- Remove unneeded breaks
- Fix double spin_unlock_irqrestore problem

Achieves the same result.  From Lenz Grimmer at Mysql AG

Plus with a little codeshuffling, we can do away with the
prototypes.

  "While diagnosing an MMX/FPU problem I found a minor problem in the
   code which diagnoses and generates signals for FPU exceptions.  On
   x86 Stack Fault Exception are a subclass of Invalid Operation.  Thus,
   the FPU status register will have both the SF and IF bits set when a
   stack fault occurs.  The code which turns FPU exceptions into signals
   was assuming IF would be clear".

The following patch has been floating around forever.  It is required
for several ARM framebuffer drivers, and several other drivers.  James
has indicated that this is the correct fix back in May.

This provides the necessary infrastructure for PowerMac specific drivers
(and actually some Open Firmware platform drivers on non-PowerMacs as
well provided somebody port them) to be properly probed & referenced via
the new driver model and be part of sysfs.

As-is, this patch doesn't break anything nor change any driver.  I'll
send you individual driver patches as I clean them up & get them tested
on as many machines as possible, though I don't expect much problems.

While reviewing my 2.4 backport of the 2.6 cpu capabilities (including
the Via RNG support), Mikael Pettersson noticed a bug in both my
backport, and 2.6:  when NCAPINTS (x86_capability array size) is
increased, one must adjust the offset in arch/i386/kernel/head.S also.

This makes the HISAX ST5481 driver build again with 2.6.0-test3 where
the usb_host_config structure has changed.
