This is the rest of the work to make the driver not care which
version of the OS it's using, so the difference between the 2.5
and 2.5 versions can just be a small patch with stuff that has
a real need to be different.

The 2.5 version branched from 2.4.5 or so, and since then
a couple hardware-specific tweaks were merged to 2.4; this
teaches 2.5 about NatSemi SUPERIO and PA-RISC quirks.

This also uses os/version neutral HCD calls to register the root
hub and find the HCD's bus.  It also adds os/version neutral
macros for its diagnostic macros.  Most of those changes have
been split out separately, but the macros and a few uses of them
weren't naturally splittable.

Also a couple minor cleanups, like removing CVS ids, having
only one copy of a routine used with the debug files, and
getting rid of some inline #ifdefs.

This potentially helps debugging, since otherwise a double fault
would generate a triple fault and then reboot the machine. Now
instead it can print out a note about where the problem happened,
unless all the kernel data structures are truly buggered.

it's a noop in 2.5 now that the behvaiour of implicitly exporting
all symbols is gone.

This patch removes the devfs interface code in mtrr that has been
stubbed out by an ifdef forever.  It's one of the few remaining users
of regular files on devfs so there's some urge for me to get rid of it :)

Use cdevname instead in the serial driver printk cut & pasted into about
a dozend places.

small updates to bring us nearer the lm_Sensors CVS (docs, comments,
missing statics, named initializers).  I still need to review their
actual code changes before submitting those..

regular linux buffer cache here.

use more hash buckets for holding xfs metadata, and use the same
hash algorithm as the regular buffer cache.
