Debugging PCIE AER code can be very difficult because it is hard to
trigger various real hardware errors. This patch provide a software
based error injection tool, which can fake various PCIE errors with a
user space helper tool named "aer-inject". Which can be gotten from:
http://www.kernel.org/pub/linux/kernel/people/yhuang/
The patch fakes AER error by faking some PCIE AER related registers
and an AER interrupt for specified the PCIE device.
