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

are available in the git repository at:

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

Alex Nixon (7):
xen: Don't disable the I/O space
xen: Allow unprivileged Xen domains to create iomap pages
Xen: Rename the balloon lock
xen: Add xen_create_contiguous_region
x86/PCI: Clean up pci_cache_line_size
x86/PCI: Enable scanning of all pci functions
Xen/x86/PCI: Add support for the Xen PCI subsytem

Jeremy Fitzhardinge (4):
xen/swiotlb: use dma_alloc_from_coherent to get device coherent memory
x86/pci: make sure _PAGE_IOMAP it set on pci mappings
xen/pci: clean up Kconfig a bit
xen: checkpatch cleanups
