Now we have vlan_vids_add/del_by_dev() which serve the same purpose as
bond's bond_add/del_vlans_on_slave() with the good side effect of
reverting the changes if one of the additions fails.
There's only 1 change in the behaviour of enslave: if adding of the
vlans to the slave fails, we'll fail the enslaving because otherwise we
might delete some vlan that wasn't added by the bonding.
The only way this may happen is with ENOMEM currently, so we're in trouble
anyway.

With GRO/LRO processing, there is a problem because Ip[6]InReceives SNMP
counters do not count the number of frames, but number of aggregated
segments.
Its probably too late to change this now.
This patch adds four new counters, tracking number of frames, regardless
of LRO/GRO, and on a per ECN status basis, for IPv4 and IPv6.
Ip[6]NoECTPkts : Number of packets received with NOECT
Ip[6]ECT1Pkts : Number of packets received with ECT(1)
Ip[6]ECT0Pkts : Number of packets received with ECT(0)

Commit 5688978 ("ext4: improve handling of conflicting mount options")
introduced incorrect messages shown while choosing wrong mount options.
First of all, both cases of incorrect mount options,
"data=journal,delalloc" and "data=journal,dioread_nolock" result in
the same error message.
Secondly, the problem above isn't solved for remount option: the
mismatched parameter is simply ignored. Moreover, ext4_msg states
that remount with options "data=journal,delalloc" succeeded, which is
not true.
To fix it up, I added a simple check after parse_options() call to
ensure that data=journal and delalloc/dioread_nolock parameters are
not present at the same time.

Commit 26092bf ("ext4: use a table-driven handler for mount options")
wrongly disallows the specifying the mount options nodelalloc and

====================
This is a batch of fixes intended for the 3.11 queue...
Regarding the mac80211 (and related) bits, Johannes says:
"I have a fix from Chris for an infinite loop along with fixes from
myself to prevent it entering the loop to start with (continue using
disabled channels, many thanks to Chris for his debug/test help) and a
workaround for broken APs that advertise a bad HT primary channel in
their beacons. Additionally, a fix for another attrbuf race in mac80211
and a fix to clean up properly while P2P GO interfaces go down."
Along with that...
Solomon Peachy corrects a range check in cw1200 that would lead to
a BUG_ON when starting AP mode.
Stanislaw Gruszka provides an iwl4965 patch to power-up the device
earlier (avoiding microcode errors), and another iwl4965 fix that
resets the firmware after turning rfkill off (resolving a bug in the
Red Hat Bugzilla).

In adt7470_write_word_data(), which writes two bytes using
i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed
together when they should be OR-ed together.
The return code of i2c_smbus_write_byte_data() is zero for success.
The upshot is only the first byte was ever written to the hardware.
The 2nd byte was never written out.
I noticed that trying to set the fan speed limits was not working
correctly on my system. Setting the fan speed limits is the only
code that uses adt7470_write_word_data(). After making the change
the limit settings work and the alarms work also.

This reverts commit 318df36e57.
This commit caused Steven Rostedt's hackbench runs to run out of memory
due to a leak. As noted by Joonsoo Kim, it is buggy in the following
scenario:
"I guess, you may set 0 to all kmem caches's cpu_partial via sysfs,
doesn't it?
In this case, memory leak is possible in following case. Code flow of
possible leak is follwing case.
* in __slab_free()
1. (!new.inuse || !prior) && !was_frozen
2. !kmem_cache_debug && !prior
3. new.frozen = 1
4. after cmpxchg_double_slab, run the (!n) case with new.frozen=1
5. with this patch, put_cpu_partial() doesn't do anything,
because this cache's cpu_partial is 0
6. return
In step 5, leak occur"
And Steven does indeed have cpu_partial set to 0 due to RT testing.
Joonsoo is cooking up a patch, but everybody agrees that reverting this
for now is the right thing to do.

The driver used to assume that the streaming endpoint's wMaxPacketSize
value would be an indication of how much data the endpoint expects or
sends, and compute the number of packets per URB using this value.
However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes,
while only about 88 or 44 bytes are be actually used. This discrepancy
would result in URBs with far too few packets, which would not work
correctly on the EHCI driver.
To get correct URBs, use wMaxPacketSize only as an upper limit on the
packet size.

For r6xx+ asics. This mirrors the behavior of pre-r6xx
asics. We need to program the MC even if something
else in startup() fails. Failure to do so results in
an unusable GPU.

Need to set the wallclock ratio and adjust the phase
and module registers appropriately. May fix problems
with audio timing at certain display timings.
v2: properly handle clocks below 24mhz
v3: rebase r600 changes

Removing the clock/power or resetting the VCPU can cause
hangs if that happens in the middle of a register write.
Stall the memory and register bus before putting the VCPU
into reset. Keep it in reset when unloading the module or
suspending.

There are some hardware issue with reclocking on SI when
UVD is active, so use a stable power state when UVD is
active. Fixes possible hangs and performance issues when
using UVD on SI.

Need to check for engine and memory clock ss separately
and only enable dynamic ss if either of them are found.
This should fix systems which have a ss table, but do
not have entries for engine or memory. On those systems
we may enable dynamic spread spectrum without enabling
it on the engine or memory clocks which can lead to a
hang in some cases.
fixes some systems reported here:

On rv770 and newer, clock gating is not required
for thermal protection. The only requirement is that
the design utilizes a thermal sensor.

There are two audio dtos on radeon asics that you can
select between. Normally, dto0 is used for hdmi and
dto1 for DP, but it seems that the dto is somehow
tied to the encoders on DCE3 asics.

When we reset the GPU, we need to properly tear
down power management before reseting the GPU and then
set it back up again after reset. Add the missing
radeon_pm_[suspend|resume] calls to the gpu reset
function.
