Pull new F2FS filesystem from Jaegeuk Kim:
 "Introduce a new file system, Flash-Friendly File System (F2FS), to
  Linux 3.8.

  Highlights:
   - Add initial f2fs source codes
   - Fix an endian conversion bug
   - Fix build failures on random configs
   - Fix the power-off-recovery routine
   - Minor cleanup, coding style, and typos patches"

From the Kconfig help text:

  F2FS is based on Log-structured File System (LFS), which supports
  versatile "flash-friendly" features. The design has been focused on
  addressing the fundamental issues in LFS, which are snowball effect
  of wandering tree and high cleaning overhead.

  Since flash-based storages show different characteristics according to
  the internal geometry or flash memory management schemes aka FTL, F2FS
  and tools support various parameters not only for configuring on-disk
  layout, but also for selecting allocation and cleaning algorithms.

and there's an article by Neil Brown about it on lwn.net:

The atomic64 library uses a handful of static spin locks to implement
atomic 64-bit operations on architectures without support for atomic
64-bit instructions.

Unfortunately, the spinlocks are initialized in a pure initcall and that
is too late for the vfs namespace code which wants to use atomic64
operations before the initcall is run.

This became a problem as of commit 8823c079: "vfs: Add setns support
for the mount namespace".

This leads to BUG messages such as:

  BUG: spinlock bad magic on CPU#0, swapper/0/0
   lock: atomic64_lock+0x240/0x400, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0

    vfs_caches_init+0xe0/0x10c
    start_kernel+0x29c/0x300

coming out early on during boot when spinlock debugging is enabled.

Fix this by initializing the spinlocks statically at compile time.

Pull IOMMU updates from Joerg Roedel:
 "A few new features this merge-window.  The most important one is
  probably, that dma-debug now warns if a dma-handle is not checked with
  dma_mapping_error by the device driver.  This requires minor changes
  to some architectures which make use of dma-debug.  Most of these
  changes have the respective Acks by the Arch-Maintainers.

  Besides that there are updates to the AMD IOMMU driver for refactor
  the IOMMU-Groups support and to make sure it does not trigger a
  hardware erratum.

  The OMAP changes (for which I pulled in a branch from Tony Lindgren's
  tree) have a conflict in linux-next with the arm-soc tree.  The
  conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is
  deleted in the arm-soc tree.  It is safe to delete the file too so
  solve the conflict.  Similar changes are done in the arm-soc tree in
  the common clock framework migration.  A missing hunk from the patch
  in the IOMMU tree will be submitted as a seperate patch when the
  merge-window is closed."

The dma_pte_free_pagetable() function will only free a page table page
if it is asked to free the *entire* 2MiB range that it covers. So if a
page table page was used for one or more small mappings, it's likely to
end up still present in the page tables... but with no valid PTEs.

This was fine when we'd only be repopulating it with 4KiB PTEs anyway
but the same virtual address range can end up being reused for a
*large-page* mapping. And in that case were were trying to insert the
large page into the second-level page table, and getting a complaint
from the sanity check in __domain_mapping() because there was already a
corresponding entry. This was *relatively* harmless; it led to a memory
leak of the old page table page, but no other ill-effects.

Fix it by calling dma_pte_clear_range (hopefully redundant) and
dma_pte_free_pagetable() before setting up the new large page.

On a 4GB RAM machine, where Normal zone is much smaller than DMA32 zone,
the Normal zone gets fragmented in time.  This requires relatively more
pressure in balance_pgdat to get the zone above the required watermark.
Unfortunately, the congestion_wait() call in there slows it down for a
completely wrong reason, expecting that there's a lot of
writeback/swapout, even when there's none (much more common).  After a
few days, when fragmentation progresses, this flawed logic translates to
a very high CPU iowait times, even though there's no I/O congestion at
all.  If THP is enabled, the problem occurs sooner, but I was able to
see it even on !THP kernels, just by giving it a bit more time to occur.

The proper way to deal with this is to not wait, unless there's
congestion.  Thanks to Mel Gorman, we already have the function that
perfectly fits the job.  The patch was tested on a machine which nicely
revealed the problem after only 1 day of uptime, and it's been working
great.

Fix up three empty files in arch/cris/ by sticking placeholder comments in
there to prevent the patch program from deleting them.

I decided not to delete the arch-v*/Kbuild files as it's possibly someone might
want to use them for genhdr-y lines in the future, but they could be deleted
and the pointer lines removed from asm/Kbuild.  The uapi/arch-v*/Kbuild files
ought to be uneffected by such a change.

asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in
uapi/asm/swab.h.  The latter, however, is exported by Kbuild.asm.

We use the FPU and therefore cannot sleep during the crypto
loops.

Things works better when you increment the source buffer pointer

Like the generic versions, we need to support a block size
of '1' for CTR mode AES.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

The basic scheme of the block mode assembler is that we start by
enabling the FPU, loading the key into the floating point registers,
then iterate calling the encrypt/decrypt routine for each block.

For the 256-bit key cases, we run short on registers in the unrolled
loops.

So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that
get clobbered.

The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this.

So if we have a mix of multi-block and single-block calls, the
single-block unrolled 256-bit encrypt/decrypt can run with some
of the key registers clobbered.

Handle this by always explicitly loading those registers before using
the non-unrolled 256-bit macro.

Jussi Kivilinna.

The FPGA can't handled unaligned DMA (yet). So copy into an aligned buffer,
if skb->data isn't suitably aligned.

commit:  cb64edb6 upstream

Above commit may introduce a race between cp_interrupt and dev_close
/ change MTU / dev_open up state. Changes cp_interrupt to tolerate
this.  Change spin_locking in cp_interrupt to avoid possible
but unobserved race.

When building without device tree support (for the mv78x00 SoCs for
example), the build failed because of_irq_count is undeclared. However
mvebu-gpio is not designed to build without device tree support. So
make it depends on OF_CONFIG, remove the #ifdef OF_CONFIG line and the
platform_device_id.

Tested on RD-78x00-mASA, DB-78460-BP, DB-88F6710-BP-DDR3,
DB-MV784MP-GP, Mirabox and OpenBlocks AX3.
