he 319f2b1f1a Back out the previous, removing the wsfont pseudo-device added as part
of resolving PR#18388.  The shark port isn't quite wscons-ready yet.

OK'ed by thorpej.

thorpej bbba90a2fb Don't expose KERNEL_TEXT_BASE outside of board-specific code. This gives
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

thorpej 4eeee795e8 Eliminate PTE_BASE and the PT-PT completely in the ARM32_PMAP_NEW case.
Also in the ARM32_PMAP_NEW case, reclaim the USPACE-bytes of wasted space
at the top of the user address that hasn't been needed for a very very
long time.

thorpej bbef46a7e9 Some ARM32_PMAP_NEW-related cleanup:
* Define a new "MMU type", ARM_MMU_SA1.  While the SA-1's MMU is basically
  compatible with the generic, the SA-1 cache does not have a write-through
  mode, and it is useful to know have an indication of this.
* Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at
  compile time.  We evaluate it like so:
  - If SA-1-style MMU is the only type configured -> 1
  - If SA-1-style MMU is not configured -> 0
  - Otherwise, defer to a run-time variable.
  If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time
  check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly
  code can include the necessary run-time support.  PMAP_INCLUDE_PTE_SYNC
  largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve
  included with the original new pmap.
* In the new pmap, make pmap_pte_init_generic() check to see if the CPU
  has a write-back cache.  If so, init the PT cache mode to C=1,B=0 to get
  write-through mode.  Otherwise, init the PT cache mode to C=1,B=1.
* Add a new pmap_pte_init_arm8().  Old pmap, same as generic.  New pmap,
  sets page table cacheability to 0 (ARM8 has a write-back cache, but
  flushing it is quite expensive).
* In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to
  C=1,B=0, since the write-back check in generic gets it wrong for ARM9,
  since we use write-through mode all the time on ARM9 right now.  (What
  this really tells me is that the test for write-through cache is less
  than perfect, but we can fix that later.)
* Add a new pmap_pte_init_sa1().  Old pmap, same as generic.  New pmap,
  does generic initialization, then resets page table cache mode to
  C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.

drochner 66a5580c6e Remove remaining uses of libsa/netif -- the "netif" structure was only
used to lookup a "struct of_dev", everything else was ballast.
Do it straightforward now and assign the ofdev directly to io_netif.

perry 1f4ad37fe3 "Utilize" has exactly the same meaning as "use," but it is more
difficult to read and understand. Most manuals of English style
therefore say that you should use "use".

lukem 4bb41ae2f2 Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile.  Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

jdolecek c82ab2eb79 now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function

jdolecek e0cc03a09b merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

bjh21 d599df9587 Continue the " - . - 8" purge. Specifically:
add	rd, pc, #foo - . - 8		->	adr	rd, foo
ldr	rd, [pc, #foo - . - 8]		->	ldr	rd, foo

Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.

Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

chris 5dded94793 Fixup IPL_LEVELS to be correct. This matches the change I did to footbridge
based systems.  Untested on shark, but is the right thing to do.  I suspect
the original arm32 intr.h had the bug, and when the ports split we just took
the bug.
