Found a subtle bug that caused mount errors on a SATA drive with
barriers on reiser and ext3, where it should have recovered and just
turned off barriers. The problem is that the EOPNOTSUPP error isn't
being propagated properly to the bounced bio. This patch fixes that by
correctly passing error all the way down.

This patch is from Will Schmidt <willschm@us.ibm.com>, with some extra
comments from me.

On iSeries and on POWER5 machines, there is a data structure which is
used for communication between the hypervisor and the kernel, called
the `lppaca'.  The kernel tells the hypervisor where it is, and the
hypervisor requires that it doesn't cross a page boundary.  With other
changes in the last few months we have ended up with a situation where
it could cross a page boundary.  This patch increases the alignment
requirement for the struct to make sure that it can't cross a page
boundary.

This is a bug fix and should go into 2.6.10.

When we issue an ide command the status bits don't become valid for
400nS. In the DMA case ide_execute_command handles this but in the PIO
case we don't do the needed locking, use OUTBSYNC to avoid posting or
delay. This means that in some situations we can execute the command
handler in PIO mode before the command status bits are valid and the
handler may read and act wrongly.

It's a purely theoretical bug, since the kmalloc() failure that
might "leak" file descriptors cannot actually happen (we do not
ever fail small GFP_KERNEL allocations), but it's good to do
things properly.

This patch provides a new "sl811-hcd" driver, which should replace the older
one from Cypress (which has been broken for ages, even on SA-1100).

Key features of this new driver:

 - Small, relatively tight code;
 - Uses the 2.6 platform_device and usbcore HCD infrastructures;
 - Compiles (x86, ARM) and works (ARM/PXA255);
 - Passed a day's worth of "usbtest" stress testing (on 2.6.9).

I've enumerated over a dozen different devices with it, and actually tested
mice, hubs, keyboards, and usb-storage.  There's a hardware erratum that
prevents this chip from working with certain external hubs.  There's scope
yet for some performance work here; and some IRQ quirks linger.

This PIO-only driver should serve as a model for some other non-DMA USB host
controllers (like isp1161, isp1362, td243) used in embedded Linuxes ... in
particular, showing how to maintain async and periodic schedules without
pointless emulation of OHCI DMA queues and/or registers.

The driver should handle ISO, but since it doesn't implement the special
urb->iso_frame_desc[] "pseudo-queue" model (and since Linux can't guarantee
low enough IRQ latencies!), ISO is disabled.

I noticed an SMP deadlock when connecting devices to
an autosuspended root hub.

This fix just makes the OHCI hub status reporting logic (used
exclusively by khubd) be a NOP until after the worker task
(keventd) finishes resuming the port, so they can't deadlock.
