This patch fixes a couple of bugs and compile errors in the powerbook
media bay driver.  It was getting initialized after the IDE subsystem,
whereas it needs to be initialized before so that the IDE subsystem
can see the CD-ROM drive in the bay.

This patch updates the mac53c94 scsi HBA driver, used on older
powermacs, to correspond with the recent scsi subsystem changes, to
use the PCI DMA API, to not panic, and to use a spinlock instead of
save_flags/restore_flags/cli/sti.

This patch updates the `mesh' scsi driver used on older powermacs to
correspond with recent changes in the scsi subsystem (things like
using cmd->device->id instead of cmd->target).

This patch forward-ports various fixes to the driver for the PMU
(power manager unit) on powermacs and powerbooks from 2.4, and in
particular, some improvements to the battery charge calculations.

From Ben Herrenschmidt.

The patch below removes the uses of save_flags/restore_flags/cli
etc. from the macserial driver and replaces them with a spinlock.

This patch updates the CUDA driver (the power/reset/ADB controller on
older powermacs) to fix some SMP issues and to match the 2.4 version
of the driver.

From Ben Herrenschmidt.

This patch updates include/linux/adb.h and include/linux/pmu.h with
some additional definitions that we need on powermacs and powerbooks.

Convert the pcnet_cs driver to use the new registration call.

Remove the linked list of pcmcia_drivers. It didn't even handle removal of a
driver properly, so it won't be missed all that much.

Register all pcmcia drivers with the pcmcia bus within the old
register_pccard_driver() function. Alternatively, a new
registration function "pcmcia_register_driver()" (and its
counterpart,  "pcmcia_unregister_driver()") can be used.

Register a bus_type pcmcia_bus_type. This means the initialization of
the ds module needs to be done in two levels: one quite early
(subsys_initcall) so that drivers may use the bus_type; the other one
must stay that late (late_initcall). As only one initcall can be
specified within one module, some tweaking is needed.

Since it gets 1 device right it wasnt hard to fix 8)

I'm looking into the other IDE problem from the merge - several people
see hangs. Bartolomiej has found one suspicious looking candidate. I'll
try and pin it down ASAP.

- Redo the timing stuff using jiffies properly
- Clean up the exit paths
- Make the ioctl use a semaphore
- Fix broken locking on the AEN list

Two problems with the original change

1. We should return bytes actually processed on an error according to
SuS/POSIX. Technically the EFAULT path is outside the spec but its best
we follow

2. We need to fix most of this anyway because the final section of the
change was wrong. If retval was set we retried and got an efault again
in some cases

I think this way of doing it is right but it could do with further
review

* Increase default Rx descriptors from 80 to 256 to give
  better Rx buffering capability in the case of heavy
  Rx load with small packets.
