        The "largest" changes are in the mei driver, to resolve some reported

      Linus Torvalds authored
      Pull kgdb fixes from Daniel Thompson:
       "The main change here is a fix for a number of unsafe interactions
        between kdb and the console system. The fixes are specific to kdb
        (pure kgdb debugging does not use the console system at all). On
        systems with an NMI then kdb, if it is enabled, must get messages to
        the user despite potentially running from some "difficult" calling
        contexts. These fixes avoid using the console system where we have
        been provided an alternative (safer) way to interact with the user
        and, if using the console system in unavoidable, use oops_in_progress
        for deadlock avoidance. These fixes also ensure kdb honours the
        console enable flag.
      
        Also included is a fix that wraps kgdb trap handling in an RCU read
        lock to avoids triggering diagnostic warnings. This is a wide lock
        scope but this is OK because kgdb is a stop-the-world debugger. When
        we stop the world we put all the CPUs into holding pens and this
        inhibits RCU update anyway"

      Pull arm64 fixes from Will Deacon:
       "The big fix here is to our vDSO sigreturn trampoline as, after a
        painfully long stint of debugging, it turned out that fixing some of
        our CFI directives in the merge window lit up a bunch of logic in
        libgcc which has been shown to SEGV in some cases during asynchronous
        pthread cancellation.
      
        It looks like we can fix this by extending the directives to restore
        most of the interrupted register state from the sigcontext, but it's
        risky and hard to test so we opted to remove the CFI directives for
        now and rely on the unwinder fallback path like we used to.
