Paul Gortmaker says:
====================
The removal of wanrouter code was originally listed in the (now
gone) feature removal file since May 2012, and an RFC of the
deletion was posted[1] in late 2012. The overall concept was given
an OK, but defconfig contamination, build failures, etc. meant that
it didn't quite make it into mainline for 3.8.
Since that time, Dan discovered (via code audit) a runtime bug that
proves nobody has been using this for over four years[2]. With that
new information, I think it makes sense for someone to follow through
on Joe's original RFC and get this done for the 3.9 release.
In addition to resolving the build failures of the RFC by keeping
stub headers, this also splits the change into two parts, just like
the token ring removal did. Part #1 decouples the mainline kernel
from the expired subsystem, and part #2 does the large scale
deletion of the subsystem content.
The advantage of the above, is that a "git blame" will never lead
you to a 4000+ line deletion commit. The large scale deletion will
never show up in a "git blame" and hence the same advantages that we
get from the "--irreversible-delete" in the review stage of "git
format-patch" are also embedded into the git history itself. This
may seem like a moot point to some, but for those who spend a
considerable amount of time data mining in the git history, this is
probably worth doing.
I have done build tests of all[mod/yes]config for both the stage 1
(Makefile and Kconfig) and stage 2 (full driver delete) as a sanity
check, and the issues with the previously posted RFC should be gone.
Speaking of "--irreversible-delete" -- these patches were created
with that option, so if you want to use them locally, you are going
to have to pull (location below) the content instead of doing a
"git am" of the mailed out content.

The loop looking for correct mount option entry is more logical if it is
written rewritten as an empty loop looking for correct option entry and then
code handling the option. It also saves one level of indentation for a lot of

We actually store the MAC address as well as the board_name here. The
longest board_name is 75 characters so there is more than enough room
to hold the 17 character MAC and the ": " divider. But making this

====================
This series contains updates to ixgbe and e1000e. The ixgbe patches are
a mix of fixes, cleanup and added functionality. The first fix is for
traffic classes, where if the mapping has changed reset the NIC. The other
ixgbe fix resolves an issue where the device lookup neglected to do a
pci_dev_put() to decrement the device reference count.
The ixgbe cleanup was done by Josh, where the auto-negotiation variables
were renamed/cleaned up and refactored.
The remaining patches are from Bruce to do additional cleanup on e1000e as
well as bump the driver version. Most notably is the cleanup to use the
kernel IEEE MII definitions where possible instead of the local MII
definitions.

Pull a huge ab8500/pm2301 pile of changes from Lee Jones. Lee did an

Power supply subsystem creates thermal zone device for the property
'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready
before 'ab8500 battery temperature monitor' driver is initialized. ab8500
btemp driver is initialized with subsys_initcall whereas thermal subsystem
is initialized with fs_initcall which causes
thermal_zone_device_register(...) to crash since the required structure
'thermal_class' is not initialized yet:

Now companion ACPI devices are always created before corresponding

handle bridge hot-adding in function handle_hotplug_event_bridge().

For chips with more than 8 bit ADC resolution, received data was always
masked against 0xfff, ie with a 12 bit mask. This can result in bad data
for chips with 10 bit resolution if those chips have higher bits set
(seen with MAX1139).
The receive buffer was defined as char array. This could result in
unintentional sign extensions if the upper bit in a received byte
was set. Since the chip is configured for unipolar mode, we never
have to handle negative values, and sign extensions are never needed.
