    Subject[GIT PULL] xen: dom0 support for PCI access
    Date
    Hi Ingo,

    This branch allows a Xen dom0 kernel to access PCI devices properly. Mostly
    this involves making sure that memory being used for DMA is both
    logically contigious in the kernel's pseudo-physical memory and physically
    contigious in machine memory.

    Again, this is pretty much unchanged from the last time I posted it.

    The following changes since commit 0c96e43850feb7c7c4a4950f24533491fbd63b5a:
    Jeremy Fitzhardinge (1):
    xen: checkpatch cleanups
