These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,
the list should be kept in alphabetical order when
resolving.

These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

These changes are all to SoC-specific code, a total of 33 branches on
17 platforms were pulled into this. Like last time, Renesas sh-mobile
is now the platform with the most changes, followed by OMAP and EXYNOS.
Two new platforms, TI Keystone and Rockchips RK3xxx are added in
this branch, both containing almost no platform specific code at all,
since they are using generic subsystem interfaces for clocks, pinctrl,
interrupts etc. The device drivers are getting merged through the
respective subsystem maintainer trees.
One more SoC (u300) is now multiplatform capable and several others
(shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
towards that goal with this series but need more work.
Also noteworthy is the work on PCI here, which is traditionally part of
the SoC specific code. With the changes done by Thomas Petazzoni, we can
now more easily have PCI host controller drivers as loadable modules and
keep them separate from the platform code in drivers/pci/host. This has
already led to the discovery that three platforms (exynos, spear and imx)
are actually using an identical PCIe host controller and will be able
to share a driver once support for spear and imx is added.
Conflicts:
* asm/glue-proc.h has one CPU type getting added that conflicts
with another addition in 3.10-rc7
* Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

booting in 3.10, we can remove a lot of code here.
Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,

Here's the large staging tree merge for 3.11-rc1
Huge thing here is the Lustre client code. Unfortunatly, due to it not
building properly on a wide variety of different architectures (this was
production code???), it is currently disabled from the build so as to
not annoy people.
Other than Lustre, there are loads of comedi patches, working to clean
up that subsystem, iio updates and new drivers, and a load of cleanups
from the OPW applicants in their quest to get a summer internship.
All of these have been in the linux-next releases for a while (hence the
Lustre code being disabled.)

write submission code path. We also improved error checking and added
a few sanity checks.
In the optimizations category, two major optimizations deserve
mention. The first is that ext4_writepages() is now used for
nodelalloc and ext3 compatibility mode. This allows writes to be
submitted much more efficiently as a single bio request, instead of
being sent as individual 4k writes into the block layer (which then
relied on the elevator code to coalesce the requests in the block
queue). Secondly, the extent cache shrink mechanism, which was
introduce in 3.9, no longer has a scalability bottleneck caused by the
i_es_lru spinlock. Other optimizations include some changes to reduce
CPU usage and to avoid issuing empty commits unnecessarily.

When sync does it's WB_SYNC_ALL writeback, it issues data Io and
then immediately waits for IO completion. This is done in the
context of the flusher thread, and hence completely ties up the
flusher thread for the backing device until all the dirty inodes
have been synced. On filesystems that are dirtying inodes constantly
and quickly, this means the flusher thread can be tied up for
minutes per sync call and hence badly affect system level write IO
performance as the page cache cannot be cleaned quickly.
We already have a wait loop for IO completion for sync(2), so cut
this out of the flusher thread and delegate it to wait_sb_inodes().
Hence we can do rapid IO submission, and then wait for it all to
complete.
Effect of sync on fsmark before the patch:

And a single sync pass took:
real 0m52.407s
user 0m0.000s
sys 0m0.090s
After the patch, there is no impact on fsmark results, and each
individual sync(2) operation run concurrently with the same fsmark
workload takes roughly 7s:
real 0m6.930s
user 0m0.000s
sys 0m0.039s
IOWs, sync is 7-8x faster on a busy filesystem and does not have an
adverse impact on ongoing async data write operations.

If jbd2_journal_restart() fails the handle will have been disconnected
from the current transaction. In this situation, the handle must not
be used for for any jbd2 function other than jbd2_journal_stop().
Enforce this with by treating a handle which has a NULL transaction
pointer as an aborted handle, and issue a kernel warning if
jbd2_journal_extent(), jbd2_journal_get_write_access(),
jbd2_journal_dirty_metadata(), etc. is called with an invalid handle.
This commit also fixes a bug where jbd2_journal_stop() would trip over
a kernel jbd2 assertion check when trying to free an invalid handle.
Also move the responsibility of setting current->journal_info to
start_this_handle(), simplifying the three users of this function.

New method - ->iterate(file, ctx). That's the replacement for ->readdir();
it takes callback from ctx->actor, uses ctx->pos instead of file->f_pos and
calls dir_emit(ctx, ...) instead of filldir(data, ...). It does *not*
update file->f_pos (or look at it, for that matter); iterate_dir() does the
update.
Note that dir_emit() takes the offset from ctx->pos (and eventually
filldir_t will lose that argument).

iterate_dir(): new helper, replacing vfs_readdir().
struct dir_context: contains the readdir callback (and will get more stuff
in it), embedded into whatever data that callback wants to deal with;
eventually, we'll be passing it to ->readdir() replacement instead of
(data,filldir) pair.

Pull networking fixes from David Miller:
1) Found via trinity:
If you connect up an ipv6 socket to an ipv4 mapped address then an
ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the
route cached in the socket is an ipv6 one. In this case there is an
ipv4 route attached, so it gets stomped on.
Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric
Dumazet.
2) AF_KEY notifications leak some kernel memory to userspace, fix from
Mathias Krause.
3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del
doesn't validate that the device being deleted is actually a DLCI
one. Fixes from Li Zefan.
4) Length check on bluetooth l2cap information responses is wrong, each
response type has a different lenth, so we should make sure it's in
a given range rather than enforce one single valid length. From
Jaganath Kanakkassery.
5) Receive FIFO overflow is really easy to trigger in stress scenerios
in the sh_eth driver, but the event isn't being handled properly at
all. Specifically, the mask of error interrupts doesn't include the
event so we never clear it, resulting in the driver becomming wedged
processing an interrupt that never gets cleared.
Fix from Sergei Shtylyov.
6) qlcnic sleeps while holding a spinlock, use mdelay() instead of
msleep(). From Shahed Shaikh.
7) Missing curly braces causes SIP netfilter NAT module to always drop
packets. Fix from Balazs Peter Odor.
8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing
the timer to dereference crap when it fires. Fix from Gao Feng.
9) Missing RCU protection around txq->axq_acq traversal in
ath_txq_schedule(). Fix from Felix Fietkau.
10) Idle state transition test in ath9k_htc_config() is reversed, fix
from Sujith Manoharan.
11) IPV6 forwarding handles unicast Router Alert packets incorrectly.
It tests the wrong option state. Previously opt->ra being non-zero
indicated a router alert marking in the SKB, but now it's indicated
by a bit in opt->flags. Fix from YOSHIFUJI Hideaki.
12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet.
13) get_user_pages_fast() error handling in TUN and MACVTAP use the same
local variable for the base index and the loop iterator for page
traversal, oops! Fix from Michael S Tsirkin.
14) ipv6_get_lladdr() can fail, and we must therefore check it's return
value in inet6_set_iftoken(). For from Hannes Frederic Sowa.
15) If you change an interface name and meanwhile can sneak in something
that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can
deadlock with CONFIG_PREEMPT=n. Fix this by providing a helper
function that properly uses raw_seqcount_begin(). From Nicolas
Schichan.
16) Chain noise calibration test is inverted in iwlwifi, fix from
Nikolay Martynov.
17) Properly set TX iwlwifi descriptor flags for back requests. Fix
from Emmanuel Grumbach.
18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP
module, fix from Pablo Neira Ayuso.
19) Some crummy APs don't provide the proper High Throughput info in
association response frames. Add a workaround by assume we'll use
whatever is in the beacon/probe. Fix from Johannes Berg.
20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and
channel width). Fix from Simon Wunderlich.
21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented
frames. Fix from Phil Oester.
22) Fix rate control regression causing iwlwifi/iwlegacy chips to use
1Mbit/s on pre-11n networks. From Moshe Benji and Stanslaw Gruszka.
23) Disable brcmsmac power-save functions, they cause regressions. From
Arend van Spriel.
24) Enforce a sane minimum MTU in l2cap_build_cmd() otherwise we can
easily crash. Fix from Anderson Lizardo.
25) If a learning packet arrives during vxlan_stop() we crash, easily
fixed by checking netif_running(). From Stephen Hemminger.
26) Static vxlan FDB entries should not be migrated, also from Stephen.
27) skb_clone() failures not handled in vxlan_xmit(), oops. Also from
Stephen.
28) Add minimal driver for AR816x/AR817x ethernet chips, from Johannes
Berg.
29) Fix regression in userspace VLAN acceleration control, added by the
802.1ad support changes. Fix from Fernando Luis Vazquez Cao.
30) Interval selection for MLD queries in the bridging code was
reversed. Fix from Linus Lüssing.
31) ipv6's ndisc_send_redirect() erroneously writes to the packet we
received not the packet we are building to send out. Fix from
Matthias Schiffer.
32) Don't free netdev before unregistering it, in usb_8dev can driver.

36) phy_type attribute created by SFC driver should not be writable.

When the kernel (compiled with CONFIG_PREEMPT=n) is performing the
rename of a network interface, it can end up waiting for a workqueue
to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a
SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to
the fact that read_secklock_begin() will spin forever waiting for the
writer process (the one doing the interface rename) to update the
devnet_rename_seq sequence.
This patch fixes the problem by adding a helper (netdev_get_name())
and using it in the code handling the SIOCGIFNAME ioctl and
SO_BINDTODEVICE setsockopt.
The netdev_get_name() helper uses raw_seqcount_begin() to avoid
spinning forever, waiting for devnet_rename_seq->sequence to become
even. cond_resched() is used in the contended case, before retrying
the access to give the writer process a chance to finish.
The use of raw_seqcount_begin() will incur some unneeded work in the
reader process in the contended case, but this is better than
deadlocking the system.

The futex_keys of process shared futexes are generated from the page
offset, the mapping host and the mapping index of the futex user space
address. This should result in an unique identifier for each futex.
Though this is not true when futexes are located in different subpages
of an hugepage. The reason is, that the mapping index for all those
futexes evaluates to the index of the base page of the hugetlbfs
mapping. So a futex at offset 0 of the hugepage mapping and another
one at offset PAGE_SIZE of the same hugepage mapping have identical
futex_keys. This happens because the futex code blindly uses
page->index.
Steps to reproduce the bug:
1. Map a file from hugetlbfs. Initialize pthread_mutex1 at offset 0
and pthread_mutex2 at offset PAGE_SIZE of the hugetlbfs
mapping.
The mutexes must be initialized as PTHREAD_PROCESS_SHARED because
PTHREAD_PROCESS_PRIVATE mutexes are not affected by this issue as
their keys solely depend on the user space address.
2. Lock mutex1 and mutex2
3. Create thread1 and in the thread function lock mutex1, which
results in thread1 blocking on the locked mutex1.
4. Create thread2 and in the thread function lock mutex2, which
results in thread2 blocking on the locked mutex2.
5. Unlock mutex2. Despite the fact that mutex2 got unlocked, thread2
still blocks on mutex2 because the futex_key points to mutex1.
To solve this issue we need to take the normal page index of the page
which contains the futex into account, if the futex is in an hugetlbfs
mapping. In other words, we calculate the normal page mapping index of
the subpage in the hugetlbfs mapping.
Mappings which are not based on hugetlbfs are not affected and still
use page->index.
Thanks to Mel Gorman who provided a patch for adding proper evaluation
functions to the hugetlbfs code to avoid exposing hugetlbfs specific
details to the futex code.

* it needlessly attracts mail filters
This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending
on the situation. Modules with ci13xxx prefix are also renamed accordingly
and aliases are added for compatibility. Otherwise, no functional changes.

Merge tag 'omap-for-v3.11/mailbox-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
From Tony Lindgren:
Move OMAP Mailbox framework to drivers via Suman Anna <s-anna@ti.com>
The OMAP Mailbox driver framework is moved out of arch/arm folder
into drivers/mailbox folder, to re-enable building it and also serve
as a baseline for adapting to the new mailbox driver framework. The
changes mainly contain:
- a minor bug fix and cleanup of mach-specific mailbox code
- remove any header dependencies from plat-omap for multi-platform
support
- represent mailbox device data through platform data/hwmod attrs
- move the omap mailbox code out of plat-omap/mach-omapX to
drivers/mailbox folder
* tag 'omap-for-v3.11/mailbox-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
mailbox/omap: move the OMAP mailbox framework to drivers
ARM: OMAP2+: add user and fifo info to mailbox platform data
ARM: OMAP2+: mbox: remove dependencies with soc.h
omap: mailbox: correct the argument type for irq ops
omap: mailbox: call request_irq after mbox queues are allocated
omap: mailbox: check iomem resource before dereferencing it

This pull request moves DaVinci EDMA library to
arch/arm/common so it can be used by OMAP based AM335x.
This is a temporary step until all drivers are converted
to use the dmaengine driver in drivers/dma/edma.c.
Several drivers like SPI, MMC/SD have already been converted.
Some like audio are pending.
The other two patches in the pull request are cleanup in nature.

The use of the 'readl' and 'writel' identifiers here causes build errors on
architectures where those are macros. This renames the fields to read32/write32
to avoid the problem.
