From Dinh Nguyen, this is a series of patches introducing support for
socfpga hardware (Altera Cyclone5). It also includes a cleanup that
moves some of the ARMv7 cache maintenance functions to a common location,
since three other platforms aready implemented it separately.
* socfpga/hw:
arm: socfpga: Add SMP support for actual socfpga harware
arm: Add v7_invalidate_l1 to cache-v7.S
arm: socfpga: Add entries to enable make dtbs socfpga
arm: socfpga: Add new device tree source for actual socfpga HW
Trivial conflict in arch/arm/mach-tegra/headsmp.S.

Because the CPU1 start address is different for socfpga-vt and
socfpga-cyclone5, we add code to use the correct CPU1 start addr.

From Stephen Warren:
ARM: tegra: USB driver cleanup
The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-soc-ccf.

From Stephen Warren:
ARM: tegra: Common Clock Framework rework
Tegra already supports the common clock framework, but had issues:
1) The clock driver was located in arch/arm/mach-tegra/ rather than
drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.

The Tegra20 CAR (Clock And Reset) Controller controls most aspects of
most clocks within Tegra20. The device tree binding models this as a
single monolithic clock provider, which exports many clocks. This reduces
the number of nodes needed in device tree to represent these clocks.
This binding is only useful for Tegra20; the set of clocks that exists on
Tegra30 is sufficiently different to merit its own binding.

Define the 2.12 bzImage boot protocol: add xloadflags and additional
fields to allow the command line, initramfs and struct boot_params to
live above the 4 GiB mark.
The xloadflags now communicates if this is a 64-bit kernel with the
legacy 64-bit entry point and which of the EFI handover entry points
are supported.
Avoid adding new read flags to loadflags because of claimed
bootloaders testing the whole byte for == 1 to determine bzImageness
at least until the issue can be researched further.
This is based on patches by Yinghai Lu and David Woodhouse.

Before attempting to activate a RAID array, it is checked for sufficient
redundancy. That is, we make sure that there are not too many failed
devices - or devices specified for rebuild - to undermine our ability to
activate the array. The current code performs this check twice - once to
ensure there were not too many devices specified for rebuild by the user
('validate_rebuild_devices') and again after possibly experiencing a failure
to read the superblock ('analyse_superblocks'). Neither of these checks are
sufficient. The first check is done properly but with insufficient
information about the possible failure state of the devices to make a good
determination if the array can be activated. The second check is simply
done wrong in the case of RAID10 because it doesn't account for the
independence of the stripes (i.e. mirror sets). The solution is to use the
properly written check ('validate_rebuild_devices'), but perform the check
after the superblocks have been read and we know which devices have failed.
This gives us one check instead of two and performs it in a location where
it can be done right.
Only RAID10 was affected and it was affected in the following ways:
- the code did not properly catch the condition where a user specified
a device for rebuild that already had a failed device in the same mirror
set. (This condition would, however, be caught at a deeper level in MD.)
- the code triggers a false positive and denies activation when devices in
independent mirror sets have failed - counting the failures as though they
were all in the same set.
The most likely place this error was introduced (or this patch should have
been included) is in commit 4ec1e369 - first introduced in v3.7-rc1.
Consequently this fix should also go in v3.7.y, however there is a
small conflict on the .version in raid_target, so I'll submit a
separate patch to -stable.

Currently, the PM core disables runtime PM for all devices right
after executing subsystem/driver .suspend() callbacks for them
and re-enables it right before executing subsystem/driver .resume()
callbacks for them. This may lead to problems when there are
two devices such that the .suspend() callback executed for one of
them depends on runtime PM working for the other. In that case,
if runtime PM has already been disabled for the second device,
the first one's .suspend() won't work correctly (and analogously
for resume).
To make those issues go away, make the PM core disable runtime PM
for devices right before executing subsystem/driver .suspend_late()
callbacks for them and enable runtime PM for them right after
executing subsystem/driver .resume_early() callbacks for them. This
way the potential conflitcs between .suspend_late()/.resume_early()
and their runtime PM counterparts are still prevented from happening,
but the subtle ordering issues related to disabling/enabling runtime
PM for devices during system suspend/resume are much easier to avoid.

Add 3 new variables and sysctls to tune them (by one "next_id" variable
for messages, semaphores and shared memory respectively). This variable
can be used to set desired id for next allocated IPC object. By default
it's equal to -1 and old behaviour is preserved. If this variable is
non-negative, then desired idr will be extracted from it and used as a
start value to search for free IDR slot.
Notes:
1) this patch doesn't guarantee that the new object will have desired
id. So it's up to user space how to handle new object with wrong id.
2) After a sucessful id allocation attempt, "next_id" will be set back
to -1 (if it was non-negative).

Pull driver core __dev* removal patches - take 3 - from Greg Kroah-Hartman:
"Here are the remaining __dev* removal patches against the 3.8-rc2
tree. All of these patches were previously sent to the subsystem
maintainers, most of them were picked up and pushed to you, but there
were a number that fell through the cracks, and new drivers were added
during the merge window, so this series cleans up the rest of the
instances of these markings.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from the kernel documentation.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Pull nfsd update from Bruce Fields:
"Included this time:
- more nfsd containerization work from Stanislav Kinsbursky: we're
not quite there yet, but should be by 3.9.
- NFSv4.1 progress: implementation of basic backchannel security
negotiation and the mandatory BACKCHANNEL_CTL operation. See
http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues
for remaining TODO's
- Fixes for some bugs that could be triggered by unusual compounds.
Our xdr code wasn't designed with v4 compounds in mind, and it
shows. A more thorough rewrite is still a todo.
- If you've ever seen "RPC: multiple fragments per record not
supported" logged while using some sort of odd userland NFS client,
that should now be fixed.
- Further work from Jeff Layton on our mechanism for storing
information about NFSv4 clients across reboots.
- Further work from Bryan Schumaker on his fault-injection mechanism
(which allows us to discard selective NFSv4 state, to excercise
rarely-taken recovery code paths in the client.)
- The usual mix of miscellaneous bugs and cleanup.
Thanks to everyone who tested or contributed this cycle."
