      [PATCH] Missing end tags in kernel-locking kerneldoc · ac987996

      The new-and-improved kernel-locking kerneldoc seems to be missing some end
      tags which causes 'make foodocs' to die.  I'm not sure if it's because of
      my not-bleeding-edge docbook utils or if it's a genuine error.  Since most
      ending tags are present I tend to think it's an error.

      [PATCH] Use for_each_cpu() Where It's Meant To Be · 012061cc

      [PATCH] Make for_each_cpu() Iterator More Friendly · 90c7f719
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      Anton: breaks PPC64, as it needs cpu_possible_mask, but fix is already
      in Ameslab tree.
      
      The for_each_cpu() and for_each_online_cpu() iterators take a mask, and
      noone uses them that way (except for arch/i386/mach-voyager, which uses
      for_each_cpu(cpu_online_mask).  Make them more usable iterators, by
      dropping the "mask" arg.
      
      This requires that archs provide a cpu_possible_mask: most do, but PPC64
      doesn't, so it is broken by this patch.  The other archs use a #define to
      define it in asm/smp.h.
      
      Most places doing loops over cpus testing for cpu_online() should use
      for_each_cpu: it is synonymous at the moment, but with the CPU hotplug
      patch the difference becomes important.
      
      Followup patches will convert users.

      [PATCH] O21 for interactivity 2.6.0 · 8c6f4906
      Andrew Morton authored
      From: Con Kolivas <kernel@kolivas.org>
      
      A non-critical corner case has come up for interactivity that I believe needs 
      to be addressed. It is only extensive testing and examination that revealed
      this, as this interactivity work is in maintenance mode.
      
      Description:
      
        It is possible for a highly interactive task (like X) to cause large
        latencies in tasks that are less 'niced' (eg negative nice number
        compared to X which should normally run at nice 0) if they are fully
        cpu bound.  This occurs due to expiration of the cpu bound tasks.
      
        This patch addresses this by not reinserting interactive tasks into
        the active array if there is a better static priority task running but
        has been placed on the expired array.  This causes a substantial
        reduction in the maximum scheduling latency a task with a less nice
        value can have. 
      
        This also has the positive side effect of maintaining better cpu%
        proportions for tasks of different nice levels.
      
      Testers will only be able to discern a difference with highly cpu bound tasks 
      of normal scheduling policy at different nice levels. Test cases are doing 
      something cpu intensive relatively -niced in the presence of an interactive
      load (eg capturing and encoding video at nice -10 while using X nice 0, or 
      something nice 0 vs nice +10) and so on. Because of the crossover of 10 
      'nice' levels of dynamic priorities between interactive and cpu bound tasks
      this patch will have a more noticable effect as the nice difference is
      greater, especially 11 or more.

      [PATCH] kill_fasync speedup · f6ef9d5b
      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      fasync_helper and kill_fasync are helpers for managing F_SETFL fcntl 
      calls that change FASYNC and sending the necessary signals. The locking 
      uses one global rwlock that's acquired for read in all kill_fasync
      calls, and that causes cache line trashing. This is not necessary: if
      the fasync list is empty, then there is no need to acquire the rwlock.
      Tests with reaim on a 4-way pIII on STP showed an 80% reduction of the
      time within kill_fasync.

      Replace the various CardServices() calls w/ their pcmcia_* function.  The

      [PATCH] make try_to_free_pages walk zonelist · d5d4042d
      Andrew Morton authored
      From: Rik van Riel <riel@surriel.com>
      
      In 2.6.0 both __alloc_pages() and the corresponding wakeup_kswapd()s walk
      all zones in the zone list, possibly spanning multiple nodes in a low numa
      factor system like AMD64.
      
      Also, if lower_zone_protection is set in /proc, then it may be possible
      that kswapd never cleans out data in zones further down the zonelist and
      try_to_free_pages needs to do that.
      
      However, in 2.6.0 try_to_free_pages() only frees pages in the pgdat the
      first zone in the zonelist belongs to.
      
      This is probably the wrong behaviour, since both the page allocator and the
      kswapd wakeup free things from all zones on the zonelist.  The following
      patch makes try_to_free_pages() consistent with the allocator, by passing
      the zonelist as an argument and freeing pages from all zones in the list.
      
      I do not have any numa systems myself, so I have only tested it on my own
      little smp box.  Testing on NUMA systems may be useful, though the patch
      really only should have an impact in those rare cases where kswapd can't
      keep up with allocations...
      
      As a side effect, the patch shrinks the kernel by 2 lines and replaces some
      subtle magic by a simpler array walk.

      [PATCH] Make ppp_async callable from hard interrupt · 2996d8de
      Andrew Morton authored
      From: Paul Mackerras <paulus@samba.org>
      
      Since there are serial drivers (particularly the USB serial driver) that
      call the line discipline receive_buf and write_wakeup routines at hard
      interrupt level, I have changed the ppp_async code to cope with that.  It
      now uses a tasklet so that it calls the generic PPP code at soft interrupt
      level even if its receive_buf and write_wakeup entries are called at hard
      interrupt level.
      
      This patch has been lightly tested here with a keyspan USB serial adaptor
      and also with the built-in modem on my tibook, which uses the pmac_zilog
      driver (which hooks into the drivers/serial infrastructure).
