      Commit the manual part of the input layer merge. · 3c803e8e
      Linus Torvalds 提交于
      git did actually warn me about the fact that I hadn't actually done an
      "update-cache" on these two files, but the warning was at the bottom of
      a list of all the files that _did_ change in the merge, so I never
      noticed.  My bad.

      [PATCH] Cleanup patch for process freezing · 3e1d1d28
      Christoph Lameter 提交于
      1. Establish a simple API for process freezing defined in linux/include/sched.h:
      
         frozen(process)		Check for frozen process
         freezing(process)		Check if a process is being frozen
         freeze(process)		Tell a process to freeze (go to refrigerator)
         thaw_process(process)	Restart process
         frozen_process(process)	Process is frozen now
      
      2. Remove all references to PF_FREEZE and PF_FROZEN from all
         kernel sources except sched.h
      
      3. Fix numerous locations where try_to_freeze is manually done by a driver
      
      4. Remove the argument that is no longer necessary from two function calls.
      
      5. Some whitespace cleanup
      
      6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
         cleared before setting PF_FROZEN, recalc_sigpending does not check
         PF_FROZEN).
      
      This patch does not address the problem of freeze_processes() violating the rule
      that a task may only modify its own flags by setting PF_FREEZE. This is not clean
      in an SMP environment. freeze(process) is therefore not SMP safe!

      [PATCH] RCU: clean up a few remaining synchronize_kernel() calls · b2b18660
      Paul E. McKenney 提交于
      2.6.12-rc6-mm1 has a few remaining synchronize_kernel()s, some (but not
      all) in comments.  This patch changes these synchronize_kernel() calls (and
      comments) to synchronize_rcu() or synchronize_sched() as follows:
      
      - arch/x86_64/kernel/mce.c mce_read(): change to synchronize_sched() to
        handle races with machine-check exceptions (synchronize_rcu() would not cut
        it given RCU implementations intended for hardcore realtime use.
      
      - drivers/input/serio/i8042.c i8042_stop(): change to synchronize_sched() to
        handle races with i8042_interrupt() interrupt handler.  Again,
        synchronize_rcu() would not cut it given RCU implementations intended for
        hardcore realtime use.
      
      - include/*/kdebug.h comments: change to synchronize_sched() to handle races
        with NMIs.  As before, synchronize_rcu() would not cut it...
      
      - include/linux/list.h comment: change to synchronize_rcu(), since this
        comment is for list_del_rcu().
      
      - security/keys/key.c unregister_key_type(): change to synchronize_rcu(),
        since this is interacting with RCU read side.
      
      - security/keys/process_keys.c install_session_keyring(): change to
        synchronize_rcu(), since this is interacting with RCU read side.

      [PATCH] smp_processor_id() cleanup · 39c715b7
      Ingo Molnar 提交于
      This patch implements a number of smp_processor_id() cleanup ideas that
      Arjan van de Ven and I came up with.
      
      The previous __smp_processor_id/_smp_processor_id/smp_processor_id API
      spaghetti was hard to follow both on the implementational and on the
      usage side.
      
      Some of the complexity arose from picking wrong names, some of the
      complexity comes from the fact that not all architectures defined
      __smp_processor_id.
      
      In the new code, there are two externally visible symbols:
      
       - smp_processor_id(): debug variant.
      
       - raw_smp_processor_id(): nondebug variant. Replaces all existing
         uses of _smp_processor_id() and __smp_processor_id(). Defined
         by every SMP architecture in include/asm-*/smp.h.
      
      There is one new internal symbol, dependent on DEBUG_PREEMPT:
      
       - debug_smp_processor_id(): internal debug variant, mapped to
                                   smp_processor_id().
      
      Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new
      lib/smp_processor_id.c file.  All related comments got updated and/or
      clarified.
      
      I have build/boot tested the following 8 .config combinations on x86:
      
       {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}
      
      I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT.  (Other
      architectures are untested, but should work just fine.)
