Jes Sorensen e723ccd805 [PATCH] sem2mutex: drivers/scsi/ide-scsi.c
Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

Christoph Hellwig 6a2900b676 [PATCH] kill cdrom ->dev_ioctl method
Since early 2.4.x all cdrom drivers implement the block_device methods
themselves, so they can handle additional ioctls directly instead of going
through the cdrom layer.

Alan Cox 09c7ad79dc [PATCH] libata: Fix a drive detection problem
The current code follows the spec but uses an overlong delay. This would
be great if the hardware did. Several vendors however forget the D7
pulldown. Fortunately 0xFF isnt a sane reset state so we can use it to
skip detection as is done in drivers/ide. (ie this is a tested solution
over a long time)

Nick Piggin f9aed0e253 [PATCH] sg: use compound pages
sg increments the refcount of constituent pages in its higher order memory
allocations when they are about to be mapped by userspace.  This is done so
the subsequent get_page/put_page when doing the mapping and unmapping does not
free the page.

Move over to the preferred way, that is, using compound pages instead.  This
fixes a whole class of possible obscure bugs where a get_user_pages on a
constituent page may outlast the user mappings or even the driver.

Christoph Lameter ac2b898ca6 [PATCH] slab: Remove SLAB_NO_REAP option
SLAB_NO_REAP is documented as an option that will cause this slab not to be
reaped under memory pressure.  However, that is not what happens.  The only
thing that SLAB_NO_REAP controls at the moment is the reclaim of the unused
slab elements that were allocated in batch in cache_reap().  Cache_reap()
is run every few seconds independently of memory pressure.

Could we remove the whole thing?  Its only used by three slabs anyways and
I cannot find a reason for having this option.

There is an additional problem with SLAB_NO_REAP.  If set then the recovery
of objects from alien caches is switched off.  Objects not freed on the
same node where they were initially allocated will only be reused if a
certain amount of objects accumulates from one alien node (not very likely)
or if the cache is explicitly shrunk.  (Strangely __cache_shrink does not
check for SLAB_NO_REAP)

Getting rid of SLAB_NO_REAP fixes the problems with alien cache freeing.

Basically, sata_mv was looking in the wrong place for

  - add a "t10 vendor id based" designator as defined in
    SAT rev 08 (section 10.3.4.2.3) that supplies ATA
    model and serial numbers
  - make the libata VPD page 0x83 more extensible (for
    adding more designators in the future).
  - rename EVPD to VPD in various places. Enable Vital
