c7d356a55e Clean up how the ROM is mapped. If the ROM falls in the large mapping 
we enter for the memory, use a subregion of that, else map it by itself.

70b5675025 Assembly version of ffs(3). 
Confirmed to return the same value as that of the C version.

The results of a simple benchmark on SH-4 200MHz, is shown below.
I think this shows acceptable performance.

ffdedb6d80 In pmap_map_in_l1() and pmap_unmap_in_l1(), make sure that the VA 
that is passed in is already aligned to a 4M super-section.

d158b3a37a When we allocate a PTP, make sure the offset we specify is for 
the 4M super-section that the PTP will map, not some random 1M
chunk of it.  This gives the PTP hint code a much better chance
to working properly, and allows us to tidy up the code that
flushes a PTP from the cache in pmap_destroy().

aafe6e006c Define macros describing the 4M super-sections that our pmap 
actually uses (since we allocate PT pages in 4K chunks, rather
than 1K chunks).

77a6866508 Enable caching on kernel and user page tables. This saves having 
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

a71473b576 Add autoconfiguration glue for the Sun4d "cpu-unit". Each processor 
board has 2 CPU units (one for each processor), one of which also has
a "bootbus", to which the serial ports, etc. are attached.

We can now probe/attach CPUs on a SPARCserver 1000.

76f5313c64 in start_init(), if RB_ASKNAME is set in boothowto, ask for the path 
name to start up as init (rather than just cycling thru initpaths[]
and panicing when out of options).  if RB_ASKNAME isn't set, the old
behaviour remains.  inspired by changes in der Mouse's patchtree.
resolves [kern/18027] from me.

78581fe411 In amap_ref, only increment the amap's refcnt after we have established 
the ppref array.  Otherwise, the newly ref'ed pages will be doubly
counted and thus never freed because the pprefcnt can't fall to 0.
