Keyword substitution: kv
Default branch: MAIN

Convert the Alpha port's bus_space back-end to manage address space
with vmem(9) arenas (using statically-allocated private boundary tags
for very early-in-boot) rather than extent(9).

As a side-effect, there's arguments to some initialization functions
that are no longer required, so garbage-collect those, update all the
call sites.

Sync with HEAD.

On LCA45 systems, look at the memory controller's Bcache configuration
to initialize uvmexp.ncolors rather than hard-coding a value per model
(some models can have more than one configuration).

sync with head

merge to -current.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

Catchup with rmind-uvmplock merge.

Major cleanup of alpha device drivers.
Switch to CFATTACH_DECL_NEW.
struct device * -> device_t
struct cfdata * -> cfdata_t
Use of device_xname.  No direct access to struct device members.
Use aprint* (not complete).

Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.

Sync with HEAD.

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Update marc-pcmcia branch from trunk.

Treat bus space tags more like pci chipset tags and bus dma tags: allocate
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

syng thorpej-bus-dma changes with alpha-nwscons branch

Pull thorpej-bus-dma branch into mainline.

Update for pci_pte*_sgmap -> pci_sgmap_pte* change.

- Adopt to new common sgmap code.
- Fix several bugs, and reduce housekeeping overhead.

sync the nwscons branch up with yesterday's version of the trunk.
Lots of conflicts/changes because of the RCS Id format changes.
Also, a few cleanups and corrections.

Add DMA-related structures.

clean up NetBSD RCS ID strings

update for new extent management code, and for apecs/lca space access fn split

update for new bus.h macros.  bus_io_* and bus_mem_* integrated into
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

clean up copyrights and RCS IDs

partially update for new ISA/EISA/PCI and 'bus' interfaces.  not yet
complete, or tested.

wholesale update from my NetBSD/Alpha source tree.  Includes:
	Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
