When scheduled swaps occur, we need to blit between front & back
buffers. If the buffers are tiled, we need to set the appropriate
XY_SRC_COPY tile bit, but only on 965 chips, since it will cause
corruption on pre-965 (e.g. 945).

This patch fixes monitor mode operation for iwlwifi.
Problems addressed:
1. when monitor mode was enabled, multiple, overlapped calls were being
made to 'iwl3945_bg_set_monitor'
2. when monitor mode was disabled (via the configure_filter callback),
the driver was still enabling monitor mode
3. when monitor mode was enabled, the selected channel was not set
(eg. 'iwconfig wlanx mode monitor channel n' DID NOT SET channel 'n'

During the development of the physical PCI slot patch series, Gary Hade
kept on reporting strange oopses due to interactions between pci_slot
and acpiphp.
http://lkml.org/lkml/2007/11/28/319
find_root_bridges() unconditionally installs
handle_hotplug_event_bridge() as an ACPI_SYSTEM_NOTIFY handler for all
root bridges.
However, during module cleanup, remove_bridge() will only remove the
notify handler iff the root bridge had a hot-pluggable slot directly
underneath. That is:
root bridge -> hotplug slot
But, if the topology looks like either of the following:
root bridge -> non-hotplug slot
root bridge -> p2p bridge -> hotplug slot
Then we currently do not remove the notify handler from that root
bridge.
This can cause a kernel oops if we modprobe acpiphp later and it gets
loaded somewhere else in memory. If the root bridge then receives a
hotplug event, it will then attempt to call a stale, non-existent notify
handler and we blow up.
Much thanks goes to Gary Hade for his persistent debugging efforts.

For Broadcom 5706, 5708, 5709 rev. A nics, any read beyond the
VPD end tag will hang the device. This problem was initially
observed when a vpd entry was created in sysfs
('/sys/bus/pci/devices/<id>/vpd'). A read to this sysfs entry
will dump 32k of data. Reading a full 32k will cause an access
beyond the VPD end tag causing the device to hang. Once the device
is hung, the bnx2 driver will not be able to reset the device.
We believe that it is legal to read beyond the end tag and
therefore the solution is to limit the read/write length.
A majority of this patch is from Matthew Wilcox who gave code for
reworking the PCI vpd size information. A PCI quirk added for the
Broadcom NIC's to limit the read/write's.

The iwlwifi drivers go to great lengths to avoid passing packets to

Especially in the case of duplicate packets this is interesting

This patch is the minimal amount of code needed to support
wake-on-lan in platform mode properly (i.e. "ethtool -s eth0 wol g"
is sufficient, no additional magic needed) for me.
This is derived from David Brownells patch
(http://lists.laptop.org/pipermail/devel/2007-April/004691.html).
However I decided to move the hook into pci-acpi.c since the other
two pci hooks also live there and pci and acpi are the only users of
the platform_enable_wakeup-hook.
As a 'side-effect' this also makes wake on usb activity work for me
and I had to disable usb wakeup (which is enabled by default) using
the power/wakeup sysfs functionality ("echo disabled >
${sysfs_path_to_device}/power/wakeup").
(BTW I first thought the 'immediate reboot because of usb wake' effect is
caused by the optical mouse generating a wake event, but it rather
seems to be a problem with a flaky secondary usb host controller,
which sees a connected device where nothing is attached)

Without this device_can_wakeup and device_may_wakeup will return

Together with the minimized acpi wakeup patch (6/4 ;)), which will
follow in the next mail, this really makes wake-on-lan work for me

The call to e1000_clean_tx_irq in e1000_netpoll can race with the call
to e1000_clean_tx_irq in e1000_clean. With a small bit of tweaking to
to netpoll_send_skb to simulate a system that was under extreme stress,
I was able to reproduce these concurrent calls. This can result in
multiple frees to the skbs on the tx ring buffer.
Dropping this call from e1000_netpoll should be fine since we can rely
on the calls in e1000_clean to do what is needed since napi will poll
the hardware just after calling poll_controller.

I got a problem when I wanted to check if the kernel supports process
event connector, and It seems there's no way to do this check.
At best I can check if the kernel supports connector or not, by looking
into /proc/net/netlink, or maybe checking the return value of bind() to
see if it's ENOENT.
So it would be useful to add /proc/net/connector to list all supported
connectors:
# cat /proc/net/connector
Name ID
connector 4294967295:4294967295
cn_proc 1:1
w1 3:1

md_probe can fail (e.g. alloc_disk could fail) without
returning an error (as it alway returns NULL).
So when we call mddev_find immediately afterwards, we need
to check that md_probe actually succeeded. This means checking
that mdev->gendisk is non-NULL.

We shouldn't acknowledge that a stripe has been expanded (When
reshaping a raid5 by adding a device) until the moved data has
actually been written out. However we are currently
acknowledging (by calling md_done_sync) when the POST_XOR
is complete and before the write.
So track in s.locked whether there are pending writes, and don't
call md_done_sync yet if there are.
Note: we all set R5_LOCKED on devices which are are about to
read from. This probably isn't technically necessary, but is
usually done when writing a block, and justifies the use of
s.locked here.
This bug can lead to a crash if an array is stopped while an reshape
is in progress.

If, while assembling an array, we find a device which is not fully
in-sync with the array, it is important to set the "fullsync" flags.
This is an exact analog to the setting of this flag in hot_add_disk
methods.
Currently, only v1.x metadata supports having devices in an array
which are not fully in-sync (it keep track of how in sync they are).
The 'fullsync' flag only makes a difference when a write-intent bitmap
is being used. In this case it tells recovery to ignore the bitmap
and recovery all blocks.
This fix is already in place for raid1, but not raid5/6 or raid10.
So without this fix, a raid1 ir raid4/5/6 array with version 1.x
metadata and a write intent bitmaps, that is stopped in the middle
of a recovery, will appear to complete the recovery instantly
after it is reassembled, but the recovery will not be correct.
If you might have an array like that, issueing
echo repair > /sys/block/mdXX/md/sync_action
will make sure recovery completes properly.

This fixes a circular locking dependency in the workqueue handling.
The interface work task uses the mac80211 function
ieee80211_iterate_active_interfaces() which grabs the RTNL lock.
However when the interface is brough down, this happens under the RTNL
lock as well, this causes problems because mac80211 will flush the workqueue
during the ifdown event. This causes mac80211 to wait until the driver has
completed all work which can't finish because it is waiting on the RTNL lock.
This is fixed by moving rt2x00 workqueue tasks on a different workqueue,
this workqueue can be flushed when the ieee80211_hw structure is removed
by the driver (when the driver is unloaded) which does not happen under the
RTNL lock.

When rt2x00queue_alloc_rxskbs() fails rt2x00queue_unitialize()
will be called which will free all rxskb. So we don't need
to do this in the rt2x00queue_alloc_rxskb() function as well.
rt2x00queue_free_skb() unmaps the DMA but doesn't clear the
allocation flag. Since the code is copied from rt2x00queue_unmap_skb()
anyway (and that function does clear the flag) we might as well
use that function directly.

s2io has IOMMU overflow checking, but unfortunately it is wrong.
It didn't use the standard macros, which meant that it only worked
on POWER and SPARC because only those define DMA_ERROR_CODE. Convert it to
use the standard macros instead.
I also commented two more bugs in the IOMMU handling. It assumes
that 0 DMA addresses cannot happen, but that's not true in all IOMMU setups.
The information if a buffer has been already mapped needs to be stored
elsewhere.
Didn't fix those because it needs careful checking of the buffer handling
by the maintainers.
