      alarmtimer: Fix unavailable wake-up source in sysfs · 47b4a457
      Geert Uytterhoeven authored
      Currently the alarmtimer registers a wake-up source unconditionally,
      regardless of the system having a (wake-up capable) RTC or not.
      Hence the alarmtimer will always show up in
      /sys/kernel/debug/wakeup_sources, even if it is not available, and thus
      cannot be a wake-up source.
      
      To fix this, postpone registration until a wake-up capable RTC device is
      added.

      timekeeping: Use proper timekeeper for debug code · a529bea8
      Stafford Horne authored
      When CONFIG_DEBUG_TIMEKEEPING is enabled the timekeeping_check_update()
      function will update status like last_warning and underflow_seen on the
      timekeeper.
      
      If there are issues found this state is used to rate limit the warnings
      that get printed.
      
      This rate limiting doesn't really really work if stored in real_tk as
      the shadow timekeeper is overwritten onto real_tk at the end of every
      update_wall_time() call, resetting last_warning and other statuses.
      
      Fix rate limiting by using the shadow_timekeeper for
      timekeeping_check_update().

      kselftests: timers: set-timer-lat: Add one-shot timer test cases · 28be3f8f
      Greg Hackmann authored
      These testcases are motivated by a recent alarmtimer regression, which
      caused one-shot CLOCK_{BOOTTIME,REALTIME}_ALARM timers to become
      periodic timers.
      
      The new testcases are very similar to the existing testcases for
      repeating timers.  But rather than waiting for 5 alarms, they wait for 5
      seconds and verify that the alarm fired exactly once.

      kselftests: timers: set-timer-lat: Tweak reporting when timer fires early · a524b118
      Greg Hackmann authored
      Rather than printing an error inside the alarm signal handler, set a
      flag that we check later.  This keeps the test from spamming the console
      every time the alarm fires early.  It also fixes the test exiting with
      error code 0 if this was the only test failure.

         - Fix race on setting and getting cpu_online_mask
      
         - Fix preemption issue. To do so cleanly introduce macro to get the
           size of L3 cache line.
      
         - Revert include cleanup that sometimes results in build error
      
         - MicroMIPS uses bit 0 of the PC to indicate microMIPS mode. Make
           sure this bit is set for kernel entry as well.
      
         - Prevent configuring the kernel for both microMIPS and MT. There are
           no such CPUs currently and thus the combination is unsupported and
           results in build errors.
      
        This has been sitting in linux-next for a few days and has survived
        automated testing by Imagination's test farm. No known regressions
        pending except a number of issues that crept up due to lots of people
