2008-02-01PCIe: fix double initialization bugMark Lord
Earlier patches to split out the hardware init for PCIe hotplug resulted in some one-time initializations being redone on every resume cycle. Eg. irq/polling initialization. This patch splits the hardware init into two parts, and separates the one-time initializations from those so that they only ever get done once, as intended.

2008-02-01PCI: More Sanity checks for DMARFenghua Yu
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.

2008-02-01PCI: Mem Policy: fix mempolicy usage in pci driverLee Schermerhorn
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.

2007-12-27[PCI] Do not enable CRS Software Visibility by defaultLinus Torvalds
It appears that some PCI-E bridges do the wrong thing in the presense of CRS Software Visibility and MMCONFIG. In particular, it looks like an ATI bridge (device ID 7936) will return 0001 in the vendor ID field of any bridged devices indefinitely. Not enabling CRS SV avoids the problem, and as we currently do not really make good use of the feature anyway (we just time out rather than do any threaded discovery as suggested by the CRS specs), we're better off just not enabling it. This should fix a slew of problem reports with random devices (generally graphics adapters or fairly high-performance networking cards, since it only affected PCI-E) not getting properly recognized on these AMD systems. If we really want to use CRS-SV, we may end up eventually needing a whitelist of systems where this should be enabled, along with some kind of "pcibios_enable_crs()" query to call the system-specific code.
