The hibernate memory preallocation code allocates memory to push some user space data out of physical RAM, so that the hibernation image is not too large. It allocates more memory than necessary for creating the image, so it has to release some pages to make room for allocations made while suspending devices and disabling nonboot CPUs, or the system will hang due to the lack of free pages to allocate from. Unfortunately, the function used for freeing these pages, free_unnecessary_pages(), contains a bug that prevents it from doing the job on all systems without highmem. Fix this problem, which is a regression from the 2.6.30 kernel, by using the right condition for the termination of the loop in free_unnecessary_pages(). Signed-off-by: Rafael J.
