The underflow exception cases were wrong.

This is one weird area of ieee1754 handling in that the underflow
behavior changes based upon whether underflow is enabled in the trap
enable mask of the FPU control register.  As a specific case the Sparc
V9 manual gives us the following description:

--------------------
If UFM = 0:     Underflow occurs if a nonzero result is tiny and a
                loss of accuracy occurs.  Tininess may be detected
                before or after rounding.  Loss of accuracy may be
                either a denormalization loss or an inexact result.

If UFM = 1:     Underflow occurs if a nonzero result is tiny.
                Tininess may be detected before or after rounding.
--------------------

What this amounts to in the packing case is if we go subnormal,
we set underflow if any of the following are true:

1) rounding sets inexact
2) we ended up rounding back up to normal (this is the case where
   we set the exponent to 1 and set the fraction to zero), this
   should set inexact too
3) underflow is set in FPU control register trap-enable mask

The initially discovered example was "DBL_MIN / 16.0" which
incorrectly generated an underflow.  It should not, unless underflow
is set in the trap-enable mask of the FPU csr.

Another example, "0x0.0000000000001p-1022 / 16.0", should signal both
inexact and underflow.  The cpu implementations and ieee1754
literature is very clear about this.  This is case #2 above.

However, if underflow is set in the trap enable mask, only underflow
should be set and reported as a trap.  That is handled properly by the
prioritization logic in

arch/sparc{,64}/math-emu/math.c:record_exception().

Based upon a report and test case from Jakub Jelinek.

Add empty definition of mmiowb() since some drivers need it. Uncached
writes are strongly ordered on AVR32. They may be delayed if the
dcache is busy doing a writeback, but AFAICT that's not what this
macro is supposed to deal with, at least on UP systems.

We might have to revisit this definition when a SMP-capable AVR32 CPU
comes along, depending on how the busses and cache coherency stuff
end up being implemented.

The current definition of pte_page() masks out valid bits from the
physical address, causing vmalloc_to_page() to misbehave. This may
lead to everything from mmap() silently accessing the wrong data to
"invalid pte" errors dumped by the kernel.

Also remove the now-unused definition of PTE_PHYS_MASK.

Fix several inconsistencies in these drivers WRT reporting the clocks:

- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
  PCI clock -- make it properly report both clocks and add the same ability to
  the 'pata_hpt3x2n' driver;

- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
  messages -- make them use only the former one;

- the message about failed DPLL stablizatios deserves KERN_ERR and a bang. :-)

including mode 5 used to check for the necessity of 66 MHz clocking -- this

The 440 family of processors don't have a tlbie instruction.  So, we
implement TLB invalidates by explicitly searching the TLB with tlbsx.,
then clobbering the relevant entry, if any.  Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler.  Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries
which needed to be invalidated.

This fixes the problem in both arch/ppc and arch/powerpc by inhibiting
interrupts (even critical and debug interrupts) across the relevant
instructions.
