This addresses an SMP-only issue with the EHCI driver, where only one CPU
should scan the schedule at a time (scanning is not re-entrant) but either
the IRQ handler or a watchdog timer could end up starting it.  Many thanks
to Olaf Hering for isolating the failure mode, and testing this fix!

Once once CPU starts scanning, any other might as well finish right
away.  This fix just adds a flag to detect that case.

The kernel keeps printing "Lost sync on frames" error messages as soon as a
program tries to access the webcam.  No video data can be retrieved from
the webcam.

The following patch seems enough to solve the problem.  (just inverting the
order at which the old and new data blocks are sent to the user).

Fixes a data corruption issue. Because of a typo in the driver, IO packets
were wrongly shared by the IOCTL path. This caused the whole IO command
to be replaced by an incoming IOCTL command.

ACPI still explodes on my old PII and stops it booting.

Anyway, it is oopsing in drivers/acpi/scan.c line 207 where element
(which is NULL) gets dereferenced.

The ACPI bios on this thing has always seemed to be pretty broken, but
this at least allows the 'power' button to continue to work (the only
reason why I want ACPI).

As spotted by one of our Fedora users, we sometimes
oops during shutdown (http://www.roberthancock.com/kerneloops.png)
because disable_IO_APIC() wants to call find_isa_irq_pin(),
which we threw away during init.

This is made possible by the previous resource allocation ordering
patch.

Now that we run the pre-existing PCI resource discovery _before_
ACPI resources have been added, we should not "insert" the resources
into any existing tree. If they clash with existing resources, we
should re-allocate them (later, when we have the full resource map).

This re-orders the PCI and ACPI IO resource assignment as suggested by
Linus.

With this patch, now the sequence of reserving resources is:
 1. PCI claim BAR
 2. ACPI reserve motherboard resources
 3. PNP reserve motherboard resources
 4. PCI allocate resources for uninitialized PCI devices

This way the kernel allocates new PCI resources after it has full
knowledge of the resource state, and at the same time allows ACPI and
PnP to be run _after_ we've filled in our knowledge about pre-allocated
resources. 

The way it is done is to make the last phase of the original PCI assign
resources code to be an 'fs_initcall', along with the ACPI and PnP
initializations.

The blacklist stuff is broken. When set_using_dma() calls into
->ide_dma_check(), it returns __ide_dma_off() for a blacklisted drive.
This of course succeeds, returning success to the caller of ->ide_dma_check().
Not so good... It then uncondtionally calls ->ide_dma_on(), which turns on
DMA for the drive.

This moves the check to __ide_dma_on() so we also catch the buggy
->ide_dma_check() defined by various chipset drivers.

Patch from Sascha Hauer

This patch supports the Hynix developer boards h7201 and h7202 for the
HMS30C7201 and HMS30C7202 CPUs.

Changes to previous patch:
- reorganized file structure. We now have common.c which shares stuff
  common to all h720x processors and cpu-h720[12].c files for the cpu
  specific stuff
- fixed timer handling for timers 1/2
- cleaned up h720x register definitions and splitted in files specific
  to each cpu and one generic part

The cpu mask fix-ups in 2.6.8 broke SMP kernels booting on a DP264.

inadvertently doesn't set the DIM for CPUs that do exist.  Thus no device
