The file Documentation/power/freezing-of-tasks.txt was still referencing
the TIF_FREEZE flag, that was removed by the commit
d88e4cb67197d007fb778d62fe17360e970d5bfa(freezer: remove now unused
TIF_FREEZE).

This patch removes all the references of TIF_FREEZE that were left
behind.

<title>PM / Freezer / Docs: Document the beauty of freeze/thaw semantics</title>

<content type='text'>
The way the different freeze/thaw functions encapsulate each other are quite
lovely from a design point of view. And as a side-effect, the way in which
they are invoked (cleaning up on failure for example) differs significantly
from how usual functions are dealt with. This is because of the underlying
semantics that govern the freezing and thawing of various tasks.

This subtle aspect that differentiates these functions from the rest, is
worth documenting.

Many thanks to Tejun Heo for providing enlightenment on this topic.

<title>PM / Sleep: Introduce "late suspend" and "early resume" of devices</title>

<link rel='alternate' type='text/html' href='https://git.stealer.net/cgit.cgi/user/sven/linux.git/commit/?id=cf579dfb82550e34de7ccf3ef090d8b834ccd3a9'/>
<id>urn:sha1:cf579dfb82550e34de7ccf3ef090d8b834ccd3a9</id>
<content type='text'>
The current device suspend/resume phases during system-wide power
transitions appear to be insufficient for some platforms that want
to use the same callback routines for saving device states and
related operations during runtime suspend/resume as well as during
system suspend/resume.  In principle, they could point their
.suspend_noirq() and .resume_noirq() to the same callback routines
as their .runtime_suspend() and .runtime_resume(), respectively,
but at least some of them require device interrupts to be enabled
while the code in those routines is running.

It also makes sense to have device suspend-resume callbacks that will
be executed with runtime PM disabled and with device interrupts
enabled in case someone needs to run some special code in that
context during system-wide power transitions.

Apart from this, .suspend_noirq() and .resume_noirq() were introduced
as a workaround for drivers using shared interrupts and failing to
prevent their interrupt handlers from accessing suspended hardware.
It appears to be better not to use them for other porposes, or we may
have to deal with some serious confusion (which seems to be happening
already).

For the above reasons, introduce new device suspend/resume phases,
"late suspend" and "early resume" (and analogously for hibernation)
whose callback will be executed with runtime PM disabled and with
device interrupts enabled and whose callback pointers generally may
point to runtime suspend/resume routines.

In a paragraph, "kernel thread" is mistakenly written as "kernel". Fix this by
adding thread after word "kernel".

Changes are shown in multiple lines, as they are realigned to 80 col width.

Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide
in-suspend monitoring.

This patch allows to monitor battery health in-suspend state.
