x86, 32-bit: Align percpu area and irq stacks to THREAD_SIZE
The irq stacks, located in the percpu-area, need to be
THREAD_SIZE aligned. Add the infrastucture to align percpu
variables to larger-than-pagesize amounts within the percpu
area, and use it to specify the alignment for the irq stacks.
Also align the percpu area itself to THREAD_SIZE.
This should make irq stacks work with 8K THREAD_SIZE.

x86: Always use irq stacks
IRQ stacks provide much better safety against unexpected stack use from
interrupts, at the minimal downside of slightly higher memory usage.
Enable irq stacks also for the default 8k stack on 32-bit kernels to
minimize the problem of stack overflows through interrupt activity.
This is what the 64-bit kernel and various other architectures already do.

There are few situations where it would make any sense to add a spare
when reducing the number of devices in an array, but it is
conceivable: A 6 drive RAID6 with two missing devices could be
reshaped to a 5 drive RAID6, and a spare could become available

do without any races.
However doing such a thing is a bad idea. md will not record the

Easiest way to avoid this confusion is to simply disallow it.

When we are reshaping an array, the device failure combinations
that cause us to decide that the array as failed are more subtle.
In particular, any 'spare' will be fully in-sync in the section
of the array that has already been reshaped, thus failures that
affect only that section are less critical.
So encode this subtlety in a new function and call it as appropriate.
The case that showed this problem was a 4 drive RAID5 to 8 drive RAID6
conversion where the last two devices failed.
This resulted in:
good good good good incomplete good good failed failed
while converting a 5-drive RAID6 to 8 drive RAID5
The incomplete device causes the whole array to look bad,
bad as it was actually good for the section that had been
converted to 8-drives, all the data was actually safe.

md: Don't update ->recovery_offset when reshaping an array to fewer devices.
When an array is reshaped to have fewer devices, the reshape proceeds
from the end of the devices to the beginning.
If a device happens to be non-In_sync (which is possible but rare)
we would normally update the ->recovery_offset as the reshape
progresses. However that would be wrong as the recover_offset records
that the early part of the device is in_sync, while in fact it would
only be the later part that is in_sync, and in any case the offset
number would be measured from the wrong end of the device.
Relatedly, if after a reshape a spare is discovered to not be
recoverred all the way to the end, not allow spare_active
to incorporate it in the array.
This becomes relevant in the following sample scenario:
A 4 drive RAID5 is converted to a 6 drive RAID6 in a combined
operation.
The RAID5->RAID6 conversion will cause a 5 drive to be included as a
spare, then the 5drive -> 6drive reshape will effectively rebuild that
spare as it progresses. The 6th drive is treated as in_sync the whole
time as there is never any case that we might consider reading from
it, but must not because there is no valid data.
If we interrupt this reshape part-way through and reverse it to return
to a 5-drive RAID6 (or event a 4-drive RAID5), we don't want to update
the recovery_offset - as that would be wrong - and we don't want to
include that spare as active in the 5-drive RAID6 when the reversed
reshape completed and it will be mostly out-of-sync still.

md: fix handling of array level takeover that re-arranges devices.
Most array level changes leave the list of devices largely unchanged,
possibly causing one at the end to become redundant.
However conversions between RAID0 and RAID10 need to renumber
all devices (except 0).
This renumbering is currently being done in the ->run method when the
new personality takes over. However this is too late as the common
code in md.c might already have invalidated some of the devices if
they had a ->raid_disk number that appeared to high.
Moving it into the ->takeover method is too early as the array is
still active at that time and wrong ->raid_disk numbers could cause
confusion.
So add a ->new_raid_disk field to mdk_rdev_s and use it to communicate
the new raid_disk number.
Now the common code knows exactly which devices need to be renumbered,
and which can be invalidated, and can do it all at a convenient time
when the array is suspend.
It can also update some symlinks in sysfs which previously were not be
updated correctly.

when the device is not yet open, bdev->bd_disk won't be set, so the
flush_disk() Call will not set bd_invalidated.
So when md_open is called we still need to ensure that
->bd_invalidated gets set. This is easily done with a call to
check_disk_size_change in the place where the offending commit removed
check_disk_change. At the important times, the size will have changed

SUNRPC: Fix a re-entrancy bug in xs_tcp_read_calldir()
If the attempt to read the calldir fails, then instead of storing the read

hso: remove setting of low_latency flag
This patch removes the setting of the low_latency flag.
tty_flip_buffer_push() is occasionally being called in irq context, which
causes a hang if the low_latency flag is set.
Removing the low_latency flag only seems to impact the flush to ldisc,
which will now be put on a workqueue.

udp: Fix bogus UFO packet generation
It has been reported that the new UFO software fallback path
fails under certain conditions with NFS. I tracked the problem
down to the generation of UFO packets that are smaller than the
MTU. The software fallback path simply discards these packets.
This patch fixes the problem by not generating such packets on
the UFO path.

Stanse found that in snd_usb_parse_audio_endpoints, there is a
