Claim devices using PNP, unless the user explicitly specified device
addresses. This can be disabled with the "smsc-ircc2.nopnp" option.
This removes the need for probing legacy addresses and helps untangle IR
devices from serial8250 devices.
Sometimes the SMC device is at a legacy COM port address but does not use the
legacy COM IRQ. In this case, claiming the device using PNP rather than 8250
legacy probe means we can automatically use the correct IRQ rather than
forcing the user to use "setserial" to set the IRQ manually.
If the PNP claim doesn't work, make sure you don't have a setserial init
script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port
resources for the IRDA device. That causes the serial driver to claim
resources needed by this driver.

Spurious interrupts are often encountered especially on systems
using the 8259 PIC mode. This is because the I/O write to deassert
the interrupt is posted and won't get to the chip immediately. As
a result, the IRQ may remain asserted after the IRQ handler exits,
causing spurious interrupts.
Flush the interrupt mailbox in non-MSI handlers to de-assert the
IRQ immediately. This seems to be the most straight forward approach
after discussion with Jeff Garzik and David Miller.

The reset was added a while back so that ASF could re-init whatever
MAC address it wanted to use after the MAC address was changed.
Instead of resetting, we can just keep MAC address 1 unchanged during
MAC address changes if MAC address 1 is different from MAC address 0.
This fixes 2 problems:
1. Bonding calls set_mac_address in contexts that cannot sleep.
It no longer sleeps with the chip reset removed.
2. When ASF shares the same MAC address as the NIC, it needs to
always do that even when the MAC address is changed.

is useful in cases where the traditional NVRAM sizing method fails. In
the event that the flash size cannot be determined, the largest known
NVRAM size is used. The patch also removes support for 5755 NVRAM

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:
