      Pull audit updates from Paul Moore:
       "Another merge window, another small audit pull request.
      
        Four patches in total: one is cosmetic, one removes an unnecessary
        initialization, one renames some enum values to prevent name
        collisions, and one converts list_del()/list_add() to list_move().
      
        None of these are earth shattering and all pass the audit-testsuite
        tests while merging cleanly on top of your tree from earlier today"

         SELinux policydb.

         removal of useless LSM/XFRM function args, SELinux kdoc fixes, and

      Merge tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
      
      Pull openat2 fixes from Christian Brauner:
      
       - Remove the unused VALID_UPGRADE_FLAGS define we carried from an
         extension to openat2() that we haven't merged. Aleksa might be
         getting back to it at some point but just not right now.
      
       - openat2() used to accidently ignore unknown flag values in the upper
         32 bits.
      
         The new openat2() syscall verifies that no unknown O-flag values are
         set and returns an error to userspace if they are while the older
         open syscalls like open() and openat() simply ignore unknown flag
         values:
      
            #define O_FLAG_CURRENTLY_INVALID (1 << 31)
            struct open_how how = {
                  .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID,
                  .resolve = 0,
            };
      
            /* fails */
            fd = openat2(-EBADF, "/dev/null", &how, sizeof(how));
      
            /* succeeds */
            fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID);
      
         However, openat2() silently truncates the upper 32 bits meaning:
      
            #define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31)
            #define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40)
      
            struct open_how how_lowe32 = {
                  .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32,
            };
      
            struct open_how how_upper32 = {
                  .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32,
            };
      
            /* fails */
            fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32));
      
            /* succeeds */
            fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32));
      
         Fix this by preventing the immediate truncation in build_open_flags()
         and add a compile-time check to catch when we add flags in the upper
         32 bit range.

        flag via mount_setattr() and fsmount(). With mount_setattr() that flag
        can even be applied recursively.
      
        There's an additional ack from Ross Zwisler who originally authored
        the nosymfollow patch. As I've already had the patches in my for-next
        I didn't add his ack explicitly"

      qemu_fw_cfg: Make fw_cfg_rev_attr a proper kobj_attribute · fca41af1
      Nathan Chancellor authored
      fw_cfg_showrev() is called by an indirect call in kobj_attr_show(),
      which violates clang's CFI checking because fw_cfg_showrev()'s second
      parameter is 'struct attribute', whereas the ->show() member of 'struct
      kobj_structure' expects the second parameter to be of type 'struct
      kobj_attribute'.
      
      $ cat /sys/firmware/qemu_fw_cfg/rev
      3
      
      $ dmesg | grep "CFI failure"
      [   26.016832] CFI failure (target: fw_cfg_showrev+0x0/0x8):
      
      Fix this by converting fw_cfg_rev_attr to 'struct kobj_attribute' where
      this would have been caught automatically by the incompatible pointer
      types compiler warning. Update fw_cfg_showrev() accordingly.
      
      Fixes: 75f3e8e4 ("firmware: introduce sysfs driver for QEMU's fw_cfg device")

       "Time and clocksource/clockevent related updates:
      
        Core changes:
      
         - Infrastructure to support per CPU "broadcast" devices for per CPU
           clockevent devices which stop in deep idle states. This allows us
           to utilize the more efficient architected timer on certain ARM SoCs
           for normal operation instead of permanentely using the slow to
           access SoC specific clockevent device.
      
         - Print the name of the broadcast/wakeup device in /proc/timer_list
      
         - Make the clocksource watchdog more robust against delays between
           reading the current active clocksource and the watchdog
           clocksource. Such delays can be caused by NMIs, SMIs and vCPU
           preemption.
      
           Handle this by reading the watchdog clocksource twice, i.e. before
           and after reading the current active clocksource. In case that the
           two watchdog reads shows an excessive time delta, the read sequence
           is repeated up to 3 times.
      
         - Improve the debug output and add a test module for the watchdog
           mechanism.
      
         - Reimplementation of the venerable time64_to_tm() function with a
           faster and significantly smaller version. Straight from the source,
           i.e. the author of the related research paper contributed this!

           interrupt flow handlers when this invocation requires irqdomain
           resolution. Add the necessary core infrastructure.
      
         - Provide a proper interface for modular PMU drivers to set the

         - Add a request flag which allows to exclude interrupts from spurious
           interrupt detection. Useful especially for IPI handlers which
           always return IRQ_HANDLED which turns the spurious interrupt
           detection into a pointless waste of CPU cycles.

      Pull printk updates from Petr Mladek:
      
       - Add %pt[RT]s modifier to vsprintf(). It overrides ISO 8601 separator
         by using ' ' (space). It produces "YYYY-mm-dd HH:MM:SS" instead of
         "YYYY-mm-ddTHH:MM:SS".
      
       - Correctly parse long row of numbers by sscanf() when using the field
         width. Add extensive sscanf() selftest.
      
       - Generalize re-entrant CPU lock that has already been used to
         serialize dump_stack() output. It is part of the ongoing printk
         rework. It will allow to remove the obsoleted printk_safe buffers and
         introduce atomic consoles.
      
       - Some code clean up and sparse warning fixes.

      mm,hwpoison: make get_hwpoison_page() call get_any_page() · 0ed950d1
      Naoya Horiguchi authored
      __get_hwpoison_page() could fail to grab refcount by some race condition,
      so it's helpful if we can handle it by retrying.  We already have retry
      logic, so make get_hwpoison_page() call get_any_page() when called from
      memory_failure().
      
      As a result, get_hwpoison_page() can return negative values (i.e.  error
      code), so some callers are also changed to handle error cases.
      soft_offline_page() does nothing for -EBUSY because that's enough and
      users in userspace can easily handle it.  unpoison_memory() is also
      unchanged because it's broken and need thorough fixes (will be done
      later).
