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..

the number of metadata buffers. Use the same techniques as the
regular linux buffer cache here.

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

this was always there, but exposed by the last change in
this area and made much more likely.

in pagebuf, should now be resolved.

The compiler.h fragment should describe the problem well enough.
