Per the PCI Firmware spec, r3.0, sec 4.5.1, on ACPI systems, the OS must
not use AER unless _OSC is present and _OSC grants AER control to the OS.
The aerdriver.forceload kernel parameter was a way to enable Linux AER
support on ACPI systems that lack _OSC or fail to grant control the the OS.Enabling Linux AER support when the firmware doesn't want us to is a recipe
for problems, e.g., the firmware might be handling AER itself.Remove the aerdriver.forceload kernel parameter and related supporting
code.Signed-off-by: Bjorn Helgaas

The aerdriver.nosourceid kernel parameter was intended for working around
broken chipsets don't supply the source ID for AER events. We recently
added PCI_BUS_FLAGS_NO_AERSID, which can be set by quirks for the same
purpose.Remove the aerdriver.nosourceid kernel parameter. For anything other than
debugging, asking users to find and use kernel parameters is a poor user
experience. Instead, we should add PCI_BUS_FLAGS_NO_AERSID quirks for any
hardware that needs it.Signed-off-by: Bjorn Helgaas

I noticed that when I inject a fatal error to an endpoint via
aer-inject, aer_root_reset() is called as reset_link for a
downstream port at upstream of the endpoint:pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401
:
pcieport 0000:52:02.0: Root Port link has been resetIt externally appears to be working, but internally issues some
accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for
root port so not available on downstream port.This patch introduces default_downstream_reset_link that is
a version of aer_root_reset() with no accesses to root port's
register. It is used for downstream ports that has no reset_link
function its specific.This patch also updates related description in pcieaer-howto.txt.
Some minor fixes are included.Signed-off-by: Hidetoshi Seto

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.Signed-off-by: Huang Ying

When the bus id part of error source id is equal to 0 or nosourceid=1,
make the kernel probe the AER status registers of all devices under the
root port to find the initial error reporter.Reviewed-by: Andrew Patterson

The 'use pci_find_ext_capability everywhere' cleanup brought a new bug,
which makes the AER stop working. Fix it by actually using find_ext_cap
instead of just find_cap. Drop the unused config space size define while
we're at it.Signed-off-by: Yu Zhao
