649a90497e No need to check for CPU_ARM7500 being defined as this option implies 
CPU_ARM7 which has to be checked anyway.

e14a0d029f Add support for generating "option headers". These allow options to 
be included in object dependencies.  config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files.  Options that are placed in
header files are not given -D... cpp flags.

This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.

14a4465f0b - Implement _splraise(), like _spl(), but only modifies the SR if the 
new ipl is higher than the ipl currently set in SR.  (Thanks to
  scottr@netbsd.org for implementing it while I was busy with other stuff!)
- Define spl{bio,net,tty,imp} in terms of _splraise().
- Move definition of splhil() here, and define splkbd() as an alias for it.

e9eba07a8f Add the Utah mappedcopyin/mappedcopyout functions to a common m68k 
area.  These functions are designed to improve performance of large
copyin/copyout operations by mapping the user page in to the kernel
address space and using bcopy(), rather then copying across protection
boundaries.

XXX This doesn't work yet -- the way it's called doesn't obey C calling
XXX conventions.  That will be fixed soon.

7dae9fb29b Add two optimized functions used by pmap.c: 
- copypage() -- a single page-aligned NBPG-byte copy.
- zeropage() -- a single page-aligned NBPG-byte zero.
These functions don't play around with alignment, etc.  Their use
causes a measureable performance improvement in pmap_copy_page()
and pmap_copy_page().

A few m68k ports already had copypage() in their locore.s.  It has
been moved here so it can be shared.
