Subject[BK PATCH] Power Management Updates

Linus,

Here is a set of Power Management changes that contain the changes Pavel
has been trying to push to you for a couple of weeks now. They have been
split up into individual changesets and hand merged to be a bit cleaner
than the original patches.

These also contain initial efforts to start cleaning up swsusp by
splitting out shareable functionality and moving the whole lot from
kernel/suspend.c into kernel/power/*.c.

The tree can be pulled from:

bk://kernel.bkbits.net/home/mochel/linux-2.5-power

The changesets are described below.

Individual patches can be viewed here:

http://developer.osdl.org/~mochel/patches/aug4/power/

I will not be sending them, as some of them are quite large (from moving
files/directories).

Pavel: please review and let me know if I missed anything important, so I
can (quickly) fix it up.

Thanks,


-pat

ChangeSet@1.1518, 2003-08-04 17:35:30-07:00, mochel@osdl.org
[power] Divorce suspend console code from swsusp.

- Create kernel/power/console.c
- Rename prepare_suspend_console() to pm_prepare_console() and
restore_console() to pm_restore_console().
- Add prototypes to include/linux/suspend.h.
- Make kernel/power/console.o dependent only on CONFIG_PM
- Simplify logic for SUSPEND_CONSOLE define
- Make software_resume() prepare console much earlier, so we can localize
the loglevel variables in console.c.
- Remove #ifdef CONFIG_VT from console.c, and just check for SUSPEND_CONSOLE.
(Perhaps we should make entire file dependent on CONFIG_VT_CONSOLE?)
- Add kernel/power/power.h to share things across local files.

[power] Minor swsusp cleanups.

- Call blk_run_queues() from do_software_suspend() directly, instead of
wrapping it in helper function.
- Get rid of ominous compiler warning.
- Change BUG_ON(in_interrupt()) to might_sleep() in software_suspend(), so
we still get back trace, but don't actually BUG().

Orginally from Pavel Machek.

[power] Fix up refrigerator to work with ^Z-ed processes

Originally from Pavel Machek:

schedule() added makes processes start at exactly that point, making
printouts nicer.
