PM / Hibernate: Hibernate/thaw fixes/improvements
1. Do not allocate memory for buffers from emergency pools, unless
absolutely required. Do not warn about and do not retry non-essential
failed allocations.
2. Do not check the amount of free pages left on every single page
write, but wait until one map is completely populated and then check.
3. Set maximum number of pages for read buffering consistently, instead
of inadvertently depending on the size of the sector type.
4. Fix copyright line, which I missed when I submitted the hibernation
threading patch.
5. Dispense with bit shifting arithmetic to improve readability.
6. Really recalculate the number of pages required to be free after all
allocations have been done.
7. Fix calculation of pages required for read buffering. Only count in
pages that do not belong to high memory.
