Tweak for better performance when data is in L2 or L3 cache.

Patch below should apply to both the 2.5.7-pre1 and 2.4.18 trees.

all APs (based on patch by Bjorn Helgaas).

changes:
* EFI_GUID macro defined per your suggestion - efi_guid_t is now a struct of
char[16].  Fixed all GUID definitions.
* Made one unified efi_guid_unparse() static inline in asm-ia64/efi.h.
Removed three other definitions of similar in efivars.c and mca.c.
* fixed endianness of fs/partitions/efi.c - thanks to Richard Hirst and his
GPT work in Parted.
* cleaned up find_valid_gpt() to make it easier to see what's going on and
avoid future NULL ptr deref cases if this code gets modified yet again.
* Only use partition table slots 0..max_p.  The previous behaviour would let
you delete a partition in the middle of the table, and on next boot all the
partition numbers above that would switch down.  This change makes it
consistent with the MSDOS concept of primary partitions.  /dev/sdaX exists
iff the partition type is not NULL.
* Moved CONFIG_PARTITION_EFI help text to fs/partitions/Config.help

The texts were obtained from Eric S. Raymond's v2.97 Configure.help.

	Update for v2.5.7.

This patch remove unused variable/function/define, and small indent
cleanup.

The following patch moves MSDOS_SB() and MSDOS_I() into #define
__KERNEL__.

- Apply more patches from Vojtech Pavlik for the handling of host chip setup.
   Hopefully they are settled now.

- Kill unused CONFIG_BLK_DEV_MODES

- Push register addressing down in to task_vlb_sync.

- Make the taskfile parsing stuff actually readable. This is compressing the
   code by an incredible amount. We use just one function doing the whole
   scanning right now. This should make sure that the IRQ handler used by a
   particular command is always right.  I didn't introduce typos hopefully
   here.

- Don't call ide_handler_parser as argument for do_taskfile() any longer. We
   have killed this function by coalescing it's functionality with
   ide_cmd_type_parser() anyway.

- Kill unused SLC90E66 code, which Vojtech apparently missed in his patch.

- sync up with 2.5.7-pre2

Once again the actual patch is rather big mostly due to the removal of
some default configuration variables which are not used anylonger. So time for
the next patch stage.

- add joystick support for CS46xx driver
- Audigy code updates
- fix sound/core/Config.in (wrong dep_tristate usage)
- rawmidi interface fixes (memory leak)
- chang spinlock to rwlock in pcm_native.c (streams linking)
- further fixes of dependencies in Makefiles
- remove experimental time-sync support from sequencer
- fix/update for 32-bit -> 64-bit ioctl converter code
- wavefront driver cleanups
- CMIPCI driver updates
- update joystick support in CS4281
- add detection (not support) of M Audio Delta1010LT
- add AMD768 PCI ID to intel8x0 driver
- add joystick code to trident driver
- remove static variable initialization to zero

This adds initial driverfs support to ISAPNP driver.  It was approved by
the ISAPNP maintainer (Jaroslav Kysela).

I got burnt one too many time by mismatches between
the pci_pool and "real" slabs... something changed in
mm/slab.c and broke a driver, so I'm going for the real
fix this time.  Having poisoning that _works_ is a huge
help in the innards of the USB host controller drivers.

This patch gets rid of some #ifdefs and makes the pci_pool
code poison memory if CONFIG_DEBUG_SLAB is set.
The functionality has always been there, but this makes
it simpler to get at.
