7190ad9936 Fix a major bug in pmap_remove_kernel() that causd the removal of 
one page too many (worse, it unmapped our stack page... Ouch!)
Also, use loadcrp() and such instead of calling pmap_activate
in various places so we have more control over TLB flush.
Now pmap_activate() is called only by locore (and that call is
done only if PMAP_DEBUG is defined).  Other minor clean-up...

says we have an arg of type "frame" (big union), then KGDB will try to

Also add the function trap_kdebug() which takes care of calling one of:
kgdb_trap (for KGDB), or kdb_trap, (for DDB) or the Sun PROM monitor.
This logic used to be in locore, but it is better as C code.

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.
