Following "mac80211: fix TX sequence numbers", if a packet
has the IEEE80211_TX_CTL_ASSIGN_SEQ assigned, a sequence number must be
supplied, either by hardware or software. AFAIK, no such hardware exists
for the p54, thus it must be done in software. With this patch, a connection
qith p54usb is stable, whereas the interface went off-line in 2-3 hours
without this change. Note that this code will have to be reworked for proper
sequence numbers on beacons. In addition, the sequence number has been placed
in the hardware state, not the vif state.

It is wrong to destroy a bonding master from a context that uses the sysfs
of that bond. When last IPoIB slave is unenslaved from by writing to a
sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves)
the driver tries to destroy the bond. This is wrong and can lead to a
lockup or a crash. This fix lets the bonding master stay and relies on
the user to destroy the bonding master if necessary (i.e. before module
ib_ipoib is unloaded)
This patch affects only bonds of IPoIB slaves. Ethernet slaves stay
unaffected.

Refactor mii monitor. As with the previous ARP monitor refactor,
the motivation for this is to handle locking rationally (in this case,
removing conditional locking) and generally clean up the code.
This patch breaks up the monolithic mii monitor into two phases:
an inspection phase, followed by an optional commit phase. The commit phase
is the only portion that requires RTNL or makes changes to state, and is
only called when inspection finds something to change.

Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
it will broken upper layer handle for promisc and allmulti.
In addition, drivers can use their own hardware programming to make it.
So do not allow drivers to set IFF_* flags.
This is a general driver fix, so I didn't split it to pieces and send
to specific driver maintainers.

The L1 hardware contains a bug that flags a fragmented IP packet
as having an incorrect TCP/UDP checksum, even though the packet
is perfectly valid and its checksum is correct. There's no way to
distinguish between one of these good packets and a packet that
actually contains a TCP/UDP checksum error, so all we can do is
allow the packet to be handed up to the higher layers and let it
be sorted out there.
Add a comment describing this condition and remove the code that
currently fails to handle what may or may not be a checksum error.

I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.

The benefits of a user settable CONFIG_IDE_MAX_HWIFS have become pretty
tiny and are no longer considered worth the trouble of an own option.
Simply always #define MAX_HWIFS to 10.

The guilty commit turned out to be 08da591e14
("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.
Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.
v2:
Brown paper bag time. In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in
the local variable (fix other device drivers too).

Fix byte-swapping for id->words161_175[], id->words206_254[]
and id->words206_254[].
Luckily all words previously left in little-endian byte-order
are marked as reserved so this fix shouldn't affect user-space
applications.

id->tDMA is of 'unsigned char' type so endianness is already
correct and calling le16_to_cpu() is wrong.

This patch fixes the 'scheduling while atomic' errors introduced by
commit 12dac0756d ("tg3: adapt tg3 to
use reworked PCI PM code").
The first hunk of the patch removes an unnecessary
tg3_set_power_state() call. The chip will already be in the D0 state
either due to a chip reset or through a previous call to
tg3_set_power_state().
The second hunk of the patch moves the tg3_set_power_state() call
outside the critical section guarded by tg3_full_lock() and
tg3_full_unlock() functions. The power state of the device is and
should be outside the lock's domain and all other
tg3_set_power_state() calls support this.

Converting page lock to new locking bitops requires a change of page flag
operation naming, so we might as well convert it to something nicer
(!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked).
This also facilitates lockdeping of page lock.

2.6.26 corrected the mutex locking on tty resizing to fix the case where
you could get the tty/vt sizing out of sync. That turns out to have a
deadlock.
The actual fix is really major and I've got it lined up as part of the ops
changes for 2.6.28 so for 2.6.26/2.6.27 it is safer to reintroduce this
ages old minor bug.
