help text: SOFTWARE_SUSPEND doesn't need ACPI

2006-03-31T23:03:08+00:00

The note that SOFTWARE_SUSPEND doesn't need APM is helpful, but nowadays
the information that it doesn't need ACPI, too, is even more helpful.

[PATCH] Fix suspend with traced tasks

2006-03-31T20:18:50+00:00

strace /bin/bash misbehaves after resume; this fixes it.

(akpm: it's scary calling refrigerator() in state TASK_TRACED, but it seems to
do the right thing).

[PATCH] swswsup: return correct load_image error

2006-03-26T16:56:55+00:00

If there's an error in load_image() we should return that without checking
snapshot_image_loaded.

[PATCH] Check if cpu can be onlined before calling smp_prepare_cpu()

2006-03-25T16:23:01+00:00

- Moved check for online cpu out of smp_prepare_cpu()

- Moved default declaration of smp_prepare_cpu() to kernel/cpu.c

- Removed lock_cpu_hotplug() from smp_prepare_cpu() to around it, since
  its called from cpu_up() as well now.

- Removed clearing from cpu_present_map during cpu_offline as it breaks
  using cpu_up() directly during a subsequent online operation.

Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

[PATCH] swsusp: add s2ram ioctl to userland interface

2006-03-23T15:38:08+00:00

Add the SNAPSHOT_S2RAM ioctl to the snapshot device.

This ioctl allows a userland application to make the system (previously frozen
with the SNAPSHOT_FREE ioctl) enter the S3 state without freezing processes
and disabling nonboot CPUs for the second time.

This will allow us to implement the suspend-to-disk-and-RAM (STDR)
functionality in the userland suspend tools.

interface and let the userland tools switch the console.

[PATCH] suspend: make progress printing prettier

2006-03-23T15:38:08+00:00

Combination of printk/pr_debug led to <7> in the middle of the line, and we
printed way too many dots.

[PATCH] swsusp: freeze user space processes first

2006-03-23T15:38:08+00:00

Allow swsusp to freeze processes successfully under heavy load by freezing
userspace processes before kernel threads.

[Thanks to Nigel Cunningham  for suggesting the
way to go.]
