      ARM: dt: tegra: harmony: add regulators · 3cc404de
      Laxman Dewangan authored 
      Harmony uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.

Based on Ventana regulator patch by Stephen Warren <swarren@nvidia.com>
and converted to Harmony.

swarren made the following changes:
* Added ldo0 regulator configuration to device tree, and updated
  board-harmony-pcie.c for the new regulator name.
* Fixed vdd_1v05's voltage from 10.5V to 1.05V.
* Modified board-harmony-pcie.c to obtain the en_vdd_1v05 GPIO number at
  run-time from device tree instead of hard-coding it.
* Removed board-harmony{-power.c,.h} now that they're unused.
* Disabled vdd_1v05 regulator; the code in board-harmony-pcie.c hijacks
  this GPIO for now. This will be fixed when the PCIe driver is re-
  written as a driver. The code can't regulator_get("vdd_1v05") right
  now, because the vdd_1v05 regulator's probe gets deferred due to its
  supply being the PMIC, which gets probed after the regulator the first
  time around, and this dependency is only resolved by repeated probing,
  which happens when deferred_probe_initcall() is called, which happens
  in a late initcall, whose runtime order relative to harmony_pcie_init()
  is undefined, since that's also called from a late initcall.
* Removed unused harmony_pcie_initcall().

      ARM: tegra: remove board (but not DT) support for Harmony · bb25af81
      Stephen Warren authored 
      Harmony can be booted using device tree with equal functionality as when
booted using a board file. Remove as much of the board file as is
possible, since it's no longer needed.

Two special-cases are still left in board-dt-tegra20.c, since the Tegra
PCIe driver doesn't support device tree yet, and the Harmony .dts file
doesn't yet describe regulators which are needed for PCIe. This logic is
now enabled unconditionally rather than via CONFIG_MACH_HARMONY. While
this is more code than other boards, it's still unlikely to be much of a
problem, and both regulators and PCIe should be supported via device tree
in the near future, allowing the remaining code to be removed.

      ARM: tegra: remove board (but not DT) support for Paz00 · cff1dfbf
      Stephen Warren authored 
      Paz00 (Toshiba AC100) can be booted using device tree with equal
functionality as when booted using a board file. Remove as much of the
board file as is possible, since it's no longer needed.

One special-case is still left in board-dt-tegra20.c, since there is no
way to create a WiFi rfkill device from device tree yet. This logic is
now enabled unconditionally rather than via CONFIG_MACH_PAZ00. The extra
cases where it's enabled (.configs which did not enable Paz00 support)
shouldn't impact much since the amount of code is tiny.

      Btrfs: fix that repair code is spuriously executed for transid failures · 256dd1bb
      Stefan Behrens authored 
      If verify_parent_transid() fails for all mirrors, the current code
calls repair_io_failure() anyway which means:
- that the disk block is rewritten without repairing anything and
- that a kernel log message is printed which misleadingly claims
  that a read error was corrected.

This is an example:
parent transid verify failed on 615015833600 wanted 110423 found 110424
parent transid verify failed on 615015833600 wanted 110423 found 110424
btrfs read error corrected: ino 1 off 615015833600 (dev /dev/...)

It is wrong to ignore the results from verify_parent_transid() and to
call repair_eb_io_failure() when the verification of the transids failed.
This commit fixes the issue.

      Btrfs: fix a dio write regression · 24c03fa5
      Liu Bo authored 
      This bug is introduced by commit 3b8bde746f6f9bd36a9f05f5f3b6e334318176a9
(Btrfs: lock extents as we map them in DIO).

In dio write, we should unlock the section which we didn't do IO on in case that
we fall back to buffered write.  But we need to not only unlock the section
but also cleanup reserved space for the section.

This bug was found while running xfstests 133, with this 133 no longer complains.

      Btrfs: fix deadlock with freeze and sync V2 · bd7de2c9
      Josef Bacik authored 
      We can deadlock with freeze right now because we unconditionally start a
transaction in our ->sync_fs() call.  To fix this just check and see if we
have a running transaction to commit.  This saves us from the deadlock
because at this point we'll have the umount sem for the sb so we're safe
from freezes coming in after we've done our check.  With this patch the
freeze xfstests no longer deadlocks.  Thanks,

      Btrfs: revert checksum error statistic which can cause a BUG() · 5ee0844d
      Stefan Behrens authored 
      Commit 442a4f63 added btrfs device
statistic counters for detected IO and checksum errors to Linux 3.5.
The statistic part that counts checksum errors in
end_bio_extent_readpage() can cause a BUG() in a subfunction:
"kernel BUG at fs/btrfs/volumes.c:3762!"
That part is reverted with the current patch.
However, the counting of checksum errors in the scrub context remains
active, and the counting of detected IO errors (read, write or flush
errors) in all contexts remains active.

      Btrfs: remove superblock writing after fatal error · 68ce9682
      Stefan Behrens authored 
      With commit acce952b, btrfs was changed to flag the filesystem with
BTRFS_SUPER_FLAG_ERROR and switch to read-only mode after a fatal
error happened like a write I/O errors of all mirrors.
In such situations, on unmount, the superblock is written in
btrfs_error_commit_super(). This is done with the intention to be able
to evaluate the error flag on the next mount. A warning is printed
in this case during the next mount and the log tree is ignored.

The issue is that it is possible that the superblock points to a root
that was not written (due to write I/O errors).
The result is that the filesystem cannot be mounted. btrfsck also does
not start and all the other btrfs-progs tools fail to start as well.
However, mount -o recovery is working well and does the right things
to recover the filesystem (i.e., don't use the log root, clear the
free space cache and use the next mountable root that is stored in the
root backup array).

This patch removes the writing of the superblock when
BTRFS_SUPER_FLAG_ERROR is set, and removes the handling of the error
flag in the mount function.

These lines can be used to reproduce the issue (using /dev/sdm):
SCRATCH_DEV=/dev/sdm
SCRATCH_MNT=/mnt
echo 0 25165824 linear $SCRATCH_DEV 0 | dmsetup create foo
ls -alLF /dev/mapper/foo
mkfs.btrfs /dev/mapper/foo
mount /dev/mapper/foo $SCRATCH_MNT
echo bar > $SCRATCH_MNT/foo
sync
echo 0 25165824 error | dmsetup reload foo
dmsetup resume foo
ls -alF $SCRATCH_MNT
touch $SCRATCH_MNT/1
ls -alF $SCRATCH_MNT
sleep 35
echo 0 25165824 linear $SCRATCH_DEV 0 | dmsetup reload foo
dmsetup resume foo
sleep 1
umount $SCRATCH_MNT
btrfsck /dev/mapper/foo
dmsetup remove foo
