Pull new ARC architecture from Vineet Gupta:
"Initial ARC Linux port with some fixes on top for 3.9-rc1:
I would like to introduce the Linux port to ARC Processors (from
Synopsys) for 3.9-rc1. The patch-set has been discussed on the public
lists since Nov and has received a fair bit of review, specially from
Arnd, tglx, Al and other subsystem maintainers for DeviceTree, kgdb...
The arch bits are in arch/arc, some asm-generic changes (acked by
Arnd), a minor change to PARISC (acked by Helge).
The series is a touch bigger for a new port for 2 main reasons:
1. It enables a basic kernel in first sub-series and adds
ptrace/kgdb/.. later
2. Some of the fallout of review (DeviceTree support, multi-platform-
image support) were added on top of orig series, primarily to
record the revision history.
This updated pull request additionally contains
- fixes due to our GNU tools catching up with the new syscall/ptrace
ABI
- some (minor) cross-arch Kconfig updates."

The kdb_defcmd can only be used to display the available command aliases
while using the kernel debug shell. If you try to define a new macro
while the kernel debugger is active it will oops. The debug shell
macros must use pre-allocated memory set aside at the time kdb_init()
is run, and the kdb_defcmd is restricted to only working at the time
that the kdb_init sequence is being run, which only occurs if you
actually activate the kernel debugger.

Recently some code inspection was done after fixing a problem with
kmalloc used while in the kernel debugger context (which is not
legal), and it turned up the fact that kdb ll command will oops the
kernel.
Given that there have been zero bug reports on the command combined
with the fact it will oops the kernel it is clearly not being used.
Instead of fixing it, it will be removed.

The help command was chopping all the usage instructions such that
they were not readable.
Example:
bta [D|R|S|T|C|Z|E|U|I| Backtrace all processes matching state flag
per_cpu <sym> [<bytes>] [<c Display per_cpu variables
Where as it should look like:
bta [D|R|S|T|C|Z|E|U|I|M|A]
Backtrace all processes matching state flag
per_cpu <sym> [<bytes>] [<cpu>]
Display per_cpu variables
All that is needed is to check the how long the cmd_usage is and jump
to the next line when appropriate.

Maxime reported that strcpy(s->usage, s->usage+1) has no definitive
guarantee that it will work on all archs the same way when you have
overlapping memory. The fix is simple for the kdb code because we
still have the original string memory in the function scope, so we
just have to use that as the argument instead.

Added missing Kconfig option KDB_CONTINUE_CATASTROPHIC which lead to a dead
ifdef block in kernel/debug/kdb/kdb_main.c:73-75.
The code using KDB_CONTINUE_CATASTROPHIC was originally introduced in
commit '5d5314d6795f3c1c0f415348ff8c51f7de042b77' by Jason Wessel.
This patchset ("kdb: core for kgdb back end (1 of 2)")
added platform independent part of kdb to the linux kernel.
The Kernel option however, even though it had the same options and
behaviour on all supported architectures, was part of the x86 and
ia64 patchset of KDB and therefore not pulled into the mainline kernel tree.
I actually took the originally written Kconfig by
Keith Owens <kaos@sgi.com> (2003-06-20 according to KDB changelog)
and changed it to reflect the correct behaviour,
as the KDUMP patchset is not part of the kernel and the expected
functionality is missing from it.

We can't look up the address of the entry point of the function simply
via that function symbol for all architectures.
For PPC64 ABI, actually there is a function descriptors structure.
A function descriptor is a three doubleword data structure that contains
the following values:
* The first doubleword contains the address of the entry point of
the function.
* The second doubleword contains the TOC base address for
the function.
* The third doubleword contains the environment pointer for
languages such as Pascal and PL/1.
So we should call a wapperred dereference_function_descriptor() to get
the address of the entry point of the function.
Note this is also safe for other architecture after refer to
"include/asm-generic/sections.h" since:
dereference_function_descriptor(p) always is (p) if without arched definition.

When locally adding in some additional kdb commands, I stumbled
across an issue with the dynamic expansion of the kdb command table.
When the number of kdb commands exceeds the size of the statically
allocated kdb_base_commands[] array, additional space is allocated in
the kdb_register_repeat() routine.
The unused portion of the newly allocated array was not being initialized
to zero properly and this would result in segfaults when help '?' was
executed or when a search for a non-existing command would traverse the
command table beyond the end of valid command entries and then attempt
to use the non-zeroed area as actual command entries.

"For:
- Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac);
- error injection support for i5100, when EDAC debug is enabled;
- fix edac when it is loaded builtin (early init for the subsystem);
- a "Firmware First" EDAC driver, allowing ghes to report errors via
EDAC (ghes-edac).
With regards to ghes-edac, this fixes a longstanding BZ at Red Hat
that happens with Nehalem and Sandy Bridge CPUs: when both GHES and
i7core_edac or sb_edac are running, the error reports are
unpredictable, as both BIOS and OS race to access the registers. With
ghes-edac, the EDAC core will refuse to register any other concurrent
memory error driver.
This patchset moves the ghes struct definitions to a separate header
file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to
register/unregister and to report errors via ghes-edac. Those changes
were acked by ghes driver maintainer (Huang)."

The new intel_powerclamp thermal cooling device driver was merged in
commit 2af78448ff (Pull thermal management updates from Zhang Rui)
without any data conflicts. But there was a more subtle conflict I
missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77b7
("sched/rt: Move rt specific bits into new header file") had moved that
define from <linux/sched.h> to <linux/sched/rt.h>.
Which caused this build failure:
drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in
And because I don't do a full "make allmodconfig" build after each pull,
I didn't notice until too late. So now the fix is here, separately from
the merge commit.

This series contains changes for the Marvell EBU platforms (mvebu,
orion, kirkwood, dove) that were not part of the first set of pull
requests because of dependencies on the MMC tree, and being submitted
a little late.
Notable changes are:
* More devices get moved out of board files into device tree
descriptions. The remaining devices listed in there have patches
that will get sent for 3.10, after which we can remove a lot of the
board files entirely. We are doing the pinctrl and mmc drivers here,
ethernet and PCI still remain.
* SMP support for mvebu is improved with support for the
local interrupt controller.
* The Guruplug board file gets replaced with a DT description.
Unfortunately, the dependency on the MMC tree turned out to be a much
larger problem than expected, when the MMC maintainer rebased the patches
in his tree that all of the patches in this branch are based on, which
caused merge conflicts between the new and old versions of those patches.
To work around the merge conflicts, this branch rebases all patches
on top of the respective MMC patches that did get merged into 3.9.
The patches are all identical to the versions that were part of
linux-next, but have a new commit date.
Merge conflicts:
* in board-nsa310.c, the gpio.h inclusion was removed prematurely and
put back as a bug fix earlier. With this series it is really not needed
any more.
* The patch to add rtc support was already applied by Andrew Morton,
and conflicts with a second copy that was in this series, which adds
a lot of other devices to arch/arm/boot/dts/armada-370-xp.dtsi.

Merge tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC mvebu platform changes from Olof Johansson:
"This series contains changes for the Marvell EBU platforms (mvebu,
orion, kirkwood, dove) that were not part of the first set of pull
requests because of dependencies on the MMC tree, and being submitted
a little late.
Notable changes are:
- More devices get moved out of board files into device tree
descriptions. The remaining devices listed in there have patches
that will get sent for 3.10, after which we can remove a lot of the
board files entirely. We are doing the pinctrl and mmc drivers
here, ethernet and PCI still remain.
- SMP support for mvebu is improved with support for the local
interrupt controller.
- The Guruplug board file gets replaced with a DT description.
Unfortunately, the dependency on the MMC tree turned out to be a much
larger problem than expected, when the MMC maintainer rebased the
patches in his tree that all of the patches in this branch are based
on, which caused merge conflicts between the new and old versions of
those patches.
To work around the merge conflicts, this branch rebases all patches on
top of the respective MMC patches that did get merged into 3.9. The
patches are all identical to the versions that were part of
linux-next, but have a new commit date."

This branch contains of devicetree changes for the Freescale i.MX platform.
The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process since
every line of the file is touched.
On top of that are a handful of the regular changes; enabling more boards
as DT-based instead of legacy board files (mx25pdk), enabling another
driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other platforms
in the future.

Pull nfsd changes from J Bruce Fields:
"Miscellaneous bugfixes, plus:
- An overhaul of the DRC cache by Jeff Layton. The main effect is
just to make it larger. This decreases the chances of intermittent
errors especially in the UDP case. But we'll need to watch for any
reports of performance regressions.
- Containerized nfsd: with some limitations, we now support
per-container nfs-service, thanks to extensive work from Stanislav
Kinsbursky over the last year."
Some notes about conflicts, since there were *two* non-data semantic
conflicts here:
- idr_remove_all() had been added by a memory leak fix, but has since
become deprecated since idr_destroy() does it for us now.
- xs_local_connect() had been added by this branch to make AF_LOCAL
connections be synchronous, but in the meantime Trond had changed the
calling convention in order to avoid a RCU dereference.
There were a couple of more obvious actual source-level conflicts due to
the hlist traversal changes and one just due to code changes next to
each other, but those were trivial.

improved hashing strategy across storage nodes (when the server side
supports it too).

operations. Several patches from Yan, Zheng fix various mds/client
issues that turned up during multi-mds torture tests.
