The device IDs of the AMD Cypress/Juniper/Redwood/Cedar/Cayman/Antilles/
Barts/Turks/Caicos HDMI HDA controllers weren't added explicitly
because the generic entry works, but it made the device appearing as
"Generic", and people are confused as if it's no proper HDMI
controller. Add them so that the name shows up properly as "ATI HDMI"
instead of "Generic".
According to Takashi's tests and the lack of complaints, these devices
work fine without disabling snooping.

All async fuse requests must be supplied with extra reference to a fuse
file. This is necessary to ensure that the fuse file is not released until
all in-flight requests are completed. Fuse secondary writeback requests
must obey this rule as well.

BDI_WRITTEN counter is used to estimate bdi bandwidth. It must be
incremented every time as bdi ends page writeback. No matter whether it
was fulfilled by actual write or by discarding the request (e.g. due to
shrunk i_size).
Note that even before writepages patches, the case "Got truncated off
completely" was handled in fuse_send_writepage() by calling
fuse_writepage_finish() which updated BDI_WRITTEN unconditionally.

If writeback happens while fuse is in FUSE_NOWRITE condition, the request
will be queued but not processed immediately (see fuse_flush_writepages()).
Until FUSE_NOWRITE becomes relaxed, more writebacks can happen. They will
be queued as "secondary" requests to that first ("primary") request.
Existing implementation crops only primary request. This is not correct
because a subsequent extending write(2) may increase i_size and then
secondary requests won't be cropped properly. The result would be stale
data written to the server to a file offset where zeros must be.
Similar problem may happen if secondary requests are attached to an
in-flight request that was already cropped.
The patch solves the issue by cropping all secondary requests in
fuse_writepage_end(). Thanks to Miklos for idea.

fuse_writepage_in_flight() returns false if it fails to find request with
given index in fi->writepages. Then the caller proceeds with populating
data->orig_pages[] and incrementing req->num_pages. Hence,
fuse_writepage_in_flight() must revert changes it made in request before
returning false.

When determining the page size we could use to map with the IOMMU, the
page size should also be aligned with the hva, not just the gfn. The
gfn may not reflect the real alignment within the hugetlbfs file.
Most of the time, this works fine. However, if the hugetlbfs file is
backed by non-contiguous huge pages, a multi-huge page memslot starts at
an unaligned offset within the hugetlbfs file, and the gfn is aligned
with respect to the huge page size, kvm_host_page_size() will return the
huge page size and we will use that to map with the IOMMU.
When we later unpin that same memslot, the IOMMU returns the unmap size
as the huge page size, and we happily unpin that many pfns in
monotonically increasing order, not realizing we are spanning
non-contiguous huge pages and partially unpin the wrong huge page.
Ensure the IOMMU mapping page size is aligned with the hva corresponding
to the gfn, which does reflect the alignment within the hugetlbfs file.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
Please accept the following pull request intended for the 3.13 tree...
I had intended to pass most of these to you as much as two weeks ago.
Unfortunately, I failed to account for the effects of bad Internet
connections and my own fatique/laziness while traveling. On the bright
side, at least these have been baking in linux-next for some time!
For the mac80211 bits, Johannes says:
"This time I have two fixes for P2P (which requires not using CCK rates)
and a workaround for APs with broken WMM information."
For the iwlwifi bits, Johannes says:
"I have a few fixes for warnings/issues: one from Alex, fixing scan
timings, one from Emmanuel fixing a WARN_ON in the DVM driver, one from
Stanislaw removing a trigger-happy WARN_ON in the MVM driver and a
change from myself to try to recover when the device isn't processing
commands quickly."
And:
"For this round, I have a lot of changes:
* power management improvements
* BT coexistence improvements/updates
* new device support
* VHT support
* IBSS support (though due to a small bug it requires new firmware)
* various other fixes/improvements."
For the Bluetooth bits, Gustavo says:
"More patches for 3.12, busy times for Bluetooth. More than a 100 commits since
the last pull. The bulk of work comes from Johan and Marcel, they are doing
fixes and improvements all over the Bluetooth subsystem, as the diffstat can
show."
For the ath10k and ath6kl bits, Kalle says:
"Bartosz added support to ath10k for our 10.x AP firmware branch, which
gives us AP specific features and fixes. We still support the main
firmware branch as well just like before, ath10k detects runtime what
firmware is used. Unfortunately the firmware interface in 10.x branch is
somewhat different so there was quite a lot of changes in ath10k for
this.
Michal and Sujith did some performance improvements in ath10k. Vladimir
fixed a compiler warning and Fengguang removed an extra semicolon."
For the NFC bits, Samuel says:
"It's a fairly big one, with the following highlights:
- NFC digital layer implementation: Most NFC chipsets implement the NFC
digital layer in firmware, but others have more basic functionalities
and expect the host to implement the digital layer. This layer sits
below the NFC core.
- Sony's port100 support: This is "soft" NFC USB dongle that expects the
digital layer to be implemented on the host. This is the first user of
our NFC digital stack implementation.
- Secure element API: We now provide a netlink API for enabling,
disabling and discovering NFC attached (embedded or UICC ones) secure
elements. With some userspace help, this allows us to support NFC
payments.
Only the pn544 driver currently supports that API.
- NCI SPI fixes and improvements: In order to support NCI devices over
SPI, we fixed and improved our NCI/SPI implementation. The currently
most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode
and we're planning to use our NCI/SPI framework to implement a
driver for it.
- pn533 fragmentation support in target mode: This was the only missing
feature from our pn533 impementation. We now support fragmentation in
both Tx and Rx modes, in target mode."
On top of all that, brcmfmac and rt2x00 both get the usual flurry
of updates. A few other drivers get hit here or there as well.

All the bits in the VBT child device type have some speciifc meaning,
so looking for an exact match isn't always the right thing. On some
VLVs for example the device type for eDP panels is 0x1806.
If we mask out the bits that could concievably change between different
eDP panels, we are left with the set of bits that should still
tell us if the port is eDP or not.

Add a bitmask to hda_gen_spec indicating NIDs to exclude from the
possible volume controls. That is, when the bit is set, the NID
corresponding to the bit won't be picked as an output volume control
any longer.
Basically this is just a band-aid for working around the issue found
with CS4208 codec, where only the headphone pin has a volume AMP with
different dB steps.

If wChannelconfig is given for some formats but not others, userspace
might not be able to set the channel map.
This is RFC because I'm not sure what the best behaviour is - to guess
the channel map from the given number of channels (it's quite likely
that one channel is MONO and two channels is FL FR), or just to supply
UNKNOWN for all channels.
But the complete lack of channel map for a format leads userspace to
believe that the format is not available at all. Or am I

drm/tegra: Changes for v3.13-rc1
The biggest part of the changes is the decoupling of the host1x and DRM
drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra
from whence it came. There is a lot of cleanup as well, and the drivers
can now be properly unloaded and reloaded.
HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen.
gr2d support was extended to Tegra114 and the gr3d driver that has been
in the works for quite some time finally made it in. All pieces to run
an OpenGL driver on top of an upstream kernel are now available.
Support for syncpoint bases was added by Arto Merilainen. This is useful
for synchronizing between command streams from different engines such as
gr2d and gr3d.
Erik Faye-Lund and Wei Yongjun contributed various small fixes. Thanks!

Commit 2613af0ed18a11d5c566a81f9a6510b73180660a (virtio_net: migrate mergeable
rx buffers to page frag allocators) try to increase the payload/truesize for
MTU-sized traffic. But this will introduce the extra overhead for GSO packets
received because of the frag list. This commit tries to reduce this issue by
coalesce the possible rx frags when possible during rx. Test result shows the
about 15% improvement on full size GSO packet receiving (and even better than
before commit 2613af0ed18a11d5c566a81f9a6510b73180660a).

Sometimes we need to coalesce the rx frags to avoid frag list. One example is

As described in commit 5a581b367 (jiffies: Avoid undefined
behavior from signed overflow), according to the C standard
3.4.3p3, overflow of a signed integer results in undefined
behavior.
To fix this, do as the above commit, and do an unsigned
subtraction, and interpreting the result as a signed
two's-complement number. This is based on the theory from
RFC 1982 and is nicely described in wikipedia here:
https://en.wikipedia.org/wiki/Serial_number_arithmetic#General_Solution
A side-note, I have seen practical issues with the previous logic
when dealing with 16-bit, on a 64-bit machine (gcc version

Slow start now increases cwnd by 1 if an ACK acknowledges some packets,
regardless the number of packets. Consequently slow start performance
is highly dependent on the degree of the stretch ACKs caused by
receiver or network ACK compression mechanisms (e.g., delayed-ACK,
GRO, etc). But slow start algorithm is to send twice the amount of
packets of packets left so it should process a stretch ACK of degree
N as if N ACKs of degree 1, then exits when cwnd exceeds ssthresh. A
follow up patch will use the remainder of the N (if greater than 1)
to adjust cwnd in the congestion avoidance phase.
In addition this patch retires the experimental limited slow start
(LSS) feature. LSS has multiple drawbacks but questionable benefit. The
fractional cwnd increase in LSS requires a loop in slow start even
though it's rarely used. Configuring such an increase step via a global
sysctl on different BDPS seems hard. Finally and most importantly the
slow start overshoot concern is now better covered by the Hybrid slow
start (hystart) enabled by default.

Assinging correct names of the 'hb_mc_edac' and 'hb_l2_edac' edac
modules for module, controller and device. Reported values for
Highbank in dmesg are now:
EDAC MC0: Giving out device to module hb_mc_edac controller
calxeda,hb-ddr-ctrl: DEV fff00000.memory-controller (INTERRUPT)
EDAC DEVICE0: Giving out device to module hb_l2_edac controller
calxeda,hb-sregs-l2-ecc: DEV fff3c200.sregs (INTERRUPT)

Implement edac support for Calxeda ECX-2000.
The ECX-2000 memory controller is similar to Highbank but has
different register bases for error and interrupt registers. There is
an own device tree name "calxeda,ecx-2000-ddr-ctrl" for identification
and initialization of the ECX-2000 and its base addresses.

The DDR controller is slightly different in ECX-2000 and ECX-1000, so we
need to have different nodes for each platform.

This reverts commit 7ebe40f20372688a627ad6c754bc0d1c05df58a9. We forgot
the nfs4_put_delegation call in fs/nfsd/nfs4callback.c which should not
be unhashing the stateid. This lead to warnings from the idr code when
we tried to removed id's twice.

We need to use the _safe version of list_for_each_entry() here otherwise
we have a use after free bug.

Register and enable interrupts after the edac registration. Otherwise
incomming ecc error interrupts lead to crashes during device setup.
Fixing this in drivers for mc and l2.

We already check for nfs_server_capable(inode, NFS_CAP_SECURITY_LABEL)
in nfs4_label_alloc()
We check the minor version in _nfs4_server_capabilities before setting
NFS_CAP_SECURITY_LABEL.

We don't want to be setting capabilities and/or requesting attributes
that are not appropriate for the NFSv4 minor version.
- Ensure that we clear the NFS_CAP_SECURITY_LABEL capability when appropriate
- Ensure that we limit the attribute bitmasks to the mounted_on_fileid
attribute and less for NFSv4.0
- Ensure that we limit the attribute bitmasks to suppattr_exclcreat and
less for NFSv4.1
- Ensure that we limit it to change_sec_label or less for NFSv4.2

Currently, if the server is doing NFSv4.2 and supports labeled NFS, then
our on-the-wire READDIR request ends up asking for the label information,
which is then ignored unless we're doing readdirplus.
This patch ensures that READDIR doesn't ask the server for label information
at all unless the readdir->bitmask contains the FATTR4_WORD2_SECURITY_LABEL
attribute, and the readdir->plus flag is set.
While we're at it, optimise away the 3rd bitmap field if it is zero.

Currently, we fetch the security label when revalidating an inode's
attributes, but don't apply it. This is in contrast to the readdir()
codepath where we do apply label changes.

Jesse Gross says:
====================
Open vSwitch
A set of updates for net-next/3.13. Major changes are:
* Restructure flow handling code to be more logically organized and
easier to read.
* Rehashing of the flow table is moved from a workqueue to flow
installation time. Before, heavy load could block the workqueue for
excessive periods of time.
* Additional debugging information is provided to help diagnose megaflows.
* It's now possible to match on TCP flags.
