      [PATCH] fix CONFIG_IDEDISK_STROKE support in ide-disk.c · 78808d51
      Bartlomiej Zolnierkiewicz authored
      Original patch from Erik Andersen <andersen@codepoet.org>:
      - fix CONFIG_IDEDISK_STROKE by adding proper detection of HPA feature set
        and removing IDE_STROKE_LIMIT
      - remove irrelevant idedisk_supports_host_protected_area()
      - make the HPA detection actually display useful information
      
      I've reworked it a bit:
      - detect HPA before calculating drive's geometry
      - move HPA detection outside init_idedisk_capacity()
        to idedisk_check_hpa_lba28() and idedisk_check_hpa_lba48()
      - use sectors_to_MB()
      - respect 80-column limit

      [PATCH] init_idedisk_capacity() cleanup() · c98a3356
      Bartlomiej Zolnierkiewicz authored
      - no need to zero drive->capacity48 and drive->select.b.lba
      - don't call idedisk_read_native_max_address_ext() twice
        if drive uses LBA-48 and CONFIG_IDEDISK_STROKE is defined
      - remove uneccessary setup of drive->capacity48/cyl/select.b.lba
        if drive uses LBA-48, maximum virtual LBA address needs to be set
        and CONFIG_IDEDISK_STROKE is defined
      - set drive->cyl only once if drive uses LBA-48
      - don't call idedisk_read_native_max_address() if drive uses LBA-48
        and don't call it twice if CONFIG_IDEDISK_STROKE is defined
      - don't check for Host Protected Area if drive uses CHS addressing
        (such combination is not supported by a driver)
      - remove duplicated code (at the end of the function) that is never executed

      Bartlomiej Zolnierkiewicz authored
      From Benjamin Herrenschmidt <benh@kernel.crashing.org>.
      
      - avoid device list corruption and scheduling at interrupt time

      [PATCH] scsi_ioctl reference counting · fc8183c1
      Jens Axboe authored
      Now that we properly track queue references, that showed a bug in
      scsi_ioctl.c, where it was dropping queues that it had never properly
      gotten in the first place.

      [PATCH] Proper block queue reference counting · ace416a3
      Jens Axboe authored
      To be able to properly be able to keep references to block queues,
      we make blk_init_queue() return the queue that it initialized, and
      let it be independently allocated and then cleaned up on the last
      reference.
      
      I have grepped high and low, and there really shouldn't be any broken
      uses of blk_init_queue() in the kernel drivers left.  The added bonus
      being blk_init_queue() error checking is explicit now, most of the
      drivers were broken in this regard (even IDE/SCSI).
      
      No drivers have embedded request queue structures. Drivers that don't
      use blk_init_queue() but blk_queue_make_request(), should allocate the
      queue with blk_alloc_queue(gfp_mask). I've converted all of them to do
      that, too. They can call blk_cleanup_queue() now too, using the define
      blk_put_queue() is probably cleaner though.

      [PATCH] remove PF_READAHEAD · 7ec6fb01
      Andrew Morton authored
      The problem with PF_READAHEAD is that if someone does a non-GFP_ATOMIC memory
      allocation we can enter page reclaim and then call writepage, while
      PF_READAHEAD is set.  The block layer then drops writes or the wrong reads on
      the floor.  It can cause data loss.
      
      A fix is complex (well, intrusive).  Given that the readahead code is now
      skipping the entire readahead attempt if the queue is congested, the setting
      of PF_READAHEAD probably is not doing anything useful anyway, so simply
      remove it.

      [PATCH] Athlon Machine Check fix · a9c7b26b
      Dave Jones authored
      There seemed to be increase in Athlon users reporting MCEs in 2.6 that
      they never saw in 2.4 and I didn't buy the "2.6 pushes hardware harder"
      for a second given folks are running 2.4+preempt+O(1) etc patchkits
      without problems.
      
      So I did a mini-audit of the mcheck code.
      
      How embarressing. Another fix that went into 2.4 that never made
      it forward. Once I'm done with various Red Hat administrivia
      I'll see if I can devote some time to going through the changesets
      mailing list. I wonder just how many other really stupid bugs
      like this got fixed and not brought forward.

      [PCMCIA] Disable IRQ steering and don't change the IRQ MUX register. · 4c698cc5
      Russell King authored
      The IRQ steering code operates too early at present, and actually
      prevents us detecting ISA interrupts.
      
      We should not touch the IRQ MUX register on TI bridges - only the
      machine itself knows the right value for this.  The kernel doesn't
      have the knowledge to know what function the cardbus controllers
      multi-function pins have been assigned by the hardware manufacturer.

      [NET] X.25 async net_device fixup · aa2b4427
      Stephen Hemminger authored
      Convert X.25 async driver to have dynamic net_device's.
      This driver is a lot like SLIP so the code changes were similar.  
              - Added similar locking to SLIP
              - replaced code that snooped for MTU changes with the
                net_device change mtu callback.
              - cleaned up the statistics by using the net_device_stats structure.
      
      Patch is against 2.6.0-test2.
      
      Not sure if anyone ever uses this.  I tested by bringing up an x.25 async
      line using a modified version of slattach.

      [NET] Fix X.25 use after free. · ee1dc142
      Stephen Hemminger authored
      The conversion from cli/sti to locking in X.25 must not have been tested
      on a real SMP with memory debugging enabled.  It OOPS right away if
      I do:
              modprobe x25; ifconfig -a
      
      The problem is that it dereferences the socket after it has already been
      freed.  The fix for this is to make the call to sock_put, later in
      x25_destroy_socket do the free.  Also, need a go to avoid references
      in x25_release.

      [NET] Fix use after free in AX.25 · ca8c5e0e
      Stephen Hemminger authored
      This patch is against 2.6.0-test2.  The problem is that the ax25_destroy_socket
      function frees the socket buffer, but then ax25_release dereferences this causing
      an OOPS.  To reproduce:
              modprobe ax25; ifconfig -a
      
      Replaced sk_free with sock_put which will free if this is the last reference.

      [NET] Dynamically allocate net_device structures for ROSE · 6ae0b08d
      Stephen Hemminger authored
      This patch changes the ROSE protocol to allocate an array of pointers and each network device
      separately.  This sets up later change where network_device object's are released on last use
      which may be after the module is unloaded.
      
      The patch is against 2.6.0-test2 (though this code hasn't changed in a long time).
      
      
      Allocation is done via alloc_netdev so the dev->priv area is already reserved and
      doesn't need to be allocated separately.
