      [PATCH] v4l: #1 - video-buf update · 868bec44
      Andrew Morton authored
      From: Gerd Knorr <kraxel@bytesex.org>
      
      This minor patch updates the video-buf module.  It just adds a export
      for the videobuf_next_field function and adds some debug printk's.

      [PATCH] Fix for latent bug in vmtruncate() · 98063ca7
      Andrew Morton authored
      From: "Paul E. McKenney" <paulmck@us.ibm.com>
      
      The vmtruncate() function shifts down by PAGE_CACHE_SHIFT, then calls
      vmtruncate_list(), which deals in terms of PAGE_SHIFT instead.  Currently,
      no harm done, since PAGE_CACHE_SHIFT and PAGE_SHIFT are identical.  Some
      day they might not be, hence this patch.
      
      I also took the liberty of modifying a hand-coded "if" that seems to
      optimize for files that are not mapped to instead use unlikely().

      [PATCH] fix CONFIG_APM=m · e432a562
      Andrew Morton authored
      From: mikpe@csd.uu.se
      
      Here is a patch to fix CONFIG_APM=m in 2.5.69-bk11.  My patch to have APM
      restore the systenter MSRs failed to handle the modular case, which fails
      with unresolved symbols.
      
      Since suspend.o is used from both APM (module or built-in) and ACPI sleep
      (built-in), I made suspend.o built-in and dependent on CONFIG_PM.

      [PATCH] reiserfs: reiserfs_file_write implementation · afd64673
      Andrew Morton authored
      From: Oleg Drokin <green@namesys.com>
      
      With the current 'one block at a time' algorithm, writes past the end of a
      file are slow because each new file block is separately added into the tree
      causing shifting of other items which is CPU expensive.
      
      With this new implementation if you write into file with big enough chunks,
      it uses half as much CPU.  Also this version is more SMP friendly than the
      current one.
      
      There are some known-bad applications that break with this patch (ie.  start
      to work very slow or even hang).
      
      This is because the filesystem returns a large value in the stat.st_blocksize
      hint (128k instead of 4k).  This tickles a small number of application bugs.
      One is KDE's kmail 3.04 (fixed by upgrading to 3.1+) and the other is
      sleepycat's database from before 1997.
      
      If you hit a slowdown problem that you believe is related to the increased
      "recommended i/o size" value, try to mount your fs with nolargeio=1 mount
      option (remount should work too).
      
      This patch exports block_commit_write(), generic_osync_inode() and
      remove_suid() to modules.

      [PATCH] reiserfs: allow multiple block insertion into the tree · a61638bc
      Andrew Morton authored
      I've had these reiserfs patches in -mm for many months.  We've been
      undecided because they trigger bugs in a couple of apps.  But those apps
      are now fixed, so it's best to get these speedups in.
      
      
      From: Oleg Drokin <green@namesys.com>
      
      This patch allows insertion of more than one "indirect" block pointer into
      the tree in reiserfs.  (with all the necessary balancing code changes).
      The first user of that feature is hole-creation code that is now ~1000
      times more cpu-efficient for the case of large holes.

      [PATCH] 3c59x irqreturn fix · 130a14f4
      Andrew Morton authored
      Apparently boomerang_interrupt() is generating lots of "nobody cared"
      warnings - one per packet it seems.  Frankly, I don't have a clue why.
      
      These are ancient cards and the driver is otherwise stable, so just
      change it to return IRQ_HANDLED and move on...

      [PATCH] large-dma_addr_t-PAE-only.patch · 03feb9db
      Andrew Morton authored
      From: William Lee Irwin III <wli@holomorphy.com>
      
      I was just looking over this and noticed 2.4.x makes u64 dma_addr_t
      conditional on CONFIG_HIGHMEM64G where 2.5.x uses CONFIG_HIGHMEM.  It's
      clearly not necessary on CONFIG_HIGHMEM4G, hence this obvious patch.

      [PATCH] ia32 subarch circular dependency fix · 80d21417
      Andrew Morton authored
      From: john stultz <johnstul@us.ibm.com>
      
      This patch fixes a circular dependency (a function in mach_apic.h requires
      hard_smp_processor_id() and hard_smp_processor_id() requires macros from
      mach_apic.h) that has been in the subarch code for a bit, but was hacked
      around with some #ifdefs.
      
      With the inclusion of the generic-subarch the hack was dropped and bigsmp
      and summit promptly broke.  So this makes things compile again.
