[PATCH 1/4] Various VT-d code cleanup
This patch maps RMRR in intel_iommu_add_device() if the device has RMRR;
move domain_context_mapping() to be in front of list_move() in
reassign_device_ownership().
Currently, hypervisor sets up devices and RMRR for dom0, and dom0 also
adds devices for itself via hypercall. This is obviously duplicate. In
order to allow old dom0 kernels to work with iommu-capable platforms,
maybe it cannot be...

Megaraid SAS driver failing in Xen-3.3.0 but was working in Xen-3.2.2-rc3
On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled.
It fails at the point of initializing firmware.
I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working.
Looks like a degrade problem.
Any clues?
Thx,
Venkat

[PATCH 0/4] Various VT-d code cleanup
The patches are as follows:
Patch 1: Map RMRR in intel_iommu_add_device() if the device has RMRR;
move domain_context_mapping() to be in front of list_move() in
reassign_device_ownership().
Patch 2: There is only one INCLUDE_ALL DMAR unit in system, but no
restriction on whether it''s the last unit.
Patch 3: Change code style of pci.c file, and add
spin_unlock(&pdev->lock) when iommu_add_device() fails....
