      [PATCH] 2.5.25 remove global semaphore_lock spin lock. · 72785ef7
      Bob Miller authored
      Replace the global semaphore_lock with the spinlock embedded in
      the wait_queue_head_t.  None of the data protected by semaphore_lock
      is global and there is no need to restrict the system to only allow
      one semaphore to be dealt with at a time.
      
      This removes 2 lock round trips from __down() and __down_interruptible().
      It also reduces the number of cache lines touched by 1 (the cache line
      with seamphore_lock).

      [PATCH] bttv driver update · effdd2b7
      Gerd Knorr authored
      This patch updates the bttv driver.  Changes:
      
       * moved much code to the generic video-buf.c helper module
         (bttv-driver.c, bttv-vbi.c, videobuf.c).
       * a number of changes in the card list and the card-specific code
         (bttv-cards.c).
       * misc small fixes here and there.

      [PATCH] video4linux i2c modules · 6e278fa0
      Gerd Knorr authored
      This patch fixes/improves the TDA8425 support in tvaudio.c.
      It also makes the tvmixer and tvaudio modules look for i2c hardware on
      riva cards (the rivatv project needs this).

      [PATCH] type typo in do_softirq · 551d9631
      Robert Love authored
      kernel/softirq.c :: do_softirq() has a typo in the type of the `cpu'
      value.  I incorrectly set it to `unsigned long' in a previous patch...
      this is a CPU value not a bitmask and is thus an `int'.

      Robert Love authored
      The attached patch makes use of the new list_move_tail macro in 2.5 as
      needed in sched.c, replacing a list_del and list_add_tail combo with the
      optimized list_move_tail.

      [PATCH] direct-to-BIO for O_DIRECT · 42ec8bc1
      Andrew Morton authored
      Here's a patch which converts O_DIRECT to go direct-to-BIO, bypassing
      the kiovec layer.  It's followed by a patch which converts the raw
      driver to use the O_DIRECT engine.
      
      CPU utilisation is about the same as the kiovec-based implementation.
      Read and write bandwidth are the same too, for 128k chunks.   But with
      one megabyte chunks, this implementation is 20% faster at writing.
      
      I assume this is because the kiobuf-based implementation has to stop
      and wait for each 128k chunk, whereas this code streams the entire
      request, regardless of its size.
      
      This is with a single (oldish) scsi disk on aic7xxx.  I'd expect the
      margin to widen on higher-end hardware which likes to have more
      requests in flight.
      
      Question is: what do we want to do with this sucker?  These are the
      remaining users of kiovecs:
      
      	drivers/md/lvm-snap.c
      	drivers/media/video/video-buf.c
      	drivers/mtd/devices/blkmtd.c
      	drivers/scsi/sg.c
      
      the video and mtd drivers seems to be fairly easy to de-kiobufize.
      I'm aware of one proprietary driver which uses kiobufs.  XFS uses
      kiobufs a little bit - just to map the pages.
      
      So with a bit of effort and maintainer-irritation, we can extract
      the kiobuf layer from the kernel.

      [PATCH] IDE 98 · 2dbd1502
      Martin Dalecki authored
      Synchronize with 2.5.25.
      
      Incorporate IDE-94, as well as 95, 96, 97 and 98-pre as announced by Bartek and
      unfortunately still not included in 2.5.25, which makes admittedly things
      still fall appart:
      
      Missing changelog for 98-pre by Bartlomiej Zolnierkiewicz (BTW.  Handling
      Unicode should be essential at least to make proper crediting of many many
      peoples possible!) follows here:
      
       - add missing channel->lock unlocking/locking and fix some comments
         in ide_timer_expiry()
      
       - allow PCI drivers to disable autodma in ->init_dma()
         (bug introduced in IDE 97, affects sl82c105.c only)
      
         noticed by Russell King
      
       - alim15x3.c, if revision is <= 0x20 disable autodma
      
       - remove unneeded checks (drive.dn > 3) from pdc202xx.c and sis5513.c
      
       - use block layer wrappers
      
      And my additions follow:
      
       - Fix TCQ code. Patch based on work by Alexander Atanasov.
      
       - Use the FreeBSD derived request handler return values:
      
      	ATA_OP_FINISHED
      	ATA_OP_CONTINUES
      	ATA_OP_RELEASED
      	ATA_OP_READY	/* for status ready reporting during poll */
      
       - PMAC compilation fix by Paul Mackerras.
      
       - Simplify the ata_status_poll function significantly.
      
       - Fix logic used to prevent drive IRQ assertion from drive on channels sharing
         our interrupt.
      
      NOTE: We will move it later to the time where a request is really finished
      soon.
      
       - Don't use ata_busy_poll() use ata_status_poll() instead. This increases code
         unification.
      
      NOTE: We should maybe invent some way to prevent the error recovery path to be
      taken at all. In esp to prevent ata_error from trying to reissue commands.

      [PATCH] IEEE1394 updates · ca3dd564
      Ben Collins authored
      This is against 2.5.25. Lots of fixes. Brings things inline with 2.5.25.
      Probably makes the subsystem actually work now (well, it will work, but
      I bet without it, it doesn't). Merged in changes from the current 2.5.x
      source.

      NTFS: 2.0.20 - Support non-resident directory index bitmaps, fix page leak in readdir. · a5ea1066
      Anton Altaparmakov authored
      - Move the directory index bitmap to use an attribute inode instead of
        having special fields for it inside the ntfs inode structure. This
        means that the index bitmaps now use the page cache for i/o, too,
        and also as a side effect we get support for non-resident index
        bitmaps for free.
      - Simplify/cleanup error handling in fs/ntfs/dir.c::ntfs_readdir() and
        fix a page leak that manifested itself in some cases.
      - Add fs/ntfs/inode.c::ntfs_put_inode(), which we need to release the
        index bitmap inode on the final iput().

      NTFS: 2.0.19 - Fix race condition, improvements, and optimizations in i/o interface. · 1138bf4c
      Anton Altaparmakov authored
      - Apply block optimization added to fs/ntfs/aops.c::ntfs_read_block()
        to fs/ntfs/compress.c::ntfs_file_read_compressed_block() as well.
      - Drop the "file" from ntfs_file_read_compressed_block().
      - Rename fs/ntfs/aops.c::ntfs_enb_buffer_read_async() to
        ntfs_end_buffer_async_read() (more like the fs/buffer.c counterpart).
      - Update ntfs_end_buffer_async_read() with the improved logic from
        its updated counterpart fs/buffer.c::end_buffer_async_read(). Apply
        further logic improvements to better determine when we set PageError.
      - Update submission of buffers in fs/ntfs/aops.c::ntfs_read_block() to
        check for the buffers being uptodate first in line with the updated
        fs/buffer.c::block_read_full_page(). This plugs a small race
        condition.
