Commit 4c94c8b5 "ARM: tegra: update device trees for USB binding rework"
added regulator definitions for GPIO-controlled USB VBUS. However, none
of these contained the essential DT property enable-active-high. Add
this so that the regulator definitions are correct.

Renesas ARM based SoC fixes for v3.11

* Correct GIO3 base addresses for EMEV2 SoC
  - This bug bug added when GPIO support was added for the EMEV2 SoC
    in v3.5

* Correct SCIFB0 resources for r8a77a4 SoC
  - This was a bug was added when SCIF support was added for the r8a77a4 SoC
    in v3.10

  ARM: shmobile: emev2 GIO3 resource fix
  ARM: shmobile: r8a73a4: Fix resources for SCIFB0

This updates multi_v7_defconfig to boot on at least Tegra2 Seaboard and
Panda ES. I lack working hardware for most of the platforms that were
enabled to compare with, so I could only verify those two for now. Still,
I enabled all of the available ones for build coverage purposes.

Beyond base platforms, things like PRINTK_TIME, filesystems, MMC, USB,
INET and UNIX networking was enabled. I'm sure we'll keep adding more
over time, but this gets us off the ground for semi-regular boot testing.

Pull ARM SoC late changes from Arnd Bergmann:
 "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"

Pull ARM SoC driver specific changes from Arnd Bergmann:
 "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."

Pull ARM SoC device tree changes from Arnd Bergmann:
 "These changes from 30 individual branches for the most part update
  device tree files, but there are also a few source code changes that
  have crept in this time, usually in order to atomically move over a
  driver from using hardcoded data to DT probing.

  A number of platforms change their DT files to use the C preprocessor,
  which is causing a bit of churn, but that is hopefully only this once"

Pull ARM SoC board specific changes from Arnd Bergmann:
 "These are 18 branches on 9 platforms with board specific changes,
  mostly for defconfig files, but nothing really exciting in here.

  Since the shmobile platform still uses board files for some of the
  newer machines, we get a few changes there as the result of drivers
  getting enabled for those boards.  This causes some conflicts with
  contents getting added from multiple branches in sh-mobile specific
  files.  Renesas is putting a lot of work into migrating to device-tree
  based setup, which will make all those files obsolete in the future
  and avoid both the conflicts and the need to have these files in the
  first place."

Pull ARM SoC specific changes from Arnd Bergmann:
 "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."

Pull ARM SoC cleanups from Arnd Bergmann:
 "This contains cleanups as preparation for other branches adding new
  features, we pulled 16 branches for 9 platforms into this one.

  Most notable here is the removal of support for ATAGS based OMAP4
  systems.  Since all OMAP4 machines are fully functional with DT based
  booting in 3.10, we can remove a lot of code here.

  Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
  which means we need no machine descriptors in a lot more cases and can
  boot additional machines by just having the respective device drivers
  enabled."

Pull ext4 update from Ted Ts'o:
 "Lots of bug fixes, cleanups and optimizations.  In the bug fixes
  category, of note is a fix for on-line resizing file systems where the
  block size is smaller than the page size (i.e., file systems 1k blocks
  on x86, or more interestingly file systems with 4k blocks on Power or
  ia64 systems.)

  In the cleanup category, the ext4's punch hole implementation was
  significantly improved by Lukas Czerner, and now supports bigalloc
  file systems.  In addition, Jan Kara significantly cleaned up the
  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.

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 user requests many data writes and fsync together, the last updated i_size
should be stored to the inode block consistently.

But, previous write_end just marks the inode as dirty and doesn't update its
metadata into its inode block.
After that, fsync just writes the inode block with newly updated data index
excluding inode metadata updates.

So, this patch introduces write_end in which updates inode block too when the
i_size is changed.

This patch removes check_prefree_segments initially designed to enhance the
performance by narrowing the range of LBA usage across the whole block device.

When allocating a new segment, previous f2fs tries to find proper prefree
segments, and then, if finds a segment, it reuses the segment for further
data or node block allocation.

However, I found that this was totally wrong approach since the prefree segments
have several data or node blocks that will be used by the roll-forward mechanism
operated after sudden-power-off.

Let's assume the following scenario.

/* write 8MB with fsync */
for (i = 0; i < 2048; i++) {
	offset = i * 4096;
	write(fd, offset, 4KB);
	fsync(fd);
}

In this case, naive segment allocation sequence will be like:
 data segment: x, x+1, x+2, x+3
 node segment: y, y+1, y+2, y+3.

But, if we can reuse prefree segments, the sequence can be like:
 data segment: x, x+1, y, y+1
 node segment: y, y+1, y+2, y+3.
Because, y, y+1, and y+2 became prefree segments one by one, and those are
reused by data allocation.

After conducting this workload, we should consider how to recover the latest
inode with its data.
If we reuse the prefree segments such as y or y+1, we lost the old node blocks
so that f2fs even cannot start roll-forward recovery.

Therefore, I suggest that we should remove reusing prefree segments.

Optimize the while loop condition

Since this condition will always be true and while loop will
be terminated by the following condition in code:

if (segno >= TOTAL_SEGS(sbi))
    break;
Hence we can replace the while loop condition with while(1)
instead of always checking for segno to be less than Total segs.

Also we do not need to use TOTAL_SEGS() everytime. We can store
this value in a local variable since this value is constant.

Both hole punch and truncate use ext4_ext_rm_leaf() for removing
blocks.  Currently we choose the last extent as the starting
point for removing blocks:

	ex = EXT_LAST_EXTENT(eh);

This is OK for truncate but for hole punch we can optimize the extent
selection as the path is already initialized.  We could use this
information to select proper starting extent.  The code change in this
patch will not affect truncate as for truncate path[depth].p_ext will
always be NULL.

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.

The function mpage_released_unused_page() must only be called once;
otherwise the kernel will BUG() when the second call to
mpage_released_unused_page() tries to unlock the pages which had been
unlocked by the first call.

Also restructure the error handling so that we only give up on writing
the dirty pages in the case of ENOSPC where retrying the allocation
won't help.  Otherwise, a transient failure, such as a kmalloc()
failure in calling ext4_map_blocks() might cause us to give up on
those pages, leading to a scary message in /var/log/messages plus data
loss.

Once we decrement transaction->t_updates, if this is the last handle
holding the transaction from closing, and once we release the
t_handle_lock spinlock, it's possible for the transaction to commit
and be released.  In practice with normal kernels, this probably won't
happen, since the commit happens in a separate kernel thread and it's
unlikely this could all happen within the space of a few CPU cycles.

On the other hand, with a real-time kernel, this could potentially
happen, so save the tid found in transaction->t_tid before we release
t_handle_lock.  It would require an insane configuration, such as one
where the jbd2 thread was set to a very high real-time priority,
perhaps because a high priority real-time thread is trying to read or
write to a file system.  But some people who use real-time kernels
have been known to do insane things, including controlling
laser-wielding industrial robots.  :-)
