         - 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.

      x86: MCE: Add raw_lock conversion again · ed5c41d3
      Thomas Gleixner 提交于
      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.

      cxgb4 : Disable recursive mailbox commands when enabling vi · 30f00847
      Anish Bhatt 提交于
      Enabling a Virtual Interface can result in an interrupt during the processing
       of the VI Enable command and, in some paths, result in an attempt to issue
      another command in the interrupt context, eventually crashing the system. Thus,
       we disable interrupts during the course of the VI Enable command and ensure
      enable doesn't sleep.

      amd-xgbe: Perform phy connect/disconnect at dev open/stop · 88131a81
      Lendacky, Thomas 提交于
      A change added to the mdiobus/phy api added a module_get/module_put
      during phy connect/disconnect processing. Currently, the driver
      performs a phy connect during module probe and a phy disconnect during
      module remove. With the addition of the module_get during phy connect
      the amd-xgbe module use count is incremented and can no longer be
      unloaded.
      
      Move the phy connect/disconnect from the driver probe/remove functions
      to the net_device_ops ndo_open/ndo_stop functions.  This allows the
      module use count to be decremented when the device(s) are brought down
      and allows the module to be unloaded.
