bc9e7c3b42 Fixed double counting of runtime after a process exits. The last 
timeslice of the exiting process was counted for both the exiting
process and the next process to run if the next process runs
immediately.

Broken in:	mostly in kern_clock.c rev.1.70 (1998/05/28)

f80a0a922c Re-arrange the page layout used by vm86_bioscall so that we can 
potentially re-use the stack page.

Cosmetic cleanup of the code to de-obfuscate it and make it easier
to follow.  There should be no functional changes in this commit.

3f47ee5c4d A better solution to the rm_at_exit problem: Register the exit function 
during first mount.  Unregister the exit function at last unmount.

f69c53b019 Don't pass the label to diskerr(), since the label is being constructed 
and may be invalid.  In particular, d_secpercyl may be 0, and diskerr()
divides by it.

72c36e1413 Fix pmap_enter_quick() to stop it hanging when the level 2 pte exists 
but isn't valid.

Reimplement pmap_remove() to be much more efficient at removing large
stretches of addresses.

As part of reimplementing pmap_remove() fix pmap_protect() so that it stands
a hope of working.

df9efa9a8b On the alpha, ports may be allocated above 64k. 
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386.  This is a stopgap with a
hopefully limited lifetime.

7cb743ae28 Initialize more defaults for the in-core label for the whole disk. 
Callers only need to initialize d_secperunit now, but should
initialize d_type (to reduce the IDE/SCSI confusion), d_typename
(put the disk model in it) and geometry info (if it isn't completely
ficticious).  Callers will soon need to initialize d_secsize.
