PM/Hibernate: Do not release preallocated memory unnecessarily (rev. 2)
Since the hibernation code is now going to use allocations of memory to make enough room for the image, it can also use the page frames allocated at this stage as image page frames. The low-level hibernation code needs to be rearranged for this purpose, but it allows us to avoid freeing a great number of pages and allocating these same pages once again later, so it generally is worth doing. [rev. 2: Take highmem into account correctly.] Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
