Values displayed when by cardctl config are horribly wrong for 16bit cards.
 this fixes it up by not using memcpy() since source and target struct are
very different.

The patch below cleans up the pcmcia code a bit on the IRQ side (I did
this while debugging the problem just so I could read wtf it was doing),
and also adds a warning and passes back the correct information when a
device asks for exclusive but gets given shared. This at least means the
dmesg dump of a problem triggered by this will have a signature to find.

Using the old ioctl interface together with cardbus card gives a NULL
pointer dereference since cardbus devices don't have a struct pcmcia_device.
also s->io[0].res can be NULL as well.

Fix is to move the pcmcia code after the cardbus code and to check for a null
pointer.

Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the

multifunction cards need to have the same irq assigned to both functions.
the code tries that but fails because ret is still set to CS_IN_USE which
results in the function having the CB irq assigned.  yenta_set_socket then
just changes the irq routing to use the PCI interrupt but the first
functions irq handler is registered on an ISA interrupt.  boom.

Debugging and description from: Noah Misch <noah@cs.caltech.edu>

When a driver calls pcmcia_request_irq with IRQ_HANDLE_PRESENT unset, it looks
for an open IRQ by request_irq()ing with a dummy handler and NULL dev_info.
free_irq uses dev_info as a key for identifying the handler to free among
those sharing an IRQ, so request_irq returns -EINVAL if dev_info is NULL and
the IRQ may be shared.  That unknown error code is the -EINVAL.

It looks like only pcnet_cs and axnet_cs are affected.  Most other drivers let
pcmcia_request_irq install their interrupt handlers.  sym53c500_cs requests
its IRQ manually, but it cannot share an IRQ.

The appended patch changes pcmcia_request_irq to pass an arbitrary, unique,
non-NULL dev_info with the dummy handler.

The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified.  Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.

For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes.  A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).

So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).
