- this one is interesting and will play in the next series as well;
   affected place is fs/block_dev.c::do_open().  We check if bdev is
   a partition (same way it is done in generic_make_request()) and
   if it is - open entire disk and put pointer to its bdev into a
   new field bdev->bd_contains.  Otherwise (non-partition) we
   set bdev->bd_contains to bdev.  Corresponding cleanup done in
   blkdev_put() (and failure path in do_open()) - when the last opener
   goes away we close bdev->bd_contains if bdev is a partition (i.e.
   not equal to its ->bd_contains) and set it to NULL.
   Immediate effect is that we can get from bdev of partition to
   bdev of disk when submitting a bio, but it also opens a way
   to handle partition-parsing in a sane way.  That will be done
   in the next series.

 - md/raid1.c - bring struct block_device * into private data.

 - md/multipath.c convert to bio, compile fixes, bring struct
   block_device * into private data.

 - switch loop_set_fd() to struct block_device

 - switch blk_{get,set}_readahead() to struct block_device *

 - switch block_ioctl() to struct block_device *

 - new helpers: queue_hardsect_size() and bdev_hardsect_size().  Analogous
   to get_hardsect_size() for queue and struct block_device * respectively
   Most of get_hardsect_size() callers converted to these.

 - remove abuses of blksize_size[] and (late) hardsect_size[].  Mostly
   drivers/s390/char/*, BTW...

Remove unnecessary linux/bitops.h from fat/inode.c.

This patch cleans up fat_clusters_flush().

This patch does misc cleanup.

This patch makes detection of a FAT filesystem more exact by checking
the first FAT entry. 

Currently fatfs disregards most wrong cluster chains, and only continues
processing. 

This fixes it.  If a wrong cluster chain is detected, change filesystem
to the read only, and return the error code. 

 - Revoke the TCQ stuff. Well having it for some time showed just nicely what
   has to be done before it can be included cleanly. But it's just not ready
   yet.

   For more explanations please simply track the usage of the special field of
   struct request - *both* in the generic request handling code and in overall
   driver code.

Reduce cacheline bouncing when a dentry is in the cache.

Specifically, the d_count reference counter is not incremented and
decremented for every dentry in a path during path walking if the dentry
is in the dcache.  Execcisve atomic inc/dec's are expensive on SMP
systems due to the cachline bouncing.

Forward port changes from 2.4.19-pre, originally by Keith Owens.
This driver used to build a module target called "aic7xxx_mod.o" and
introduced the MOD_TARGET variable to rename it to "aic7xxx.o" at
modules_install time.
    
Now, we just build "aic7xxx.o" directly, which becomes possible after
renaming aic7xxx.c to aic7xxx_core.c, as done in 2.4.19-pre.

This patch fixes up some lose ends left over from the last x86-64 jumbo merge.

 - make it compile again. ia32_ioctl was referencing IDE ioctls that got
   remove in a merge race
 - Use the memset/FXRSTOR way to initialize the FPU, as discussed.
 - Fix semctl/shmctl ABI (thanks to Andreas Schwab)
 - Other minor fixes.

  This fixes compile errors.  It has been tested with a weekend of Bonnie++ 8GB
runs on a RAID0 setup at the OSDL.  This was built against and tested on 2.5.8
and applies cleanly to 2.5.9.

  LSI told me they have a version 2.0 of the driver in development but
it would be really nice to have the dang thing working now ;-)

Fix a few spelling mistakes in documentation (arch/i386/boot/setup.S,
Documentation/sysrq.txt).

Move BKL into the fs-specific write_super()'s.

As we discussed some time ago, here is a patch for the SEM_UNDO change
that can be applied to linux-2.5.9.

warnings for proper usage.

No object-code changes, but removes warnings from the stricter
typechecking.

Now it really works (I tried).

  Make sure that flush_tlb_range is called with PTL held.
  Also, make sure no new threads can start up in user mode
  while a tlb_gather_mmu is in progress.

Currently, if dependencies for one object file listed in $(export-objs)
change, we will rebuild all $(export-objs) files in the same subdirectory,
which may take a noticable amount of time and thus is annoying during
development, and, of course, unnecessary.

The patch is originally from Russell King and has been tested in the ARM
kernel tree for a long time.
