      Pull x86 fixes from Thomas Gleixner:
       "A set of three patches to fix the fallout of the newly added split
        lock detection feature.
        It addressed the case where a KVM guest triggers a split lock #AC and
        KVM reinjects it into the guest which is not prepared to handle it.
        Add proper sanity checks which prevent the unconditional injection
        into the guest and handles the #AC on the host side in the same way as
        user space detections are handled. Depending on the detection mode it
        either warns and disables detection for the task or kills the task if
        the mode is set to fatal"

      Pull time(keeping) updates from Thomas Gleixner:
       - Fix the time_for_children symlink in /proc/$PID/ so it properly
         reflects that it part of the 'time' namespace
       - Add the missing userns limit for the allowed number of time
         namespaces, which was half defined but the actual array member was
         not added. This went unnoticed as the array has an exessive empty
         member at the end but introduced a user visible regression as the
         output was corrupted.
       - Prevent further silent ucount corruption by adding a BUILD_BUG_ON()
         to catch half updated data.

      Pull scheduler fixes/updates from Thomas Gleixner:
       - Deduplicate the average computations in the scheduler core and the
         fair class code.
       - Fix a raise between runtime distribution and assignement which can
         cause exceeding the quota by up to 70%.
       - Prevent negative results in the imbalanace calculation
       - Remove a stale warning in the workqueue code which can be triggered
         since the call site was moved out of preempt disabled code. It's a
         false positive.
       - Deduplicate the print macros for procfs
       - Add the ucmap values to the SCHED_DEBUG procfs output for completness
