Use lwp_getpcb() on sparc{64} and sun2/3 MD code, clean from struct user usage.

Add a zero argument to pmap_kenter_pa() invocations.
According to cegger@ this is the right thing to do for the moment.

TRUE -> true, FALSE -> false

Replace the Mach-derived boolean_t type with the C99 bool type. A
future commit will replace use of TRUE and FALSE with true and false.

Fix botch in #ifdef DIAGNOSTIC.

Implement bus_dmamap_load(9) and bus_dmamap_unload(9) for sun3x.

KNF

First attempt at bus_space(9) support for sun3 with common sun68k/bus.c:
- make sun3 port use common sun68k files as much as possible
- add temporary options _SUN2_ in std.sun2 until sun3 can share all
sun68k files (autoconf.c and isr.c are not yet)
- move sun68kvme declaration temporary as well from files.sun68k to files.sun2
- rename and move sun68k_find_prom_map() function to MD sources since it
can't be shared with sun3
- add bus tag members to struct confargs and initilize them where appropriate

XXX1: MD bus_dma(9) backends are not implemented (yet).
XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

remove trailing \n in panic(). approved perry.

Don't use rmaps; use extent maps.

branches: 1.23.4;
replace pmap_enter() with pmap_kenter_pa() where appropriate.

Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

- vm_offset_t -> [pv]addr_t

Sprinkle pmap_update() calls after calls to:
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()

These calls are relatively conservative. It may be possible to
optimize these a little more.

splimp() -> splvm()

Fix printf formats in panic messages.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

remove/move more mach vm header files:

<vm/pglist.h> -> <uvm/uvm_pglist.h>
<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
<vm/vm_object.h> -> nothing
<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

Update for pmap_enter() API change. No functional difference.

branches: 1.13.2; 1.13.4; 1.13.8;
Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

branches: 1.12.4;
Changes for modified pmap_enter() API:
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot. Also, DO NOT use
pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
access_type = 0. This should probably be revisited.

completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

First cut at UVM support. Compiles, but not tested yet.

Change our DVMA map from the last 16MB to the last 1MB because that is
the only part that is visible to VME masters, and is adequate space.
This allows the "si" driver (on VME) to use DMA transfers.

When calling iommu_* functions, use IOMMU_VA_MASK.

Corrected typo in comments.

Add dvma_malloc() for the ie driver.
