Stanse found that one error path (when alloc_skb fails) in netdev_tx
omits to unlock hw_priv->hwlock. Fix that by moving away from unlock in
each fail path. Unlock at one place instead.

As the PCI irq pin of the ti1130 pcmcia bridge is not connected (at
least on some old IBM Thinkpad 760ED notebooks), the Cardbus IRQ has
to be routed to an ISA irq.

Part 3 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

cb_irq is presumed to be the same as the pci_dev's irq. This won't be
true any more as soon as we allow the ISA irq to be used for Cardbus
devices. Therefore, use the pci_dev's irq explicitely whenever we
care about it.

Part 2 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

Instead of overwriting the I365_CSCINT register, save the old value and
merely change the bits we care about.

A newly added parent resource entry for the root PCI bus, such as

40000000-ffffffff : PCI Bus #00

means that the pd6729 and i82092 drivers cannot allocate iomem as
freely as before, unless they do so as PCI devices. Therefore, set
socket->cb_dev so that rsrc_nonstatic.c does the right thing.

Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.

To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.

Detect if a processor is physically present before evaluating _PDC.

We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.

We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.

Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.

I pulled them into Linux-2.6 on 2003-08-09.
Over the last 6+ years, several entries have proven to be
