The patch titled
pci: don't move ioapics below PCI bridge
has been removed from the -mm tree. Its filename is
pci-dont-move-ioapics-below-pci-bridge.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.

Subject: pci: don't move ioapics below PCI bridge
From: Kimball Murray <kimball.murray@xxxxxxxxx>
A recent Stratus x86_64 platform uses a system ioapic that is a PCI device
located below a PCI bridge. Other platforms like this may exist.
This patch fixes a problem wherein the kernel's PCI setup code moves the
ioapic to an address other than that assigned by the BIOS. It simply adds
another exclusion (which already includes classless devices and host
bridges) to the function pbus_assign_resources_sorted so that it will not
move the ioapic.
If the ioapic is moved, the fixmap mapping to it is broken, so the OS should
leave it alone.
