but there are others too (i.MX, Tegra, ep93xx). Fixes warnings, some
broken platforms and drivers, etc. A bit all over the map really.

"This is a batch of fixes for arm-soc platforms, most of it is for OMAP
but there are others too (i.MX, Tegra, ep93xx). Fixes warnings, some
broken platforms and drivers, etc. A bit all over the map really."
There was some concern about commit 68136b10 ("RM: sunxi: Change device
tree naming scheme for sunxi"), but Tony says:
"Looks like that's trivial to fix as needed, no need to rebuild the
branch to fix that AFAIK.
The fix can be done once Olof is available online again.
Linus, I suggest that you go ahead and pull this if there are no other
issues with this branch."

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.

But since mapping might require sleeping, this implies mutex in use

Like the generic versions, we need to support a block size

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.
Signed-off-by: David S. Miller <davem@davemloft.net>
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.
This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

Extend support for reporting and selecting PECI temperature sensors
to IT8718, IT8720, IT8782, and IT8783. For IT8721, report the sensor
type for temp2 as Intel PECI (6) if the chip is configured to report
the PCH temperature.

IT8721 and IT8728 support Intel PECI temperature reporting. Each sensor
can be programmed to display the temperature reported on the PECI interface.
If configured for Intel PECI, the driver reported the wrong sensor type for
the respective thermal sensor. Fix the code to correctly report it as
"Intel PECI (6)".

The macro name show_sensor_offset is confusing since it related to the sensor
type, not an offset - even more so when we introduce offset attributes later on.
Replace it with direct definitions, and replace the show_sensor/set_sensor
function names with show_temp_type/set_temp_type. This also resolves a
checkpatch error.

The smatch static code analyzer complains:
drivers/hwmon/w83627ehf.c:911 w83627ehf_update_device() error: buffer overflow 'W83627EHF_REG_TEMP_OFFSET' 3 <= 8
drivers/hwmon/w83627ehf.c:909 w83627ehf_update_device() error: buffer overflow 'data->temp_offset' 3 <= 8
drivers/hwmon/w83627ehf.c:2672 w83627ehf_resume() error: buffer overflow 'W83627EHF_REG_TEMP_OFFSET' 3 <= 8
drivers/hwmon/w83627ehf.c:2673 w83627ehf_resume() error: buffer overflow 'data->temp_offset' 3 <= 8
A deeper analysis of the code shows that these are false positives, as
only the lower 3 bits of data->have_temp_offset can be set so the
write is never attempted with i >= 3. However this shows that the code
isn't very robust and future changes could easily introduce a buffer
overflow. So let's add a safety check to prevent that and make smatch
happy.

Only the W83627HF could be accessed through I2C. All other supported
chips are LPC-only, so they do not have I2C address registers. Don't
write to nonexistent or reserved registers on these chips.

On suspend some register values are lost, most notably the Value RAM
areas but also other limits. Restore them on resume. On top of that,
some fixups are needed to work around BIOS bugs, in particular when
the BIOS omits running the same initialization sequence on resume
that it does after boot. In that case we have to carry initialization
over suspend.
