      [PATCH] show_free_areas() cleanup · c1ab3459
      Andrew Morton authored
      Cleanup to show_free_areas() from Bill Irwin:
      
      show_free_areas() and show_free_areas_core() is a mess.
      (1) it uses a bizarre and ugly form of list iteration to walk buddy lists
              use standard list functions instead
      (2) it prints the same information repeatedly once per-node
              rationalize the braindamaged iteration logic
      (3) show_free_areas_node() is useless and not called anywhere
              remove it entirely
      (4) show_free_areas() itself just calls show_free_areas_core()
              remove show_free_areas_core() and do the stuff directly
      (5) SWAP_CACHE_INFO is always #defined, remove it
      (6) INC_CACHE_INFO() doesn't use the do { } while (0) construct
      
      This patch also includes Matthew Dobson's patch which removes
      mm/numa.c:node_lock.  The consensus is that it doesn't do anything now
      that show_free_areas_node() isn't there.

      [PATCH] use a slab cache for pte_chains · cbb6e8ec
      Andrew Morton authored
      Patch from Bill Irwin.
      
      It removes the custom pte_chain allocator in mm/rmap.c and replaces it
      with a slab cache.
      
      "This patch
       (1) eliminates the pte_chain_freelist_lock and all contention on it
       (2) gives the VM the ability to recover unused pte_chain pages
      
       Anton Blanchard has reported (1) from prior incarnations of this patch.
       Craig Kulesa has reported (2) in combination with slab-on-LRU patches.
      
       I've left OOM detection out of this patch entirely as upcoming patches
       will do real OOM handling for pte_chains and all the code changed anyway."

      [PATCH] misc fixes · 1a40868e
      Andrew Morton authored
      There are a few VM-related patches in this series.  Mainly fixes;
      feature work is on hold.
      
      We have some fairly serious locking contention problems with the reverse
      mapping's pte_chains.  Until we have a clear way out of that I believe
      that it is best to not merge code which has a lot of rmap dependency.
      
      It is apparent that these problems will not be solved by tweaking -
      some redesign is needed.  In the 2.5 timeframe the only practical
      solution appears to be page table sharing, based on Daniel's February
      work.  Daniel and Dave McCracken are working that.
      
      Some bits and pieces here:
      
      - list_splice() has an open-coded list_empty() in it.  Use
        list_empty() instead.
      
      - in shrink_cache() we have a local `nr_pages' which shadows another
        local.  Rename the inner one.  (Nikita Danilov)
      
      - Add a BUG() on a can't-happen code path in page_remove_rmap().
      
      - Tighten up the bug checks in the BH completion handlers - if the
        buffer is still under IO then it must be locked, because we unlock it
        inside the page_uptodate_lock.

      [PATCH] APM fixes, 2.5.29 · 06ba030a
      Ingo Molnar authored
      the attached patch fixes two things:
      
       - a TLS related bug noticed by Arjan van de Ven: apm_init() should set up
         all CPU's gdt entries - just in case some code happens to call in the
         APM BIOS on the wrong CPU. This should also handle the case when some
         APM code gets triggered (by suspend or power button or something).

      Muli Ben-Yehuda authored
      This patch (1/2) brings the sound/oss/trident.c driver up to date with
      the driver in the 2.4-ac tree. It fixes the following bugs:
      
      * fix wrong cast in suspend/resume (Eric Lemar via Ian Soboroff)
      
      * fix bug where we would free with free_pages() memory allocated via
      pci_alloc_consistent().
      
      * add a missing unlock on an error path.
      
      * rewrite the code to read/write registers of audio codecs for Ali5451
      (Lei Hu)
      
      It also does various cleanups so that the code conforms to
      Documentation/CodingStyle and is nicer to work with.

      We use the pci host lock so that we lock config space portably while

      ensure that we lock at a portable layer. Also add the 2.4.19 fixes for
      avoiding wrong probes, and the fix noted on the list.

      [PATCH] partition fix · cab49a97
      Andries E. Brouwer authored
      The patch below does two things:
      
      (i) fixes a small bug in the new partition code
      This is the final chunk s/n/slot/. I'll refrain from giving a vi script.
      This is uncontroversial.
      
      (ii) removes ancient garbage concerning disk managers
      This may well be controversial.
      
      (Long ago, when disks became larger than 500 MB, lots of tricks were
      invented to keep DOS happy. Both hardware tricks and software tricks.
      One of the software tricks was the invention of boot managers.
      There have been many of those. The Linux kernel has had support
      for two of them: OnTrack Disk Manager and EZdrive.
      More precisely: there have been many versions of both OnTrack Disk Manager
      and EZdrive, and the kernel had support for a few of these versions.
      
      I think the time has come to remove the automatic support - every now
      and then it bites some innocent user, and the support is not really
      needed any longer, and the support is for outdated versions of these
      boot managers.
      
      No doubt it will turn out that users still exist that use some form
      of this stuff, but I would prefer to support them by explicit
      kernel boot parameters, rather than by code that guesses what
      might be the right thing to do.
      
      The patch below just rips out the old stuff. Depending on the screams
      this might provoke I expect to add some boot parameters.)

      [PATCH] fix synchronize_irq() bug · 3f9a1484
      Ingo Molnar authored
      This fixes a synchronize_irq() bug: if the interrupt is freed while an
      IRQ handler is running (irq state is IRQ_INPROGRESS) then
      synchronize_irq() will return early, which is incorrect.
      
      there was another do_IRQ() bug that in fact necessiated the bad code that
      caused the synchronize_irq() bug - we kept the IRQ_INPROGRESS bit set for
      not active interrupt sources - after they happen for the first time. Now
      the only effect this has is on i8259A irq handling - we used to keep these
      irqs disabled after the first 'spurious' interrupt happened.  Now what the
      i8259A code really wants to do IMO is to keep the interrupt disabled if
      there is no handler defined for that interrupt source. The patch adds
      exactly this. I dont remember why this was needed in the first place (irq
      probing? avoidance of interrupt storms?), but with the patch the behavior
      should be equivalent.

      [PATCH] scheduler, migration startup fixes, 2.5.29 · cd4cb274
      Ingo Molnar authored
      the attached patch fixes the scheduler's migration thread startup bug that
      got unearthed by Rusty's recent CPU-startup enhancements.
      
      the fix is to let a startup-helper thread migrate the migration thread,
      instead of the migration thread calling set_cpus_allowed() itself.
      Migrating a not running thread is a simple and robust thing, and needs no
      cooperation from migration threads - thus the catch-22 problem of how to
      migrate the migration threads is solved finally.
      
      the patch is against Rusty's initcall fix/hack which calls
      migration_init() before other CPUs are brought up - this ordering is
      clearly the clean way of doing migration init. [the patch also fixes a UP
      compiliation bug in Rusty's hack.]

      [ARM PATCH] 1179/1: ldm/stm alignement fixups: treat 920T the same as 922T · e861caac
      Guido Barzini authored
       The check in do_alignment_ldmstm for addr and eaddr being the same is #ifdef'd
      out for the ARM922T because they aren't expected to be the same due to the 
      different way the MMU sets addr. The ARM920T is just a 922T with more cache, 
      and should be treated the same. I've checked on a real ARM920T and it does 
      complain loudly every time it fixes up a misaligned ldm/stm unless this 
      patch is applied.
       I suspect that the ARM926 should be treated the same way as well, but I can't
      find any relevant documentation on ARM's web-site, so have left it out.
