The changes to export dirty_writeback_interval are from Artem's s_dirt
cleanup patch series. The same is true of the change to remove the
s_dirt helper functions which never got used by anyone in-tree. I've
run these changes by Al Viro, and am carrying them so that Artem can
more easily fix up the rest of the file systems during the next merge
window. (Originally we had hopped to remove the use of s_dirt from
ext4 during this merge window, but his patches had some bugs, so I
ultimately ended dropping them from the ext4 tree.)

In d_materialise_unique() there are 3 subcases to the 'aliased dentry'
case; in two subcases the inode i_lock is properly released but this
does not occur in the -ELOOP subcase.
This seems to have been introduced by commit 1836750115 ("fix loop
checks in d_materialise_unique()").

[ Added a comment, and moved the unlock to where we generate the -ELOOP,
which seems to be more natural.
You probably can't actually trigger this without a buggy network file
server - d_materialize_unique() is for finding aliases on non-local
filesystems, and the d_ancestor() case is for a hardlinked directory
loop.
But we should be robust in the case of such buggy servers anyway. ]

fixes-non-critical has already been merged upstream, and there are a
handful of annoying context conflicts that it makes sense to resolve

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current

970 and Power4 don't support "continuous sampling" which means that
when we aren't in marked instruction sampling mode (marked events),
SIAR isn't updated with the last instruction sampled before the
perf interrupt. On those processors, we must thus use the exception
SRR0 value as the sampled instruction pointer.
Those processors also don't support the SIPR and SIHV bits in MMCRA
which means we need some kind of heuristic to decide if SIAR values
represent kernel or user addresses.

Ambient temperature too high reported by firmware.

FDT nodes whose names have prefix "pci" are regarded as PHBs.
That's inappropriate because some PCI bridges possibilly have
names leading with "pci". It caused EEH is enabled on same
PCI devices for towice.
The patch fixes the above issue. Besides, the PHBs are expected
to be figured out from FDT before enable EEH on them. Therefore,
it's resonable to retrieve the PHBs from the global linked list
traced by variable "hose_list" insteading poking them from FDT.
For the EEH implementation on pSeries platform, RTAS is critical
because all low-level functions are implemented based on RTAS.
Therefore, we should make sure "/rtas" OF node is available and
ready before to enable EEH core. However, it actually introduced
duplicate since the previous pSeries platform dependent initialization
function already do the check. Besides, we want to make eeh core
platform independent, so RTAS related staff should be removed there.
The patch removes the duplicate check on "/rtas" OF node for eeh
core.

The patch removes the eeh information from pci_dn since the eeh
device (struct eeh_dev) already contained those information and
the copy in pci_dn is no longer used except for the pseries iommu
mapping code, which we change to retrieve the PE address from eeh
device instead.

Originally, the PCI sensitive OF node is tracing the eeh device
through struct device_node->edev. However, it was regarded as
bad idea.
The patch removes struct device_node->edev and uses PCI_DN to
trace the corresponding eeh device according to BenH's comments.

Pull networking fixes from David Miller:
1) Name string overrun fix in gianfar driver from Joe Perches.
2) VHOST bug fixes from Michael S. Tsirkin and Nadav Har'El
3) Fix dependencies on xt_LOG netfilter module, from Pablo Neira Ayuso.
4) Fix RCU locking in xt_CT, also from Pablo Neira Ayuso.
5) Add a parameter to skb_add_rx_frag() so we can fix the truesize
adjustments in the drivers that use it. The individual drivers
aren't fixed by this commit, but will be dealt with using follow-on
commits. From Eric Dumazet.
6) Add some device IDs to qmi_wwan driver, from Andrew Bird.
7) Fix a potential rcu_read_lock() imbalancein rt6_fill_node(). From

Most of these patches convert code from using static platform data to
describing the hardware in the device tree. This is only the first
half of the changes for v3.4 because a lot of patches for this topic
came in the last week before the merge window.

These are all specific to some driver. They are typically the platform
side of a change in the drivers directory, such as adding a new driver
or extending the interface to the platform. In cases where there is no
maintainer for the driver, or the maintainer prefers to have the
platform changes in the same branch as the driver changes, the patches
to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.
The new export of tegra_chip_uid conflicts with other changes in fuse.c.
In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
