From: Jan Kiszka <jan.kiszka@siemens.com>

Pulls in latest version from kernel 3.0-rc2.

Some changes around AER now require local defines as QEMU accesses the
error source identification register via sub-words.

I don't think the #define requirements of pcie_aer are upstream
compatible, therefore private constants.

This will allow to drop libpci build dependency from qemu-kvm.

pcie_aer.c change looks good.
Thanks.
