d48cc1feee Style fixes and a bug fix: don't remove the exit handler if unmount 
fails.

d3ce1542c8 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)

d757cde4ed 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.

be85829abc A better solution to the rm_at_exit problem: Register the exit function 
during first mount.  Unregister the exit function at last unmount.

f424d5f084 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.

02ecd6d029 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.

8f5a35b01d 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.
