      intel-agp: add chipset flushing support · 6c00a61e
      由 Dave Airlie 提交于 
      This adds support for flushing the chipsets on the 915, 945, 965 and G33
families of Intel chips.

The BIOS doesn't seem to always allocate the BAR on the 965 chipsets
so I have to use pci resource code to create a resource

It adds an export for pcibios_align_resource.

      x86: serverworks: IRQ routing needs no _p · c11b68bc
      由 Alan Cox 提交于 
      I can find no reason for the _p on the serverworks IRQ routing logic, and
a review of the documentation contains no indication that any such delay
is needed so lets try this

      x86: add some pirq debugging · 7d409d60
      由 Ingo Molnar 提交于 
      we use a few static mapping rules in our pirq routing functions,
and for example regression f3ac8432 was due to the pirq
being out of range of the remapping array. Put in a few
WARN_ON_ONCE() lines so that we get notified about any such
out-of-bound incidents.

      PCI: remove default PCI expansion ROM memory allocation · 9f8dacca
      由 Gary Hade 提交于 
      increasing number of PCI slots in large multi-node systems.  The kernel
currently attempts by default to allocate memory for all PCI expansion
ROMs so there has also been an increasing number of PCI memory
allocation failures seen on these systems.  This occurs because the BIOS
either (1) provides insufficient PCI memory resource for all the
expansion ROMs or (2) provides adequate PCI memory resource for
expansion ROMs but provides the space in kernel unexpected BIOS assigned
P2P non-prefetch windows.

The resulting PCI memory allocation failures may be benign when related
to memory requests for expansion ROMs themselves but in some cases they
can occur when attempting to allocate space for more critical BARs.
This can happen when a successful expansion ROM allocation request
consumes memory resource that was intended for a non-ROM BAR.  We have
seen this happen during PCI hotplug of an adapter that contains a P2P
bridge where successful memory allocation for an expansion ROM BAR on
device behind the bridge consumed memory that was intended for a non-ROM
BAR on the P2P bridge.  In all cases the allocation failure messages can
be very confusing for users.

This patch addresses the issue by changing the kernel default behavior
so that expansion ROM memory allocations are no longer attempted by
default when the BIOS has not assigned a specific address range to the
expansion ROM BAR.  This was done by changing the 'pci=rom' boot option
behavior for BIOS unassigned expansion ROMs to actually match it's
current kernel-parameters.txt description which already implies "off" by
default. Behavior for BIOS assigned expansion ROMs implemented in
pcibios_assign_resources() [arch/x86/pci/i386.c] is unchanged.
