72a24b4eae Add an align argument to uvm_map() and some callers of that 
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

efef8a5aa6 Do not save t* registers in syscall stub as suggested by cgd. Saves 
a whole 0.01us in lmbench lat_syscall null on our 250Mhz QED system.
$at is still saved just to be safe, although it looks like it does
not need to be.  $v1 is used in syscall(), although I'm not sure why.

it look at casual inspection like 1 nop is needed but play other tricks.

2fc18ed7a4 Replace the old db_memrw.c with the hp300 version, modified for i386

7f3786d36a Add preliminary support for the MVME162-LX 200/300 series of boards. 
Currently, the major onboard devices are supported (disk, network,
rs232 and VMEbus). However, work is still need to support the remaining
devices (eg. IndustryPack sites).

These boards are available with a dazzling array of build options. At
this time, the following options are *required*:

	o Real floating point hardware (the 68LC040 model isn't tested),
	o The VMEchip2 must be present,
	o If offboard VMEbus RAM is not present, at least 8MB of onboard
	  RAM is required.
	o Even if offboard VMEbus RAM *is* present, at least 4MB of onboard
	  RAM is required. (Boards with 1 or 2MB onboard RAM *can* be
	  supported with offboard RAM, but not without some funky values in
	  the VMEbus Master mapping registers.)

There is no support for boards other than those in the -LX 200/300 series.
