[RFC][PATCH 0/6] xtime/wall_to_monotonic cleanups
This patchset cleans up all the direct accesses to xtime and wall_to_monotonic, allowing them to be made static so we can do further cleanup and rework of the timekeeping core. This is 2.6.36 (or later) material. But I wanted to get the ball rolling. Any feedback/testing would be greatly appreciated! than... 4 Jun 2010 23:33

Proposal for a new algorithm for reading & writing a hibernation image.
Hi again. As I think about this more, I reckon we could run into problems at resume time with reloading the image. Even if some bits aren't modified as we're writing the image, they still might need to be atomically restored. If we make the atomic restore part too small, we might not be able to do that.
