Namely, in that cases we need\nto disable the GPEs before replacing the \"boot\" kernel with the \"frozen\"\nkernel (cf. http://bugzilla.kernel.org/show_bug.cgi?id\u003d7887). After the\nrestore they will be re-enabled by hibernation_ops-\u003efinish(), but if the\nrestore fails, they have to be re-enabled by the restore code explicitly.\n\nFor this purpose we can introduce two additional hibernation operations,\ncalled pre_restore() and restore_cleanup() and call them from the restore code\npath. Still, they should be called if the \"platform\" mode of hibernation has\nbeen used, so we need to pass the information about the hibernation mode from\nthe \"frozen\" kernel to the \"boot\" kernel in the image header.\n\nApparently, we can\u0027t drop the disabling of GPEs before the restore because of\nBug #7887 .  We also can\u0027t do it unconditionally, because the GPEs wouldn\u0027t\nhave been enabled after a successful restore if the suspend had been done in\nthe \u0027shutdown\u0027 or \u0027reboot\u0027 mode.\n\nIn principle we could (and probably should) unconditionally disable the GPEs\nbefore each snapshot creation *and* before the restore, but then we\u0027d have to\nunconditionally enable them after the snapshot creation as well as after the\nrestore (or restore failure)   Still, for this purpose we\u0027d need to modify\nacpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we\u0027d have to\nintroduce some mechanism synchronizing the disablind/enabling of the GPEs with\nthe device drivers\u0027 .suspend()/.resume() routines and with\ndisable_/enable_nonboot_cpus().  However, this would have affected the\nsuspend (ie. s2ram) code as well as the hibernation, which I\u0027d like to avoid\nin this patch series.\n\nSigned-off-by: Rafael J.

Subsequently, the image is loaded and, if\npossible, the data loaded from it are written into their \"original\" page\nframes (ie. the ones they had occupied before the suspend).\n\nThe image data that cannot be written into their \"original\" page frames are\nloaded into \"safe\" page frames and their \"original\" kernel virtual addresses,\nas well as the addresses of the \"safe\" pages containing their copies, are\nstored in a list of PBEs. Finally, the list of PBEs is used to copy the\nremaining image data into their \"original\" page frames (this is done\natomically, by the architecture-dependent parts of swsusp).\n\nSigned-off-by: Rafael J.

This is achieved by\ncreating a copy of the relevant page tables that will not be modified by\nswsusp and can be safely used by it on resume.\n\nThe problem is that during resume on x86-64 swsusp may temporarily\ncorrupt the page tables used for the direct mapping of RAM. If that\nhappens, a page fault occurs and cannot be handled properly, which leads\nto the solid hang of the affected system. This leads to the loss of the\nsystem\u0027s state from before suspend and may result in the loss of data or\nthe corruption of filesystems, so it is a serious issue. Also, it\nappears to happen quite often (for me, as often as 50% of the time).\n\nThe problem is related to the fact that (at least) one of the PMD\nentries used in the direct memory mapping (starting at PAGE_OFFSET)\npoints to a page table the physical address of which is much greater\nthan the physical address of the PMD entry itself. Moreover,\nunfortunately, the physical address of the page table before suspend\n(i.e. the one stored in the suspend image) happens to be different to\nthe physical address of the corresponding page table used during resume\n(i.e. the one that is valid right before swsusp_arch_resume() in\narch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is\nrestored, the \"offending\" PMD entry gets overwritten, so it does not\npoint to the right physical address any more (i.e. there\u0027s no page\ntable at the address pointed to by it, because it points to the address\nthe page table has been at during suspend). Consequently, if the PMD\nentry is used later on, and it _is_ used in the process of copying the\nimage pages, a page fault occurs, but it cannot be handled in the normal\nway and the system hangs.\n\nIn principle we can call create_resume_mapping() from\nswsusp_arch_resume() (ie. from suspend_asm.S), but then the memory\nallocations in create_resume_mapping(), resume_pud_mapping(), and\nresume_pmd_mapping() must be made carefully so that we use _only_\nNosaveFree pages in them (the other pages are overwritten by the loop in\nswsusp_arch_resume()). Additionally, we are in atomic context at that\ntime, so we cannot use GFP_KERNEL. Moreover, if one of the allocations\nfails, we should free all of the allocated pages, so we need to trace\nthem somehow.\n\nAll of this is done in the appended patch, except that the functions\npopulating the page tables are located in arch/x86_64/kernel/suspend.c\nrather than in init.c. It may be done in a more elegan way in the\nfuture, with the help of some swsusp patches that are in the works now.\n\n[AK: move some externs into headers, renamed a function]\n\nSigned-off-by: Rafael J.
