PM / Hibernate: Fix PM_POST_* notification with user-space suspend

2011-01-07T21:58:19+00:00

commit 1497dd1d29c6a53fcd3c80f7ac8d0e0239e7389e upstream.

The user-space hibernation sends a wrong notification after the image
restoration because of thinko for the file flag check.  RDONLY
corresponds to hibernation and WRONLY to restoration, confusingly.

PM / Hibernate: Fix memory corruption related to swap

2010-12-09T21:33:26+00:00

commit c9e664f1fdf34aa8cede047b206deaa8f1945af0 upstream.

There is a problem that swap pages allocated before the creation of
a hibernation image can be released and used for storing the contents
of different memory pages while the image is being saved.  Since the
kernel stored in the image doesn't know of that, it causes memory
corruption to occur after resume from hibernation, especially on
systems with relatively small RAM that need to swap often.

This issue can be addressed by keeping the GFP_IOFS bits clear
in gfp_allowed_mask during the entire hibernation, including the
saving of the image, until the system is finally turned off or
the hibernation is aborted.  Unfortunately, for this purpose
it's necessary to rework the way in which the hibernate and
suspend code manipulates gfp_allowed_mask.

This change is based on an earlier patch from Hugh Dickins.

PM: earlysuspend: Removing dependence on console.

2010-09-30T00:49:08+00:00

Rather than signaling a full update of the display from userspace via a
console switch, this patch introduces 2 files int /sys/power,
wait_for_fb_sleep and wait_for_fb_wake.  Reading these files will block
until the requested state has been entered.  When a read from
wait_for_fb_sleep returns userspace should stop drawing.  When
wait_for_fb_wake returns, it should do a full update.  If either are called
when the fb driver is already in the requested state, they will return
immediately.
