ccbbd9271b Fixed two spl nesting bugs. They caused (at least) the entire pageout 
daemon to run at splvm() forever after swap_pager_putpages() is called
from vm_pageout_scan().

Broken in: rev.1.189 (1998/02/23)

51f14853fd Record the new physical address of the pcb in pmap_swapin_proc. 
Third attempt at pmap_remove().  This one actually works properly :-).

358cb8ddc1 I have a PD drive (Matsushita PD/CD Drive LF-1600). 
The machine can not recognize this PD drive
as neither PD drive nor CD-ROM Drive.
So I can not use CD-ROMs and PDs from FreeBSD.

f88a03565a Add wrappers for i386_*_ioperm, i386_vm86 so userland code does 
not have to call sysarch() directly.
Added man pages for above, as well as sysarch()

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.

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

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.
