Hi Linus,
These are two important regression fixes for bugs we've introduced so far
in v3.14.
One of the resource allocation changes from the merge window is broken for
32-bit kernels where we don't use _CRS for PCI host bridges (mostly
pre-2008 machines), so there's a fix for that.
The INTx enable change we put in after the merge window turned out to break
pciehp because we re-enable INTx on the hotplug bridge, which apparently
breaks MSI for future hotplug events.
The following changes since commit fa389e220254c69ffae0d403eac4146171062d08:
