* Print notice if not all CPUs were attached
* Switch to SMP version of cache flush routines in just one place: in
cpu_attach() after all known CPUs have been configured.
- there's no need to have different PV_NC flags for sun4[c] & sun4m
- deal with kvm_uncache() being called on a managed page in a
separate helper function that deals with the caching state
within the pv list for that page, avoiding interference with
the `bad alias' removals in pv_unlink().
Note that currently never called for managed pages, but for now I'm
keeping the support in.
currently necessary to acquire the `running in kernel mode' lock;
pointed out by Bill Sommerfeld/Simon Gerraty.
* remove reference to `cpu_set_kpc()' from comments, as we don't have it.
* message buffer initialisation:
- change the buffer size to 8192 on all platforms
- don't assume the buffer is always located at physical address 0
- drop the SUN4 hack that left first half of the page unused;
I believe this is no longer necessary, since the msgbuf
data structure is duely sanity-checked before use in initmsgbuf().
structure. While this comes with the cost of having to search the
`vm_physmem' array every time need to find a PV entry corresponing to
some physical address, we gain the flexibility needed to support
arbitrary non-contiguous ranges of physical memory addresses.
Also, eliminate the need to sort the memory address ranges as presented
by the machine's PROM, and the requirement that physical memory starts
at address 0 (when possible).
file rather than requiring a raw device. Useful when dealing with vnd's
images and building snapshots. Also allows snapshots to be built in

This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards. This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.
This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver. I've tested it (briefly) with 'ei' on arm26
as well. In theory, drivers other than 'ix' should follow precisely the
same code paths as before.
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

enough, e.g. it has been initialized already by inittodr() or set
explicitly before by resettodr(). This prevents the TOD clock from going
way backwards when typing `halt' at the `mount root filesystem' prompt.
