21a8122ad3 drm/radeon/kms: add support for internal thermal sensors (v3)
rv6xx/rv7xx/evergreen families supported; older asics did
not have an internal thermal sensor.

Note, not all oems use the internal thermal sensor, so it's
only exposed in cases where it is used.

Note also, that most laptops use an oem specific ACPI solution for
GPU thermal information rather than using the internal thermal
sensor directly.

v2: export millidegrees celsius, use hwmon device properly.
v3: fix Kconfig

Make the following changes to prepare for NCQ command completion

* mv_process_crpb_response(): restructure if clause for easier update.

* nv_adma_interrupt(): drop unnecessary error variable.

* nv_swncq_sdbfis(): drop unnecessary nr_done and return 0 on success.
  Typo fix.

213373cf97 ata_piix: fix locking around SIDPR access
SIDPR window registers are shared across ports and as each access is
done in two steps, accesses to different ports under EH may race.
This primarily is caused by incorrect host locking in EH context and
should be fixed by defining locking requirements for each EH operation
which can be used during EH and enforcing them but for now work around
the problem by adding a dedicated SIDPR lock and grabbing it for each
SIDPR access.

da10a2002c ahci_platform: Remove unneeded ahci_driver.probe assignment
The driver is using platform_driver_probe() during initialization,
so ahci_driver.probe hook is never used.

But it causes the following (harmless, luckily) section mismatch:

  WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference
  from the variable ahci_driver to the function .init.text:ahci_probe()

This patch removes the ahci_driver.probe assignment, thus fixes
the warning.

p.s. Note that there's another patch[1] from Rene Bolldorf that
tried to solve the same issue by __refdata annotation. __refdata
says that this reference is actually OK, but in fact it is not OK,
because dereferencing .probe() will cause problems. So the proper
fix is to remove the assignment.

880d22f247 perf: New migration tool overview
This brings a GUI tool that displays an overview of the load
of tasks proportion in each CPUs.

The CPUs forward progress is cut in timeslices. A new timeslice
is created for every runqueue event: a task gets pushed out or
pulled in the runqueue.

For each timeslice, every CPUs rectangle is colored with a red
power that describes the local load against the total load.
This more red is the rectangle, the higher is the given CPU load.
This load is the number of tasks running on the CPU, without
any distinction against the scheduler policy of the tasks, for
now.

Also for each timeslice, the event origin is depicted on the
CPUs that triggered it using a thin colored line on top of the
rectangle timeslice.

These events are:

* sleep: a task went to sleep and has then been pulled out the
  runqueue. The origin color in the thin line is dark blue.

* wake up: a task woke up and has then been pushed in the
  runqueue. The origin color is yellow.

* wake up new: a new task woke up and has then been pushed in the
  runqueue. The origin color is green.

* migrate in: a task migrated in the runqueue due to a load
  balancing operation. The origin color is violet.

* migrate out: reverse of the previous one. Migrate in events
  usually have paired migrate out events in another runqueue.
  The origin color is light blue.

Clicking on a timeslice provides the runqueue event details
and the runqueue state.

The CPU rectangles can be navigated using the usual arrow
controls. Horizontal zooming in/out is possible with the
"+" and "-" buttons.

0c2daaafcd powerpc/5200/i2c: improve i2c bus error recovery
This patch improves the recovery of the MPC's I2C bus from errors like bus
hangs resulting in timeouts:
1. make the bus timeout configurable, as it depends on the bus clock and
    the attached slave chip(s); default is still 1 second;
2. detect any of the cases indicated by the CF, BB and RXAK MSR flags if a
    timeout occurs, and add a missing (required) MAL reset;
3. use a more reliable method to fixup the bus if a hang has been detected.
    The sequence is sent 9 times which seems to be necessary if a slave
    "misses" more than one clock cycle.  For 400 kHz bus speed, the fixup is
    also ~70us (81us vs. 150us) faster.

Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors
and NXP IO expander chips attached to the i2c.

Changes vs. v1:
- use improved bus fixup sequence for all chips (not only the 5200)
- calculate real clock from defaults if no clock is given in the device tree
- better description (I hope) of the changes.

I didn't split the changes in this file into three parts as recommended by
Grant, as they actually belong together (i.e. they address one single
problem, just in three places of one single source file).

0d9dab39fb powerpc/5121: fsl-diu-fb: fix issue with re-enabling DIU area descriptor
On MPC5121e Rev 2.0 re-configuring the DIU area descriptor
by writing new descriptor address doesn't always work.
As a result, DIU continues to display using old area descriptor
even if the new one has been written to the descriptor register of
the plane.

Add the code from Freescale MPC5121EADS BSP for writing descriptor
addresses properly. This fixes the problem for Rev 2.0 silicon.

nfs_commit_inode() needs to be defined irrespectively of whether or not
we are supporting NFSv3 and NFSv4.

Allow the compiler to optimise away code in the NFSv2-only case by
converting it into an inlined stub function.

437f88cc03 ext4: fix freeze deadlock under IO
Commit 6b0310fbf0 caused a regression resulting in deadlocks
when freezing a filesystem which had active IO; the vfs_check_frozen
level (SB_FREEZE_WRITE) did not let the freeze-related IO syncing
through.  Duh.

Changing the test to FREEZE_TRANS should let the normal freeze
syncing get through the fs, but still block any transactions from
starting once the fs is completely frozen.

I tested this by running fsstress in the background while periodically
snapshotting the fs and running fsck on the result.  I ran into
occasional deadlocks, but different ones.  I think this is a
fine fix for the problem at hand, and the other deadlocky things
will need more investigation.
