bc is mentioned lower in a dedicated section.
Yet it is useful to have all dependencies listed in

Currently the encoding of documents generated by DocBook depends on
the current locale. Make the output reproducible independently of
the locale, by setting the encoding to UTF-8 (LC_CTYPE=C.UTF-8) by
preference, or ASCII (LC_CTYPE=C) as a fallback.
LC_CTYPE can normally be overridden by LC_ALL, but the top-level
Makefile unsets that.

For years I've waited in vain for Linus to see the error of his ways and go
back to our beloved 2.6.x naming scheme. But dispair has overtaken me at
last, so, with a heavy heart, I'm moving my repo to a more contemporary
name. My kids will be proud of me.

The gpiolib supports parsing DT properties of the form <function>-gpio
but it was only added for compatibility with older DT bindings that got
it wrong and should not be used in newer bindings.
The commit that added support for this was:
dd34c37aa3 ("gpio: of: Allow -gpio suffix for property names")
but didn't update the documentation to explain this so it's been a source
of confusion. So let's make clear this in the GPIO documentation.

The nents argument to the DMA API functions operating on scatterlists is
always the same. The documentation used different argument names and the
matter was not mentioned in Documentation/DMA-API-HOWTO.txt at all. Fix
these.

Several documentation changes.
First, we never mentioned any errors and never required any
error checks in documentation.
Second, mention that there is another way to configure and
manage zram devices -- zramctl, provided by util-linux.
Third, add a bit of clarification on why `mem_used_max' attr
is RW and correct some typos.

"A disappointingly large collection of fixes for SPI issues, though
almost all in drivers (and there mainly the newly added Mediatek
driver) and the core fixes are documentation and error handling.
The driver fixes are all of the usual 'important if you see them'
variety"

"Two stable@ fixes:
- DM thinp fix to properly advertise discard support as disabled for
thin devices backed by a thin-pool with discard support disabled.
- DM crypt fix to prevent the creation of bios that violate the
underlying block device's max_segments limits. This fixes a
relatively long-standing NCQ SSD corruption issue reported against
dm-crypt ever since the dm-crypt cpu parallelization patches were
merged back in 4.0"

Pull cgroup fixes from Tejun Heo:
"The threadgroup locking changes which went in during 4.2 devel cycle
added write locking of a percpu_rwsem in cgroup task migration path;
unfortunately, that involved expedited rcu syncing which turned out to
be too slow and heavy for certain workloads. The patchset which is
dependent on this one didn't get committed during that devel cycle, so
these two patches can be reverted safely.
Oleg reworked percpu_rwsem for 4.4 so that the writer path is a lot
lighter. The reported issue goes away with Oleg's reworked
percpu_rwsem and I'll reapply these patches on the for-4.4 branch so
that they can land together with Oleg's changes"
