[PATCH v2] btrfs: set task state with schedule_timeout_uninterruptible()
schedule_timeout() is used without setting state to STATE_(UN)INTERRUPTIBLE. As it is called without checking of pending signals, use schedule_timeout_uninterruptible() instead.

[PATCH 3/9] xen: Rename the balloon lock
From: Alex Nixon <alex.nixon(a)citrix.com> * xen_create_contiguous_region needs access to the balloon lock to ensure memory doesn't change under its feet, so expose the balloon lock * Change the name of the lock to xen_reservation_lock, to imply it's now less-specific usage. [ Impact: cleanup ] Signed-... 27 Jul 2010 13:57

[PATCH 6/9] xen/mmu: inhibit vmap aliases rather than trying to clear them out
From: Jeremy Fitzhardinge <jeremy.fitzhardinge(a)citrix.com> Rather than trying to deal with aliases once they appear, just completely inhibit them. Mostly the removal of aliases was managable, but it comes unstuck in xen_create_contiguous_region() because it gets executed at interrupt time (as a result of dma_all... 27 Jul 2010 13:57

[PATCH 9/9] x86: Detect whether we should use Xen SWIOTLB.
It is paramount that we call pci_xen_swiotlb_detect before pci_swiotlb_detect as both implementations use the 'swiotlb' and 'swiotlb_force' flags. The pci-xen_swiotlb_detect inhibits the swiotlb_force and swiotlb flag so that the native SWIOTLB implementation is not enabled when running under Xen. Signed-off-by:... 27 Jul 2010 13:57

[PATCH 4/9] xen: Add xen_create_contiguous_region
From: Alex Nixon <alex.nixon(a)citrix.com> A memory region must be physically contiguous in order to be accessed through DMA. This patch adds xen_create_contiguous_region, which ensures a region of contiguous virtual memory is also physically contiguous. Based on Stephen Tweedie's port of the 2.6.18-xen version... 27 Jul 2010 13:57

[PATCH] Xen-SWIOTLB v0.8.6 used for Xen PCI pass through for PV guests.
Changes since last posting [v0.8.3 (http://lkml.org/lkml/2010/6/22/310)]: - Coalesced the Xen-SWIOTLB set of patches in one patch. - Moved the swiotlb-xen.c to drivers/xen. - Added Ack's, Cc's, as appropriate. This patchset: These nine patches lay the groundwork for Xen Paravirtualized (PV) domains to acce... 27 Jul 2010 13:57

[PATCH 5/9] vmap: add flag to allow lazy unmap to be disabled at runtime

[PATCH 8/9] pci-swiotlb-xen: Add glue code to setup dma_ops utilizing xen_swiotlb_* functions.
We add the glue code that sets up a dma_ops structure with the xen_swiotlb_* functions. The code turns on xen_swiotlb flag when it detects it is running under Xen and it is either in privileged mode or the iommu=soft flag was passed in. It also disables the bare-metal SWIOTLB if the Xen-SWIOTLB has been enabled.... 27 Jul 2010 13:57

[PATCH 2/9] xen: Allow unprivileged Xen domains to create iomap pages
From: Alex Nixon <alex.nixon(a)citrix.com> PV DomU domains are allowed to map hardware MFNs for PCI passthrough, but are not generally allowed to map raw machine pages. In particular, various pieces of code try to map DMI and ACPI tables in the ISA ROM range. We disallow _PAGE_IOMAP for those mappings, so that th... 27 Jul 2010 13:57
