      Pull sparc updates from David Miller:
      
       1) Add sparc RAM output to /proc/iomem, from Bob Picco.
      
       2) Allow seeks on /dev/mdesc, from Khalid Aziz.
      
       3) Cleanup sparc64 I/O accessors, from Sam Ravnborg.
      
       4) If update_mmu_cache{,_pmd}() is called with an not-valid mapping, do
          not insert it into the TLB miss hash tables otherwise we'll
          livelock.  Based upon work by Christopher Alexander Tobias Schulze.
      
       5) Fix BREAK detection in sunsab driver when no actual characters are
          pending, from Christopher Alexander Tobias Schulze.
      
       6) Because we have modules --> openfirmware --> vmalloc ordering of
          virtual memory, the lazy VMAP TLB flusher can cons up an invocation
          of flush_tlb_kernel_range() that covers the openfirmware address
          range.  Unfortunately this will flush out the firmware's locked TLB
          mapping which causes all kinds of trouble.  Just split up the flush
          request if this happens, but in the long term the lazy VMAP flusher
          should probably be made a little bit smarter.

       "Highlights:
      
         1) Steady transitioning of the BPF instructure to a generic spot so

         3) Take advantage of hash table in UDP multicast delivery, from David
            Held.
      
         4) Lighten locking, in particular by getting rid of the LRU lists, in
            inet frag handling.  From Florian Westphal.
      
         5) Add support for various RFC6458 control messages in SCTP, from
            Geir Ola Vaagland.
      
         6) Allow to filter bridge forwarding database dumps by device, from

            Brouer.
      
         9) Add support for ipv6 address generation modes, so that userland

        13) Maintain a name assignment type so that userspace can see where a
            network device name came from (enumerated by kernel, assigned
            explicitly by userspace, etc.) From Tom Gundersen.
      
        14) Automatic flow label generation on transmit in ipv6, from Tom
            Herbert.
      
        15) New packet timestamping facilities from Willem de Bruijn, meant to
            assist in measuring latencies going into/out-of the packet
            scheduler, latency from TCP data transmission to ACK, etc"

      Pull timer and time updates from Thomas Gleixner:
       "A rather large update of timers, timekeeping & co
      
         - Core timekeeping code is year-2038 safe now for 32bit machines.
           Now we just need to fix all in kernel users and the gazillion of
           user space interfaces which rely on timespec/timeval :)
      
         - Better cache layout for the timekeeping internal data structures.
      
         - Proper nanosecond based interfaces for in kernel users.
      
         - Tree wide cleanup of code which wants nanoseconds but does hoops
           and loops to convert back and forth from timespecs.  Some of it
           definitely belongs into the ugly code museum.
      
         - Consolidation of the timekeeping interface zoo.
      
         - A fast NMI safe accessor to clock monotonic for tracing.  This is a
           long standing request to support correlated user/kernel space
           traces.  With proper NTP frequency correction it's also suitable
           for correlation of traces accross separate machines.
      
         - Checkpoint/restart support for timerfd.
      
         - A few NOHZ[_FULL] improvements in the [hr]timer code.
      
         - Code move from kernel to kernel/time of all time* related code.
      
         - New clocksource/event drivers from the ARM universe.  I'm really
           impressed that despite an architected timer in the newer chips SoC
           manufacturers insist on inventing new and differently broken SoC
           specific timers.
      
      [ Ed. "Impressed"? I don't think that word means what you think it means ]
      
         - Another round of code move from arch to drivers.  Looks like most
           of the legacy mess in ARM regarding timers is sorted out except for
           a few obnoxious strongholds.
      
         - The usual updates and fixlets all over the place"

      x86: MCE: Add raw_lock conversion again · ed5c41d3
      Thomas Gleixner authored
      Commit ea431643 ("x86/mce: Fix CMCI preemption bugs") breaks RT by
      the completely unrelated conversion of the cmci_discover_lock to a
      regular (non raw) spinlock.  This lock was annotated in commit
      59d958d2 ("locking, x86: mce: Annotate cmci_discover_lock as raw")
      with a proper explanation why.
      
      The argument for converting the lock back to a regular spinlock was:
      
       - it does percpu ops without disabling preemption. Preemption is not
         disabled due to the mistaken use of a raw spinlock.
      
      Which is complete nonsense.  The raw_spinlock is disabling preemption in
      the same way as a regular spinlock.  In mainline spinlock maps to
      raw_spinlock, in RT spinlock becomes a "sleeping" lock.
      
      raw_spinlock has on RT exactly the same semantics as in mainline.  And
      because this lock is taken in non preemptible context it must be raw on
      RT.
      
      Undo the locking brainfart.
