It allocates more memory than necessary for creating\nthe image, so it has to release some pages to make room for\nallocations made while suspending devices and disabling nonboot CPUs,\nor the system will hang due to the lack of free pages to allocate\nfrom.

This may be improved by using\nhighmem for saving the contents of saveable highmem pages.\n\nNamely, during the suspend phase of the suspend-resume cycle we try to\nallocate as many free highmem pages as there are saveable highmem pages.\nIf there are not enough highmem image pages to store the contents of all of\nthe saveable highmem pages, some of them will be stored in the \"normal\"\nmemory. Next, we allocate as many free \"normal\" pages as needed to store\nthe (remaining) image data. We use a memory bitmap to mark the allocated\nfree pages (ie. highmem as well as \"normal\" image pages).\n\nNow, we use another memory bitmap to mark all of the saveable pages\n(highmem as well as \"normal\") and the contents of the saveable pages are\ncopied into the image pages. Then, the second bitmap is used to save the\npfns corresponding to the saveable pages and the first one is used to save\ntheir data.\n\nDuring the resume phase the pfns of the pages that were saveable during the\nsuspend are loaded from the image and used to mark the \"unsafe\" page\nframes. Next, we try to allocate as many free highmem page frames as to\nload all of the image data that had been in the highmem before the suspend\nand we allocate so many free \"normal\" page frames that the total number of\nallocated free pages (highmem and \"normal\") is equal to the size of the\nimage. While doing this we have to make sure that there will be some extra\nfree \"normal\" and \"safe\" page frames for two lists of PBEs constructed\nlater.\n\nNow, the image data are loaded, if possible, into their \"original\" page\nframes. The image data that cannot be written into their \"original\" page\nframes are loaded into \"safe\" page frames and their \"original\" kernel\nvirtual addresses, as well as the addresses of the \"safe\" pages containing\ntheir copies, are stored in one of two lists of PBEs.\n\nOne list of PBEs is for the copies of \"normal\" suspend pages (ie. \"normal\"\npages that were saveable during the suspend) and it is used in the same way\nas previously (ie. by the architecture-dependent parts of swsusp). The\nother list of PBEs is for the copies of highmem suspend pages. The pages\nin this list are restored (in a reversible way) right before the\narch-dependent code is called.\n\nSigned-off-by: Rafael J.

For this\nreason the memory bitmap structure consists of several linked lists of objects\nthat contain pointers to memory pages with the actual bitmap data. Still, for\na typical system all of these lists fit in a single page, so it\u0027s reasonable\nto introduce an additional mechanism allowing us to allocate all of them\nefficiently without sacrificing the generality of the design. This is done\nwith the help of the chain_allocator structure and associated functions.\n\nWe need to use two memory bitmaps during the suspend phase of the\nsuspend-resume cycle. One of them is necessary for marking the saveable\npages, and the second is used to mark the pages in which to store the copies\nof them (aka image pages).\n\nFirst, the bitmaps are created and we allocate as many image pages as needed\n(the corresponding bits in the second bitmap are set as soon as the pages are\nallocated).
