There are some scattered implicit RASTERCONSOLE dependencies,

14ee4005a1 make sp_tlb_flush() work for profiling kernels: 
when we're profiling, the compiler creates a stack frame for us,
so doing a "retl" isn't so good in that case.

939df36e55 add support for non-executable mappings (where the hardware allows this) 
and make the stack and heap non-executable by default.  the changes
fall into two basic catagories:

 - pmap and trap-handler changes.  these are all MD:
   = alpha: we already track per-page execute permission with the (software)
	PG_EXEC bit, so just have the trap handler pay attention to it.
   = i386: use a new GDT segment for %cs for processes that have no
	executable mappings above a certain threshold (currently the
	bottom of the stack).  track per-page execute permission with
	the last unused PTE bit.
   = powerpc/ibm4xx: just use the hardware exec bit.
   = powerpc/oea: we already track per-page exec bits, but the hardware only
	implements non-exec mappings at the segment level.  so track the
	number of executable mappings in each segment and turn on the no-exec
	segment bit iff the count is 0.  adjust the trap handler to deal.
   = sparc (sun4m): fix our use of the hardware protection bits.
	fix the trap handler to recognize text faults.
   = sparc64: split the existing unified TSB into data and instruction TSBs,
	and only load TTEs into the appropriate TSB(s) for the permissions.
	fix the trap handler to check for execute permission.
   = not yet implemented: amd64, hppa, sh5

 - changes in all the emulations that put a signal trampoline on the stack.
   instead, we now put the trampoline into a uvm_aobj and map that into
   the process separately.

originally from openbsd, adapted for netbsd by me.

c43b35423e Pass pointers to frames from assembly, do not use the 'frame on stack 
as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions
about the stack that will not be true. Costs 2 instructions per trap/syscall
on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64,
2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better
optimization (it'd better..)

While here, make amd64 compile again by using subr_mbr_disk.c

I doubt it makes much sense to use the VM's stack for this, but the
old code was doubtless wrong because it potentially overwrote random
user memory.
(It might be a good idea to use the process' pre-vm86()-call stack,
but atm the infrastructure for this is missing.)

to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.
