git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip Pull Xen updates from Konrad Rzeszutek Wilk: "This has tons of fixes and two major features which are concentrated around the Xen SWIOTLB library. The short <blurb> is that the tracing facility (just one function) has been added to SWIOTLB to make it easier to track I/O progress. Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver "is used to translate physical to machine and machine to physical addresses of foreign[guest] pages for DMA operations" (Stefano) when booting under hardware without proper IOMMU. There are also bug-fixes, cleanups, compile warning fixes, etc. The commit times for some of the commits is a bit fresh - that is b/c we wanted to make sure we have the Ack's from the ARM folks - which with the string of back-to-back conferences took a bit of time. Rest assured - the code has been stewing in #linux-next for some time. Features: - SWIOTLB has tracing added when doing bounce buffer. - Xen ARM/ARM64 can use Xen-SWIOTLB. This work allows Linux to safely program real devices for DMA operations when running as a guest on Xen on ARM, without IOMMU support. [*1] - xen_raw_printk works with PVHVM guests if needed. Bug-fixes: - Make memory ballooning work under HVM with large MMIO region. - Inform hypervisor of MCFG regions found in ACPI DSDT. - Remove deprecated IRQF_DISABLED. - Remove deprecated __cpuinit. [*1]: "On arm and arm64 all Xen guests, including dom0, run with second stage translation enabled. As a consequence when dom0 programs a device for a DMA operation is going to use (pseudo) physical addresses instead machine addresses. This work introduces two trees to track physical to machine and machine to physical mappings of foreign pages. Local pages are assumed mapped 1:1 (physical address == machine address). It enables the SWIOTLB-Xen driver on ARM and ARM64, so that Linux can translate physical addresses to machine addresses for dma operations when necessary.
