The free space tree format conversion functions were broken on
big-endian systems, but the sanity tests didn't catch it because all of
the operations were aligned to multiple words. This was meant to catch
any bugs in the extent buffer code's handling of high memory, but it
ended up hiding the endianness bug. Expand the tests to do both
sector-aligned and page-aligned operations.

The in-memory bitmap code manipulates words and is therefore sensitive
to endianness, while the extent buffer bitmap code addresses bytes and
is byte-order agnostic. Because the byte addressing of the extent buffer
bitmaps is equivalent to a little-endian in-memory bitmap, the extent
buffer bitmap tests fail on big-endian systems.
34b3e6c92af1 ("Btrfs: self-tests: Fix extent buffer bitmap test fail on
BE system") worked around another endianness bug in the tests but missed
this one because ed9e4afdb055 ("Btrfs: self-tests: Execute page
straddling test only when nodesize < PAGE_SIZE") disables this part of
the test on ppc64. That change lost the original meaning of the test,
however. We really want to test that an equivalent series of operations
using the in-memory bitmap API and the extent buffer bitmap API produces
equivalent results.
To fix this, don't use memcmp_extent_buffer() or write_extent_buffer();
do everything bit-by-bit.

There are two separate issues that can lead to corrupted free space
trees.
1. The free space tree bitmaps had an endianness issue on big-endian
systems which is fixed by an earlier patch in this series.
2. btrfs-progs before v4.7.3 modified filesystems without updating the
free space tree.
To catch both of these issues at once, we need to force the free space
tree to be rebuilt. To do so, add a FREE_SPACE_TREE_VALID compat_ro bit.
If the bit isn't set, we know that it was either produced by a broken
big-endian kernel or may have been corrupted by btrfs-progs.
This also provides us with a way to add rudimentary read-write support
for the free space tree to btrfs-progs: it can just clear this bit and
have the kernel rebuild the free space tree.

We moved the code for creating the free space tree the first time that
it's enabled, but didn't move the clearing code along with it. This
breaks my (undocumented) intention that `mount -o
clear_cache,space_cache=v2` would clear the free space tree and then
recreate it.

In convert_free_space_to_{bitmaps,extents}(), we buffer the free space
bitmaps in memory and copy them directly to/from the extent buffers with
{read,write}_extent_buffer(). The extent buffer bitmap helpers use byte
granularity, which is equivalent to a little-endian bitmap. This means
that on big-endian systems, the in-memory bitmaps will be written to
disk byte-swapped. To fix this, use byte-granularity for the bitmaps in
memory.

Pull power management updates from Rafael Wysocki:
"Traditionally, cpufreq is the area with the greatest number of
changes, but there are fewer of them than last time. There also is
some activity in the generic power domains and the devfreq frameworks,
a couple of system suspend and hibernation fixes and some assorted
changes in other places.
One new feature is the cpufreq change to allow the scheduler to pass
hints to the governors' utilization update callbacks and some code
rework based on that. Another one is the support for domain removal in
the generic power domains framework. Also it is now possible to use
hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the
RockChip DFI controller and the rk3399 DMC.
The rest of the changes is mostly fixes and cleanups in a number of
places.
Specifics:
- Add a mechanism for passing hints from the scheduler to cpufreq
governors via their utilization update callbacks and use it to
introduce "IOwait boosting" into the schedutil governor and
intel_pstate that will make them boost performance if the enqueued
task was previously waiting on I/O (Rafael Wysocki).
- Fix a schedutil governor problem that causes it to overestimate
utilization if SMT is in use (Steve Muckle).
- Update defconfigs trying to use the schedutil governor as a module
which is not possible any more (Javier Martinez Canillas).
- Update the intel_pstate's pstate_sample tracepoint to take "IOwait
boosting" into account (Srinivas Pandruvada).
- Fix a problem in the cpufreq core causing it to mishandle the
initialization of CPUs registered after the cpufreq driver (Viresh
Kumar, Rafael Wysocki).
- Make the cpufreq-dt driver support per-policy governor tunables,
clean it up and update its Kconfig description (Viresh Kumar).
- Add support for more ARM platforms to the cpufreq-dt driver
(Chanwoo Choi, Dave Gerlach, Geert Uytterhoeven).
- Make the cpufreq CPPC driver report frequencies in KHz to avoid
user space compatiblility issues (Al Stone, Hoan Tran).
- Clean up a few cpufreq drivers (st, kirkwood, SCPI) a bit (Colin
Ian King, Markus Elfring).
- Constify some local structures in the intel_pstate driver (Julia
Lawall).
- Add a Documentation/cpu-freq/ entry to MAINTAINERS (Jean Delvare).
- Add support for PM domain removal to the generic power domains
(genpd) framework, add new DT helper functions to it and make it
always enable debugfs support if available (Jon Hunter, Tomeu
Vizoso).
- Clean up the generic power domains (genpd) framework and make it
avoid measuring power-on and power-off latencies during system-wide
PM transitions (Ulf Hansson).
- Add support for the RockChip DFI controller and the rk3399 DMC to
the devfreq framework (Lin Huang, Axel Lin, Arnd Bergmann).
- Add COMPILE_TEST to the devfreq framework (Krzysztof Kozlowski,
Stephen Rothwell).
- Fix a minor issue in the exynos-ppmu devfreq driver and fix up
devfreq Kconfig indentation style (Wei Yongjun, Jisheng Zhang).
- Fix the system suspend interface to make suspend-to-idle work if
platform suspend operations have not been registered (Sudeep
Holla).
- Make it possible to use hibernation with PAGE_POISONING_ZERO
enabled (Anisse Astier).
- Increas the default timeout of the system suspend/resume watchdog
and make it depend on EXPERT (Chen Yu).
- Make the operating performance points (OPP) framework avoid using
OPPs that aren't supported by the platform and fix a build warning
in it (Dave Gerlach, Arnd Bergmann).
- Fix the ARM cpuidle driver's return value (Christophe Jaillet).
- Make the SmartReflex AVS (Adaptive Voltage Scaling) driver use more
common logging style (Joe Perches)"

Every time we allocate or free a data extent, we might need to split
the refcount btree. Reserve some blocks in the transaction to handle
this possibility. Even though the deferred refcount code can roll a
transaction to avoid overloading the transaction, we can still exceed
the reservation.
Certain pathological workloads (1k blocks, no cowextsize hint, random
directio writes), cause a perfect storm wherein a refcount adjustment
of a large range of blocks causes full tree splits in two separate
extents in two separate refcount tree blocks; allocating new refcount
tree blocks causes rmap btree splits; and all the allocation activity
causes the freespace btrees to split, blowing the reservation.
