Add to help text that the Intel I2C ICH (i801) driver is also needed
for this kernel.
Add LEDS_CLASS to config since the driver makes les_classdev_*() calls:

This message describes another issue about md RAID10 found by testing the
2.6.24 md RAID10 using new scsi fault injection framework.
Abstract:
When a scsi error results in disabling a disk during RAID10 recovery, the
resync threads of md RAID10 could stall.
This case, the raid array has already been broken and it may not matter. But
I think stall is not preferable. If it occurs, even shutdown or reboot will
fail because of resource busy.
The deadlock mechanism:
The r10bio_s structure has a "remaining" member to keep track of BIOs yet to
be handled when recovering. The "remaining" counter is incremented when
building a BIO in sync_request() and is decremented when finish a BIO in
end_sync_write().
If building a BIO fails for some reasons in sync_request(), the "remaining"
should be decremented if it has already been incremented. I found a case
where this decrement is forgotten. This causes a md_do_sync() deadlock
because md_do_sync() waits for md_done_sync() called by end_sync_write(), but
end_sync_write() never calls md_done_sync() because of the "remaining" counter
mismatch.
For example, this problem would be reproduced in the following case:
Personalities : [raid10]
md0 : active raid10 sdf1[4] sde1[5](F) sdd1[2] sdc1[1] sdb1[6](F)
3919616 blocks 64K chunks 2 near-copies [4/2] [_UU_]
[>....................] recovery = 2.2% (45376/1959808) finish=0.7min speed=45376K/sec
This case, sdf1 is recovering, sdb1 and sde1 are disabled.
An additional error with detaching sdd will cause a deadlock.
md0 : active raid10 sdf1[4] sde1[5](F) sdd1[6](F) sdc1[1] sdb1[7](F)
3919616 blocks 64K chunks 2 near-copies [4/1] [_U__]
[=>...................] recovery = 5.0% (99520/1959808) finish=5.9min speed=5237K/sec

The resync thread keeps working, but actually it is deadlocked.

Thanks to K.Tanaka and the scsi fault injection framework, here is a fix for
another possible deadlock in raid1/raid10 error handing.
If a read request returns an error while a resync is happening and a resync
request is pending, the attempt to fix the error will block until the resync
progresses, and the resync will block until the read request completes. Thus
a deadlock.
This patch fixes the problem.

This patch changes the disk to be read for layout "far > 1" to always be the
disk with the lowest block address.
Thus the chunks to be read will always be (for a fully functioning array) from
the first band of stripes, and the raid will then work as a raid0 consisting
of the first band of stripes.
Some advantages:
The fastest part which is the outer sectors of the disks involved will be
used. The outer blocks of a disk may be as much as 100 % faster than the
inner blocks.
Average seek time will be smaller, as seeks will always be confined to the
first part of the disks.
Mixed disks with different performance characteristics will work better, as
they will work as raid0, the sequential read rate will be number of disks
involved times the IO rate of the slowest disk.
If a disk is malfunctioning, the first disk which is working, and has the
lowest block address for the logical block will be used.

When we access attributes of an rdev (component device on an md array) through
sysfs, we really need to lock the array against concurrent changes. We
currently do that when we change an attribute, but not when we read an
attribute. We need to lock when reading as well else rdev->mddev could become
NULL while we are accessing it.
So add appropriate locking (mddev_lock) to rdev_attr_show.
rdev_size_store requires some extra care as well as it needs to unlock the
mddev while scanning other mddevs for overlapping regions. We currently
assume that rdev->mddev will still be unchanged after the scan, but that
cannot be certain. So take a copy of rdev->mddev for use at the end of the
function.

A resync/reshape/recovery thread will refuse to progress when the array is
marked read-only. So whenever it mark it not read-only, it is important to
wake up thread resync thread. There is one place we didn't do this.
The problem manifests if the start_ro module parameters is set, and a raid5
array that is in the middle of a reshape (restripe) is started. The array
will initially be semi-read-only (meaning it acts like it is readonly until
the first write). So the reshape will not proceed.
On the first write, the array will become read-write, but the reshape will not
be started, and there is no event which will ever restart that thread.

On an md array with a write-intent bitmap, a thread wakes up every few seconds
and scans the bitmap looking for work to do. If the array is idle, there will
be no work to do, but a lot of scanning is done to discover this.
So cache the fact that the bitmap is completely clean, and avoid scanning the
whole bitmap when the cache is known to be clean.

When handling a read error, we freeze the array to stop any other IO while
attempting to over-write with correct data.
This is done in the raid1d(raid10d) thread and must wait for all submitted IO
to complete (except for requests that failed and are sitting in the retry
queue - these are counted in ->nr_queue and will stay there during a freeze).
However write requests need attention from raid1d as bitmap updates might be
required. This can cause a deadlock as raid1 is waiting for requests to
finish that themselves need attention from raid1d.
So we create a new function 'flush_pending_writes' to give that attention, and
call it in freeze_array to be sure that we aren't waiting on raid1d.

Workaround for the FT232RL-based, Matrix Orbital VK204-25-USB serial port
added to the ftdi_sio driver.
The device has an invalid endpoint descriptor, which must be modified
before it can be used.

This patch (as1037) makes a small update to the earlier as1035 patch.
The minimum-length computation shouldn't be done in
usb_stor_access_xfer_buf(), since that routine can be called multiple
times for a single transfer. It should be done in
usb_stor_set_xfer_buf() instead, which gets called only once.
The way it is now isn't really _wrong_, but it isn't really _right_
either. Moving the statement will be an improvement.

This patch removes the buffering of the status register.
USB core behavior has changed a bit and this buffering was not refreshed
at the right time. The core got buffered old value of HCRHPORT and it
did not detect any devices on boot.

USB: ehci: Fixes completion for multi-qtd URB the short read case
When use of urb->status in the EHCI driver was reworked last August
(commit 14c04c0f88f228fee1f412be91d6edcb935c78aa), a bug was inserted
in the handling of early completion for bulk transactions that need
more than one qTD (e.g. more than 20KB in one URB).
This patch resolves that problem by ensuring that the early completion
status is preserved until the URB is handed back to its submitter,
instead of resetting it after each qTD.

This patch (as1040) fixes up the blacklist of USB device quirks. A
couple of lines are broken to comply with the 80-column rule, and
entries are sorted into the proper numerical order.

This patch (as1039) updates the Kconfig entry for USB_SUSPEND. The
out-of-date reference to "power/state" is fixed, autosuspend is
mentioned, and the dependency on EXPERIMENTAL is removed.
