If an incremental recovery was interrupted, a subsequent
re-add will result in a full recovery, even though an
incremental should be possible (seen with raid1).
Solve this problem by not updating the superblock on the
recovering device until array is not degraded any longer.

When we add a device to an active array it can be meaningful to set
the 'insync' flag. This indicates that the device is in-sync with the
array except for locations recorded in the bitmap.
A bitmap-based recovery can then bring it completely in-sync.
Internally we move that flag to 'saved_raid_disk' but forgot to clear
In_sync like we do in add_new_disk.
So clear In_sync after moving its value to saved_raid_disk.

Based on a patch from Michael Ellerman, clean up a significant

Even worse, we were always checksumming tx packets and ignoring the

The ehea adapter has a mode where it will avoid partial cacheline DMA
writes on receive by always padding packets to fall on a cacheline
boundary.
Unfortunately we currently aren't allocating enough space for a full
ethernet MTU packet to be rounded up, so this optimisation doesn't hit.
It's unfortunate that the next largest packet size exposed by the
hypervisor interface is 2kB, meaning our skb allocation comes out of a
4kB SLAB. However the performance increase due to this optimisation is
quite large and my TCP stream numbers increase from 900MB to 1000MB/sec.

The ehea driver had some multiqueue support but was missing the last
few years of networking stack improvements:
- Use skb_record_rx_queue to record which queue an skb came in on.
- Remove the driver specific netif_queue lock and use the networking
stack transmit lock instead.
- Remove the driver specific transmit queue hashing and use
skb_get_queue_mapping instead.
- Use netif_tx_{start|stop|wake}_queue where appropriate. We can also
remove pr->queue_stopped and just check the queue status directly.
- Print all 16 queues in the ethtool stats.
We now enable multiqueue by default since it is a clear win on all my
testing so far.

1) We move the AMT Watchdog to use the kernel watchdog core.
the new code is still part of the MEI driver.
we didn't find any good reason to extract the the MEI driver watchdog code
from the MEI Driver to a new module.
2) Since the watchdog remains in the mei driver, exposing in-kernel
API just for AMTHI is unnecessary.

Previously, the device-driver matching mechanism depended on the
vme_device_id structure due to the need for a bind table per driver.
This method of matching is no longer used so this patch merges the
fields of struct vme_device_id into struct vme_dev. Since this also
renders the slot field meaningless, it has also been removed in this
patch.

For jumper based boards (non VME64x), there is no mechanism
for detecting the card that is plugged into a specific slot. This
leads to issues in non-autodiscovery crates/cards when a card is
plugged into a slot that is "claimed" by a different driver. In
reality, there is no problem, but the driver rejects such a
configuration due to its dependence on the concept of slots.
This patch makes the concept of slots less critical and pushes the
driver match() to individual drivers (similar to what happens in the
ISA bus in driver/base/isa.c). This allows drivers to register the
number of devices that they expect without any restrictions. Devices
in this new model are now formatted as $driver_name-$bus_id.$device_id
(as compared to the earlier vme-$bus_id.$slot_number).
This model also makes the device model more logical as devices
are only registered when they actually exist whereas earlier,
a set of devices were being created automatically regardless of
them actually being there.
Another change introduced in this patch is that devices are now created
within the VME driver structure rather than in the VME bridge structure.
This way, things don't go haywire if the bridge driver is removed while
a driver is using it.

Instead of using a vanilla 'struct device' for VME devices, add new
'struct vme_dev'. Modifications have been made to the VME framework
API as well as all in-tree VME drivers.
The new vme_dev structure has the following advantages from the
current model used by the driver:
* Driver functions (probe, remove) now receive a VME device
instead of a pointer to the bridge device (cleaner design)
* It's easier to differenciate API calls as bridge-based or
device-based (ie. cleaner interface).

The documenation explaining how to go about writing a driver is lagging
horribly, so here is another approach; an actual driver with
lots of explanatory comments.
Note it is currently minimal in that there are no events and no
buffer. With care they can probably be added in additional files
without messing up the clarity of what we have here.

zcache_do_preload() currently does a spin_trylock() on the
zcache_direct_reclaim_lock. Holding this lock intends to prevent
shrink_zcache_memory() from evicting zbud pages as a result
of a preload.
However, it also prevents two threads from
executing zcache_do_preload() at the same time. The first
thread will obtain the lock and the second thread's spin_trylock()
will fail (an aborted preload) causing the page to be either lost
(cleancache) or pushed out to the swap device (frontswap). It
also doesn't ensure that the call to shrink_zcache_memory() is
on the same thread as the call to zcache_do_preload().
Additional, there is no need for this mechanism because all
zcache_do_preload() calls that come down from cleancache already
have PF_MEMALLOC set in the process flags which prevents
direct reclaim in the memory manager. If the zcache_do_preload()
call is done from the frontswap path, we _want_ reclaim to be
done (which it isn't right now).
This patch removes the zcache_direct_reclaim_lock and related
statistics in zcache.
