The Pegasos firmware doesn't create a valid "ranges" property for the
ISA bridge, thus causing translation of ISA addresses and IO ports to
fail. This fixes it, thus re-enabling proper early serial console to
work on Pegasos.

This patch fixes the front-LED Kconfig issues I introduced while
creating it. Apparently having a dependency isn't enough to have the
select not evaluated or something like that.

The patch also changes the default configuration for pmac32 select the
default for the LED to be the IDE trigger. While I was at it, I
completely updated the defconfig and also added snd-aoa to it.

1) Explicitly traverse to the root looking for the "sbi".
2) Grab the "board#" property from the sbi's parent and
   verify that this parent is an "io-unit" node.
3) Skip IRQ initialization when device lacks "reg" property.

On sparc32 the prom_{first,next}prop() interfaces work
a little differently.  The buffer argument is ignored on
sparc32 and the firmware just returns a raw pointer to
the property name.

Sabre and Psycho PCI controllers can have partial interrupt-map
properties, meaning that on-board devices don't match up to any
entries.  Instead, they are fully specified from the beginning and
we should pass them directly to the IRQ translator as-is.

Also, fill in the necessary translator slots for the "graphics"
and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.

Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.

Finally, prevent accidentally writing past the end of the of_device
struct resource[] and irqs[] arrays.  Spit out a log message when
we ignore some entries because there are too many of them.

Some -mm-only material leaked into a patch destined for mainline, and I didn't
notice.

This was the replacement of system_utsname with utsname() that's required by
the uts namespace patch.  This patch reverts those changes (which are correct
in -mm) so that mainline UML builds again.

On i386, the user space accessor functions copy_from/to_user() both invoke
might_sleep(), do a quick sanity check, and then pass the work on to their
__copy_from/to_user() counterparts, which again invoke might_sleep().
Given that no actual work happens between these two calls, it is best to
eliminate one of the redundant might_sleep()s.

This patch removes the foolish assumption that SMP implied local apics.
That assumption is not-true on the Voyager subarch.  This makes that
dependency explicit, and allows the code to build.

What gets disabled is just an optimization to get better crash dumps so the
support should work if there is a kernel that will initialization on the
voyager subarch under those harsh conditions.

Hopefully we can figure out how to initialize apics in init_IRQ and remove
the need to disable io_apics and this dependency.
