Add and changes a few sanity checks in dmar.c. 1. The haw field in ACPI DMAR table in VT-d spec doesn't describe the range of haw. But since DMA page size is 4KB in DMA remapping, haw should be at least 4KB. The current VT-d code in dmar.c returns failure when haw==0. This sanity check is not accurate and execution can pass when haw is less than one page size 4KB. This patch changes the haw sanity check to validate if haw is less than 4KB. 2. Add dmar_rmrr_units verification. 3. Add parse_dmar_table() verification. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

sys_pciconfig_{read,write}() are protected against PCI removal with the reference count in struct pci_dev. The concurrency of pci_user_{read,write}_config_* functions are already protected by pci_lock in drivers/pci/access.c. Signed-off-by:Diego Woitasen <diego@woitasen.com.ar> Signed-off-by:

The vendor_compatible and device_compatible fields in struct pci_dev aren't used anywhere, and are somewhat pointless. Assuming that these are historical artifacts, remove them. Signed-off-by:

In an attempt to ensure memory allocation from the local node, the pci driver temporarily replaces the current task's memory policy with the system default policy. Trying to be a good citizen, the driver then call's mpol_get() on the new policy. When it's finished probing, it undoes the '_get by calling mpol_free() [on the system default policy] and then restores the current task's saved mempolicy. A couple of issues here: 1) it's never necessary to set a task's mempolicy to the system default policy in order to get system default allocation behavior. Simply set the current task's mempolicy to NULL and allocations will fall back to system default policy. 2) we should never [need to] call mpol_free() on the system default policy. [I plan on trapping this with a VM_BUG_ON() in a subsequent patch.] This patch removes the calls to mpol_get() and mpol_free() and uses NULL for the temporary task mempolicy to effect default allocation behavior.

PCI Bus Parking and PCI Master read caching on the VIA CX700 is buggy and can lead to problems such as USB2.0 packet loss if a VT6212L controller is on the PCI bus. It's disabled by default, but some BIOSes turn these features on and this patch reverts the configuration to the safe defaults. Signed-off-by:

It blindly copies everything in the io_context, including the lock. That doesn't work so well for either lock ordering or lockdep. There seems zero point in swapping io contexts on a request to request merge, so the best point of action is to just remove it. Signed-off-by:Jens Axboe <jens.axboe@oracle.com>

Modify Makefiles to support separate coldfire platform directory. Currently the common ColdFire CPU family code sits in the arch/m68knommu/platform/5307 directory. This is confusing, the files containing this common code are in no way specific to the 5307 ColdFire. Create an arch/m68knommu/platform/coldfire directory to contain this common code. Other m68knommu CPU varients do not need use this code though, so it doesn't make sense to move it to arch/m68knommu/kernel. Signed-off-by:
