In contrast, the function returns NULL when THERMAL_OF is configured

If the default PM Domain using PM_CLK is used for PM runtime, the real
Clock Domain cannot be registered from DT later.
Hence do not enable it when running a multi-platform kernel with genpd
support on R-Car or RZ. The CPG/MSTP Clock Domain driver will take care
of PM runtime management of the module clocks.
Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile,
R-Car, RZ) use DT-based PM Domains to take care of PM runtime management
of the module clocks, simplify the platform logic by replacing the
explicit SoC checks by a single check for the presence of MSTP clocks in
DT.
Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided
by checking for the presence of a "#power-domain-cells" property in DT.
The default PM Domain is still needed for:
- backwards-compatibility with old DTs that lack PM Domain properties,
- the CONFIG_PM=n case,
- legacy (non-DT) ARM/shmobile platforms without genpd support
(r8a7778, r8a7779),
- legacy SuperH.

We discussed a bit with the folks on the Cc: list below what to do
with ION. Two big take-aways:
- High-performance drivers (like gpus) always want to play tricks with
coherency and will lie to the dma api (radeon, nouveau, i915 gpu
drivers all do so in upstream). What needs to be done here is fill
gaps in dma-buf so that we can do this without breaking the dma-api
expections of other clients like v4l. The consesus is that hw won't
stop needing these tricks anytime soon.
- Placement constraints for shared buffers won't be solved any other
way than through something platform-specific like ion with
platform-specific knowledge in userspace in something like gralloc.
For general-purpose devices where this assumption would be painful
for userspace (like servers) the consensus is that such devices will
have proper MMUs where placement constraint handling is fairly
irrelevant.
Hence it is reasonable to destage ion as-is without changing the
overall design to enable these use-cases and just fixing up a these
few fairly minor things. Since there won't relly be an open-source
userspace for ion (and hence drm maintainers won't take it) the
proposal is to eventually move it to drivers/android/ion.[hc]. Laura
would be ok with being maintainer once this is all done and ion is
destaged.
Note that Thiago is working on exposing the cpu cache flushing for
cpu access from userspace through mmaps so this is alread in progress.
Also adding him to the Cc: list.

After the conversion of pxa architecture to common clock framework, the
NAND clock can be disabled on startup if no nand driver claims it.
In this case, it happens that if the bootloader used the NAND and set
the DFI arbitration bit, the next access to a static memory controller
area, such as an ethernet card, the system bus will stall, and the core
will be stalled forever.
Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
will be enabled the pxa3xx-nand driver on need anyway. The only left
requirement is that upon pxa3xx-nand removal, the bit should be cleared
before the clock is disabled.

The internal clocksteering done for fine-grained error
correction uses a logarithmic approximation, so any time
adjtimex() adjusts the clock steering, timekeeping_freqadjust()
quickly approximates the correct clock frequency over a series
of ticks.
Unfortunately, the logic in timekeeping_freqadjust(), introduced
in commit:
dc491596f6 ("timekeeping: Rework frequency adjustments to work better w/ nohz")
used the abs() function with a s64 error value to calculate the
size of the approximated adjustment to be made.
Per include/linux/kernel.h:
"abs() should not be used for 64-bit types (s64, u64, long long) - use abs64()".
Thus on 32-bit platforms, this resulted in the clocksteering to
take a quite dampended random walk trying to converge on the
proper frequency, which caused the adjustments to be made much
slower then intended (most easily observed when large
adjustments are made).
This patch fixes the issue by using abs64() instead.

rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
a boolean value.
Now, admittedly the "!= 0" doesn't really change the value (0 stays as
zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
causes gcc to warn about the construct
switch (rq_data_dir(req)) {
case READ:
...
case WRITE:
...
that we have in a few drivers.
Now, the gcc warning is silly and stupid (it seems to warn not about the
switch value having a different type from the case statements, but about
_any_ boolean switch value), but in this case the code itself is silly
and stupid too, so let's just change it, and get rid of warnings like
this:
drivers/block/hd.c: In function ‘hd_request’:
drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
switch (rq_data_dir(req)) {
The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
commit 5953316dbf ("block: make rq->cmd_flags be 64-bit") and is
presumably because the old code (that just did a logical 'and' with 1)
would then end up making the type of rq_data_dir() be u64 too.
But if we want to retain the old regular integer type, let's just cast
the result to 'int' rather than use that rather odd '!= 0'.

Fix up the writeback plugging introduced in commit d353d7587d
("writeback: plug writeback at a high level") that then caused problems
due to the unplug happening with a spinlock held.
* writeback-plugging:
writeback: plug writeback in wb_writeback() and writeback_inodes_wb()
Revert "writeback: plug writeback at a high level"
We had to revert the pluggin in writeback_sb_inodes() because the
wb->list_lock is held, but we could easily plug at a higher level before
taking that lock, and unplug after releasing it. This does that.
Chris will run performance numbers, just to verify that this approach is
comparable to the alternative (we could just drop and re-take the lock
around the blk_finish_plug() rather than these two commits.
I'd have preferred waiting for actual performance numbers before picking
one approach over the other, but I don't want to release rc1 with the
known "sleeping function called from invalid context" issue, so I'll
pick this cleanup version for now. But if the numbers show that we
really want to plug just at the writeback_sb_inodes() level, and we
should just play ugly games with the spinlock, we'll switch to that.

thermal-intel branches was wrong.
In thermal-core, commit 17e8351a77 ("thermal: consistently use int for

But in parallel, in the thermal-intel branch commit d0a12625d2

PCH thermal sensor using the old interfaces that used "unsigned long"
pointers.
This resulted in warnings like this:

Pull more power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes and cleanups on top of the previous PM+ACPI
pull request (cpufreq core and drivers, cpuidle, generic power domains
framework). Some of them didn't make to that pull request and some
fix issues introduced by it.
The only really new thing is the support for suspend frequency in the
cpufreq-dt driver, but it is needed to fix an issue with Exynos
platforms.
Specifics:
- build fix for the new Mediatek MT8173 cpufreq driver (Guenter
Roeck).
- generic power domains framework fixes (power on error code path,
subdomain removal) and cleanup of a deprecated API user (Geert
Uytterhoeven, Jon Hunter, Ulf Hansson).
- cpufreq-dt driver fixes including two fixes for bugs related to the
new Operating Performance Points Device Tree bindings introduced
recently (Viresh Kumar).
- suspend frequency support for the cpufreq-dt driver (Bartlomiej
Zolnierkiewicz, Viresh Kumar).
- cpufreq core cleanups (Viresh Kumar).
- intel_pstate driver fixes (Chen Yu, Kristen Carlson Accardi).
- additional sanity check in the cpuidle core (Xunlei Pang).
- fix for a comment related to CPU power management (Lina Iyer)"

Commit 6b0f68e32e ("mm: add utility for early copy from unmapped ram")
introduces a function copy_from_early_mem() into mm/early_ioremap.c
which itself calls early_memremap()/early_memunmap(). However, since
early_memunmap() has not been declared yet at this point in the .c file,
nor by any explicitly included header files, we are depending on a
transitive include of asm/early_ioremap.h to declare it, which is
fragile.
So instead, include this header explicitly.

The seq_<foo> function return values were frequently misused.
See: commit 1f33c41c03 ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
All uses of these return values have been removed, so convert the
return types to void.
Miscellanea:
o Move seq_put_decimal_<type> and seq_escape prototypes closer the
other seq_vprintf prototypes
o Reorder seq_putc and seq_puts to return early on overflow
o Add argument names to seq_vprintf and seq_printf
o Update the seq_escape kernel-doc
o Convert a couple of leading spaces to tabs in seq_escape
