      [PATCH] NMI watchdog documentation for x86-64 · d8aceb1c
      Andrew Morton authored
      From: Ville Herva <vherva@niksula.hut.fi>
      
      NMI watchdog is nowadays supported on x86-64, too. The nmi-watchdog.txt
      document doesn't mention this. Here is a patch to add a few words on that.

      [PATCH] fix free_all_bootmem_core for virtual memmap · 767aa962
      Andrew Morton authored
      From: jbarnes@sgi.com (Jesse Barnes)
      
      Currently, free_all_bootmem_core() assumes that the bdata for a given
      node will begin where the node's memory map begins.  This isn't
      necessarily true on machines that use a virtual memory map (e.g. ia64
      discontig machines), so we fix page to point to the first actual page of
      RAM on the node, which _does_ contain the bdata struct.

      [PATCH] might_sleep() checks for x86 usercopy functions · 4bca8b2e
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      This only checks in the non-__ versions, as those are occassionally
      called inside things like kmap_atomic pairs which take a spinlock in
      with highmem. It's all conditional on CONFIG_DEBUG_SPINLOCK_SLEEP
      (which isn't quite the right name) so there's no overhead for normal
      builds.

      [PATCH] ide-cd error handling oops fix · 30c633b8
      Andrew Morton authored
      cdrom_decode_status() can call cdrom_end_request() twice.  The second call

      [PATCH] move_one_page() atomicity fix · 8a8f9d8e
      Andrew Morton authored
      move_one_page() is awkward.  It grabs an atomic_kmap of the source pte
      (because it needs to know if there's really a page there) and then it needs
      to allocate a pte for the dest.  But it cannot allocate the dest pte while
      holding the src's atomic kmap.
      
      So it performs this little dance peeking at pagetables to predict if
      alloc_one_pte_map() might need to perform a pte page allocation.
      
      When I wrote this code I made it conditional on CONFIG_HIGHPTE.  But that was
      bogus: even in the !CONFIG_HIGHPTE case, get_one_pte_map_nested() will run
      atomic_kmap() against the pte page, which disables preemption.
      
      Net effect: with CONFIG_HIGHMEM && !CONFIG_HIGHPTE we can end up performing a
      GFP_KERNEL pte page allocation while preemption is disabled.  It triggers a
      might_sleep() warning and indeed is buggy.
      
      So the patch removes the conditionality: even in the !CONFIG_HIGHPTE case we
      still do the pagetable peek and drop the kmap if necessary.
      
      (Arguably, we shouldn't be performing the atomic_kmap() at all if
      !CONFIG_HIGHPTE: all it does is a pointless preemption disable).
      
      (Arguably, kmap_atomic() should not be disabling preemption if the target
      page is not highmem.  But we're doing it anyway at present for consistency
      (ie: debug coverage) and because the filemap.c pagecache copying functions
      rely on kmap_atomic() disabling do_no_page() for all pages: see
      do_no_page()'s use of in_atomic()).

      [PATCH] reiserfs: fix savelinks on bigendian arches · 3491b2bc
      Andrew Morton authored
      From: Oleg Drokin <green@namesys.com>
      
      This small patch fixes a savelinks problem on bigendian platforms, where
      savelinks were not working at all because of incorrect cpu->disk endianness
      conversion.
      
      Savelinks are used on reiserfs to remember "truncate" and "unlink" events
      so that if crash happens in the middle of truncate/unlink, we do not endup
      with lost or half truncated files.

      [PATCH] dm: 64 bit ioctl fixes · 35a4a8e8
      Andrew Morton authored
      From: Joe Thornber <thornber@sistina.com>
      
      Update the ioctl32 handlers for the 64-bit architectures to recognize
      the new Device-Mapper version 4 ioctls. The version 1 ioctls are still
      there.  If/When the version 1 ioctls are removed, these same files
      will need to be updated again.
      
      I have been unable to test this patch yet, since I have not had any
      luck getting 2.6.0-test2 to compile on my ppc64 box (not a dm-related
      problem).  But the patch is pretty trivial, so I'm pretty confident it
      will work. If anyone else can test this (on mips64, sparc64, parisc,
      or x86-64), let me know if you have any problems.  [Kevin Corry]

      [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] 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.

      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

      like this got fixed and not brought forward.
