      KASAN instrumentation poisons the stack when entering a function and
      unpoisons it when exiting the function.  However, in the suspend path,
      some functions never return, so their stack never gets unpoisoned,
      resulting in stale KASAN shadow data which can cause later false
      positive warnings like the one above.

      PM / sleep: System sleep state selection interface rework · 406e7938
      Rafael J. Wysocki authored
      There are systems in which the platform doesn't support any special
      sleep states, so suspend-to-idle (PM_SUSPEND_FREEZE) is the only
      available system sleep state.  However, some user space frameworks
      only use the "mem" and (sometimes) "standby" sleep state labels, so
      the users of those systems need to modify user space in order to be
      able to use system suspend at all and that may be a pain in practice.
      
      Commit 0399d4db (PM / sleep: Introduce command line argument for
      sleep state enumeration) attempted to address this problem by adding
      a command line argument to change the meaning of the "mem" string in
      /sys/power/state to make it trigger suspend-to-idle (instead of
      suspend-to-RAM).
      
      However, there also are systems in which the platform does support
      special sleep states, but suspend-to-idle is the preferred one anyway
      (it even may save more energy than the platform-provided sleep states
      in some cases) and the above commit doesn't help in those cases.
      
      For this reason, rework the system sleep state selection interface
      again (but preserve backwards compatibiliby).  Namely, add a new
      sysfs file, /sys/power/mem_sleep, that will control the system
      suspend mode triggered by writing "mem" to /sys/power/state (in
      analogy with what /sys/power/disk does for hibernation).  Make it
      select suspend-to-RAM ("deep" sleep) by default (if supported) and
      fall back to suspend-to-idle ("s2idle") otherwise and add a new
      command line argument, mem_sleep_default, allowing that default to
      be overridden if need be.
      
      At the same time, drop the relative_sleep_states command line
      argument that doesn't make sense any more.

      PM / hibernate: Verify the consistent of e820 memory map by md5 digest · 62a03def
      Chen Yu authored
      On some platforms, there is occasional panic triggered when
      trying to resume from hibernation, a typical panic looks like:
      
      "BUG: unable to handle kernel paging request at ffff880085894000
      IP: [<ffffffff810c5dc2>] load_image_lzo+0x8c2/0xe70"
      
      Investigation carried out by Lee Chun-Yi shows that this is because
      e820 map has been changed by BIOS across hibernation, and one
      of the page frames from suspend kernel is right located in restore
      kernel's unmapped region, so panic comes out when accessing unmapped
      kernel address.
      
      In order to expose this issue earlier, the md5 hash of e820 map
      is passed from suspend kernel to restore kernel, and the restore
      kernel will terminate the resume process once it finds the md5
      hash are not the same.
      
      As the format of image header has been modified, the magic number
      should also be adjusted as kernels with the same RESTORE_MAGIC have
      to use the same header format and interpret all of the fields in
      it in the same way.
      
      If the suspend kernel is built without md5 support, and the restore
      kernel has md5 support, then the latter will bypass the check process.
      Vice versa the restore kernel will bypass the check if it does not
      support md5 operation.
      
      Note:
      1. Without this patch applied, it is possible that BIOS has
         provided an inconsistent memory map, but the resume kernel is still
         able to restore the image anyway(e.g, E820_RAM region is the superset
         of the previous one), although the system might be unstable. So this
         patch tries to treat any inconsistent e820 as illegal.
      
      2. Another case is, this patch replies on comparing the e820_saved, but
         currently the e820_save might not be strictly the same across
         hibernation, even if BIOS has provided consistent e820 map - In
         theory mptable might modify the BIOS-provided e820_saved dynamically
         in early_reserve_e820_mpc_new, which would allocate a buffer from
         E820_RAM, and marks it from E820_RAM to E820_RESERVED).
         This is a potential and rare case we need to deal with in OS in
         the future.

        The main problem with this change got fixed already, but we missed the
        case where the local APIC is not yet mapped, when prefill_possible_map()
        is invoked, so the registration of the boot cpu which has the APIC bit
        set in CPUID will explode.
      
        I should have seen that issue earlier, but all I can do now is feeling

      x86/smpboot: Init apic mapping before usage · 1e90a13d
      Thomas Gleixner authored
      The recent changes, which forced the registration of the boot cpu on UP
      systems, which do not have ACPI tables, have been fixed for systems w/o
      local APIC, but left a wreckage for systems which have neither ACPI nor
      mptables, but the CPU has an APIC, e.g. virtualbox.
      
      The boot process crashes in prefill_possible_map() as it wants to register
      the boot cpu, which needs to access the local apic, but the local APIC is
      not yet mapped.
      
      There is no reason why init_apic_mapping() can't be invoked before
      prefill_possible_map(). So instead of playing another silly early mapping
      game, as the ACPI/mptables code does, we just move init_apic_mapping()
      before the call to prefill_possible_map().
      
      In hindsight, I should have noticed that combination earlier.
      
      Sorry for the churn (also in stable)!
