generally translates to "high interrupt load") -- the old code re-enabled
interrupts in the machine-specific hardware interrupt handler causing the
handler to be re-entered, possible multiple times. Could lead to kernel
stack overflows, and all sorts of mysterious crashes/hangs as a result.
While here, fix up the IP32 interrupt handler code to also not re-enable
interrupts.
Thanks for ideas/comments go to Chuq and Stephen Ma.

the magic "files include order" dance in N machine-dependent
configuration definitions.
become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
- Build an ECOFF version of the bootloader as "boot". As a temporary
measure (due to a bug in libbfd which has not yet been fixed, but
for which a work-around exists as a patch), install and ELF version
of the bootload as well as "boot.elf". "boot.elf" will go away once
the toolchain issue is resolved.
info along to the kernel (currently just the symbol table info).
- Don't bother with the startprog dance; we don't need to do anything
special, here, so just call the entry point directly.
- A bunch of random cleanup.
save off DDB symbol table information.
- Make loading of memory work reliably with the bootloader; for each
candidate memory type from ARCS (which now includes LoadedProgram),
check to see if the kernel is within that chunk, and load the pages
around it if it is.
