This adds sound support for some of the newer PowerBooks.  It appears
that this chip supports the AWACS sample rates, but has a snapper-style
mixer.  Tested and works on my PowerBook5,4.

This is the PPC64 counterpart of the PPC32 Altivec assist exception
handler that went in recently.

On PPC64 machines with Altivec (i.e.  machines that use the PPC970 chip,
such as the G5 powermac), the altivec floating-point instructions can
operate in two modes: one where denormalized inputs or outputs are
truncated to zero, and one where they aren't.  In the latter mode the
processor can take an exception when it encounters denormalized
floating-point inputs or outputs rather than dealing with them in
hardware.

This patch adds code to deal properly with the exception, by emulating
the instruction that caused the exception.  Previously the kernel just
switched the altivec unit into the truncate-to-zero mode, which works
but is a bit gross.  Fortunately there are only a limited set of altivec
instructions which can generate the assist exception, so we don't have
to emulate the whole altivec instruction set.

Note that Altivec is Motorola's name for the PowerPC vector/SIMD
instructions; IBM calls the same thing VMX, and currently only IBM makes
64-bit PowerPC CPU chips.  Nevertheless, I have used the term Altivec in
the PPC64 code for consistency with the PPC32 code.

The code in radeonfb looking for the BIOS image currently uses the BIOS
ROM if any, and falls back to the RAM image if not found.  This is
unfortunatly not correct for a bunch of laptops where the real panel
data are only present in the RAM image.

This works around this problem by preferring the RAM image on mobility
chipsets.  This is definitely not the best workaround, we need some arch
support for linking the RAM image to the PCI ID (preferrably by having
the arch snapshot it during boot, isolating us completely from the
details of where this image is in memory).  I'll see how we can get such
an improvement later.

This adds support for newer Apple laptop models.  It adds the basic
identification for the new motherboards and the cpufreq support for
models using the new 7447A CPU from Motorola.

This is mostly the work of John Steele Scott <toojays@toojays.net> with
some bits from Sebastian Henschel <linux@kodeaffe.de> and some rework by
myself.  Please apply,

Certain early SATA drives have problems with write requests whose
length satisfy the equation "sectors % 15 == 1", on the SiI 3112.
Other drives, and other SiI controllers, are not affected.

The fix for this problem is to avoid such requests, in one of three
ways, for the affect drive+controller combos:
1) Limit all writes to 15 sectors
2) Use block layer features to avoid creating requests whose
   length satisfies the above equation.
3) When a request satisfies the above equation, split the request
   into two writes, neither of which satisfies the equation.

I chose fix #1, the most simple to implement.  After discussion with
Silicon Image and others regarding the impact of this fix, I have
decided to remain with fix #1, and will not be implementing a
"better fix".  This means that the affected SATA drives will see
decreased performance, but set of affected drives is small and will
never grow larger.

Further, the complexity of implementing solution #2 or
solution #3 is rather large.

When implementing lba48 'large request' support, I unintentionally
broke the fix for these affected drives.  Kudos to Ricky Beam for
noticing this.

This change restores the fix, by adding a flag ATA_DFLAG_LOCK_SECTORS
to indicate that the max_sectors value set by the low-level driver
should never be changed.

This patch adds back that support in the correct place by converting

Also clean it all up - use get_cpu()/put_cpu() instead of
playing games by hand with preemption.

Here is a simple patch which drops some out-of-date code in the w83781d
and w83627hf i2c chip drivers. These bits are left over from the times
when chip drivers were setting default limits at init.
