The Via VT3351 APIC does not play well with MSI and unleashes a flood
of APIC errors when MSI is used to deliver interrupts. The problem
was recently exposed when the atl1 network device driver, which enables
MSI by default, stimulated APIC errors on an Asus M2V mainboard, which
employs the Via VT3351.
See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional
details on this bug.

pci_find_present() is only matching the last item in the list of ids.
The break after the match is found only escapes the for loop, not the
while loop, so found gets reset to NULL on the next pass.

I've been seeing lots of messages like these:
eth0: No interrupt was generated using MSI, switching to INTx mode. Please
report this failure to the PCI maintainer and include system chipset
information.
On several systems that use the following Severworks HT1000 (also sometimes
labeled as a Broadcom chipset as well) bridge chips. It doesn't appear MSI
works well (if at all) on these systems.

Deregister ccw device when device failure is detected during offline-
processing (e.g. when no last-path-gone indication was presented by
the hardware) to prevent the device from entering a non-recoverable
not-operational state.

Fix enable_irq_wake and disable_irq_wake symmetry in at91 pcmcia driver
disable_irq_wake call must be symmetric with enable_irq_wake. This patch
fix that problem for the at91_pcmia driver. It seems that this patch was
forgotten when we've fixed irq_wake symmetry in all at91 related drivers.
It was discussed in the "at91 drivers and [enable/disable]_irq_wake
(wrong?) usage" thread on the linux-arm-kernel mailing list.

This restores the previously removed netif_poll_enable call in e1000_open.
It's needed on all but the first call to e1000_open for a NIC as
e1000_close always calls netif_poll_disable.
netif_poll_enable can only be called safely if no polls have been
scheduled. This should be the case as long as we don't enter our IRQ
handler.
In order to guarantee this we explicitly disable IRQs as early as possible
when we're probing the NIC.
