    Subject[GIT PULL] xen: core dom0 support
    Date
    Hi Ingo,

    This branch has the basics of Xen dom0 support. It is not sufficient
    to get a booting system (it implements no access to physical devices),
    but it is enough to at least get the kernel to start and print some
    console messages.

    This is essentially unchanged from the last time I posted it.

    The following changes since commit e7c064889606aab3569669078c69b87b2c527e72:
    Jeremy Fitzhardinge (1):
    xen: add FIX_TEXT_POKE to fixmap

    are available in the git repository at:

    git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git xen-tip/dom0/core

    Christophe Saout (1):
    paravirtualize IO permission bitmap

    Ian Campbell (4):
    xen: disable PAT

    xen/dom0: add XEN_DOM0 config option
    x86: make /dev/mem mappings _PAGE_IOMAP
    x86: don't need "changed" parameter for set_io_bitmap()
