      [PATCH] kill wall_jiffies · 8ef38609
      Atsushi Nemoto 提交于
      With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
      So we can kill wall_jiffies completely.
      
      This is just a cleanup and logically should not change any real behavior
      except for one thing: RTC updating code in (old) ppc and xtensa use a
      condition "jiffies - wall_jiffies == 1".  This condition is never met so I
      suppose it is just a bug.  I just remove that condition only instead of
      kill the whole "if" block.

      [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) · 3171a030
      Atsushi Nemoto 提交于
      Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
      timer interrupt handler with this change.
      
      Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
      callers of do_timer() should know how many ticks to update.  Passing ticks
      get rid of this redundant calculation.  Also there are another redundancy
      pointed out by Martin Schwidefsky.
      
      This cleanup make a barrier added by
      5aee405c needless.  So this patch removes
      it.
      
      As a bonus, this cleanup make wall_jiffies can be removed easily, since now
      wall_jiffies is always synced with jiffies.  (This patch does not really
      remove wall_jiffies.  It would be another cleanup patch)

      [PATCH] genirq: rename desc->handler to desc->chip · d1bef4ed
      Ingo Molnar 提交于
      This patch-queue improves the generic IRQ layer to be truly generic, by adding
      various abstractions and features to it, without impacting existing
      functionality.
      
      While the queue can be best described as "fix and improve everything in the
      generic IRQ layer that we could think of", and thus it consists of many
      smaller features and lots of cleanups, the one feature that stands out most is
      the new 'irq chip' abstraction.
      
      The irq-chip abstraction is about describing and coding and IRQ controller
      driver by mapping its raw hardware capabilities [and quirks, if needed] in a
      straightforward way, without having to think about "IRQ flow"
      (level/edge/etc.) type of details.
      
      This stands in contrast with the current 'irq-type' model of genirq
      architectures, which 'mixes' raw hardware capabilities with 'flow' details.
      The patchset supports both types of irq controller designs at once, and
      converts i386 and x86_64 to the new irq-chip design.
      
      As a bonus side-effect of the irq-chip approach, chained interrupt controllers
      (master/slave PIC constructs, etc.) are now supported by design as well.
      
      The end result of this patchset intends to be simpler architecture-level code
      and more consolidation between architectures.
      
      We reused many bits of code and many concepts from Russell King's ARM IRQ
      layer, the merging of which was one of the motivations for this patchset.
      
      This patch:
      
      rename desc->handler to desc->chip.
      
      Originally i did not want to do this, because it's a big patch.  But having
      both "desc->handler", "desc->handle_irq" and "action->handler" caused a
      large degree of confusion and made the code appear alot less clean than it
      truly is.
      
      I have also attempted a dual approach as well by introducing a
      desc->chip alias - but that just wasnt robust enough and broke
      frequently.
      
      So lets get over with this quickly.  The conversion was done automatically
      via scripts and converts all the code in the kernel.
      
      This renaming patch is the first one amongst the patches, so that the
      remaining patches can stay flexible and can be merged and split up
      without having some big monolithic patch act as a merge barrier.

      [PATCH] unify PFN_* macros · 22a9835c
      Dave Hansen 提交于
      Just about every architecture defines some macros to do operations on pfns.
       They're all virtually identical.  This patch consolidates all of them.
      
      One minor glitch is that at least i386 uses them in a very skeletal header
      file.  To keep away from #include dependency hell, I stuck the new
      definitions in a new, isolated header.
      
      Of all of the implementations, sh64 is the only one that varied by a bit.
      It used some masks to ensure that any sign-extension got ripped away before
      the arithmetic is done.  This has been posted to that sh64 maintainers and
      the development list.
      
      Compiles on x86, x86_64, ia64 and ppc64.

      [PATCH] more for_each_cpu() conversions · 394e3902
      Andrew Morton 提交于
      When we stop allocating percpu memory for not-possible CPUs we must not touch
      the percpu data for not-possible CPUs at all.  The correct way of doing this
      is to test cpu_possible() or to use for_each_cpu().
      
      This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
      few instances of this bug, if any.  But the patch converts lots of open-coded
      test to use the preferred helper macros.

      [PATCH] sched: disable preempt in idle tasks · 5bfb5d69
      Nick Piggin 提交于
      Run idle threads with preempt disabled.
      
      Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
      How did it ever work before?
      
      Might fix the CPU hotplugging hang which Nigel Cunningham noted.
      
      We think the bug hits if the idle thread is preempted after checking
      need_resched() and before going to sleep, then the CPU offlined.
      
      After calling stop_machine_run, the CPU eventually returns from preemption and
      into the idle thread and goes to sleep.  The CPU will continue executing
      previous idle and have no chance to call play_dead.
      
      By disabling preemption until we are ready to explicitly schedule, this bug is
      fixed and the idle threads generally become more robust.

      [PATCH] fix missing includes · 4e57b681
      Tim Schmielau 提交于
      I recently picked up my older work to remove unnecessary #includes of
      sched.h, starting from a patch by Dave Jones to not include sched.h
      from module.h. This reduces the number of indirect includes of sched.h
      by ~300. Another ~400 pointless direct includes can be removed after
      this disentangling (patch to follow later).
      However, quite a few indirect includes need to be fixed up for this.
      
      In order to feed the patches through -mm with as little disturbance as
      possible, I've split out the fixes I accumulated up to now (complete for
      i386 and x86_64, more archs to follow later) and post them before the real
      patch.  This way this large part of the patch is kept simple with only
      adding #includes, and all hunks are independent of each other.  So if any
      hunk rejects or gets in the way of other patches, just drop it.  My scripts
      will pick it up again in the next round.
