Mainly adding the infrastructure for various ATA ioctls.  Currently
only supports two ATA-specific ioctls:
HDIO_GET_32BIT and HDIO_SET_32BIT (hdparm -c)

Abstract out PIO data xfer to xfer-a-sector and other-stuff pieces,
then add new ATAPI code that uses the common xfer-a-sector code.

We were reading the data swapped, which was correct for the
data page read from IDENTIFY DEVICE and incorrect for all other
situations.

Noticed by Ben Herrenschmidt.

Fixes two common boot failures due to buggy SMM BIOS code

SMP boot crash if SMI_CMD=ACPI written from CPU1

laptop crash due to LAPIC timer before SMI_CMD=ACPI

Also, remove BenH's email address from SiI driver, to reduce
email coming to him for a driver he didn't write (by request).

Update lasi 82596 driver:
 - Fix boot messages (Helge Deller)
 - Whitespace and __FILE__ usage (Joel Soete)
 - 64-bit compile warning fixes (James Bottomley)

This trivial fix allows mounting MO-drives readwrite.

The newly introduced ->fcntl file_operation is badly thought out,
not to mention undocumented.  This patch replaces it with two better
defined operations -- check_flags and dir_notify.  Any other fcntl()s
that filesystems are interested in can have their own properly typed
f_op method when they need it.

Patch from Marc Singer

The work already done to rectify the timer code initialization missed
a necessary change.  This patch adds a timer initialization function
to the LPD7A400 machine type.  It also makes a small correction to the
kernel configuration that is out of step with the machine specific
Kconfig.

Patch from Marc Singer

This patch aligns the lh7a40x port with the updated structure of IDE
drivers.  It also removes an unused FIQ handler.  This patch is made
in order to get the lh7a40x port to build.

Patch from Catalin Marinas

This patch replaces the -mshort-load-bytes option with $(call
check_gcc,-malignment-traps,-mshort-load-bytes) in the CFLAGS
setting in arch/arm/Makefile.

In the *ppos cleanups, proc_dol2crvec was updated, but the prototype
found at the top of kernel/sysctl.h was not, generating warning.  This
corrects the prototype to match the code.

(I'm gonna take a stab at moving these into arch/ppc shortly)

We allow more commands if the disk was opened read-write.

They'll need it for permission checking.

Normal users shouldn't have access to the raw device anyway
unless they are in the trusted "disk" group, but let's require
RAWIO capabilities. That's what the original SCSI interfaces
did anyhoo.

We probably _should_ just require write access, but that will
need more of a code change to pass down the file descriptor.

We must setup the queue before calling elevator_init(), otherwise the
elevator cannot use the queue members. This really hurts cfq since it
checks ->nr_requests, which is zero at that time.

With 'len' being unsigned now, we must make sure it never tries
