue also affects a x86_64
    guest run on a ppc64 host.

    virtio-scsi: virtio_scsi_push_event() lacks VirtIOSCSIReq parsing

    Hotplug of a virtio scsi disk is currently broken: no disk appears in the

        virtio-scsi: start preparing for any_layout

    It modifies virtio_scsi_pop_req() so that it is up to the callers to parse
    the virtio scsi request. It seems that virtio_scsi_push_event() was not
    modified accordingly...

    This patch adds a call to virtio_scsi_parse_req(). It also drops some
    sanity checks that are already performed by virtio_scsi_parse_req().

    vfio: Make BARs native endian

    Slow BAR access path is used when VFIO fails to mmap() BAR.
    Since this is just a transport between the guest and a device, there is
    no need to do endianness swapping.

    This changes BARs to use native endianness. Since non-ROM BARs were
    doing byte swapping, we need to remove it so does the patch.
    As the result, this eliminates cancelling byte swaps and there is
    no change in behavior for non-ROM BARs.

    ROM BARs were declared little endian too but byte swapping was not
    implemented for them so they never actually worked on big endian systems
    as there was no cancelling byte swap. This fixes endiannes for ROM BARs
    by declaring them native endian and only fixing access sizes as it is
    done for non-ROM BARs.

    vfio-pci: Fix MSI-X masking performance

    There are still old guests out there that over-exercise MSI-X masking.
    The current code completely sets-up and tears-down an MSI-X vector on
    the "use" and "release" callbacks.  While this is functional, it can
    slow an old guest to a crawl.  We can easily skip the KVM parts of
    this so that we keep the MSI route and irqfd setup.  We do however
    need to switch VFIO to trigger a different eventfd while masked.
    Actually, we have the option of continuing to use -1 to disable the
    trigger, but by using another EventNotifier we can allow the MSI-X
    core to emulate pending bits and re-fire the vector once unmasked.
    MSI code gets updated as well to use the same setup and teardown
    structures and functions.

    Prior to this change, an igbvf assigned to a RHEL5 guest gets about
    20Mbps and 50 transactions/s with netperf (remote or VF->PF).  With
    this change, we get line rate and 3k transactions/s remote or 2Gbps
    and 6k+ transactions/s to the PF.  No significant change is expected
    for newer guests with more well behaved MSI-X support.
