For some unknown reason ELP_CTRL can't be accesed using
sdio_memcpy_* functions (any attemts to do so result in timeouts):
wl1251: ERROR sdio write failed (-110)
wl1251: ERROR sdio read failed (-110)
wl1251: WARNING WLAN not ready
To fix this, add special IO functions for ELP_CTRL access that are
using sdio_readb/sdio_writeb. Similar handling is done in TI
reference driver from Android code drop.

As the PCI irq pin of the ti1130 pcmcia bridge is not connected (at

to be routed to an ISA irq.

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.

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.

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.

acpi=ht was important in 2003 -- before ACPI was
universally deployed and enabled by default in
the major Linux distributions.
At that time, there were a fair number of people who
or chose to, or needed to, run with acpi=off,
yet also wanted access to Hyper-threading.
Today we find that many invocations of "acpi=ht"
are accidental, and thus is it possible that it
is doing more harm than good.
In 2.6.34, we warn on invocation of acpi=ht.
In 2.6.35, we delete the boot option.
