6f4f08b8b2 Add a few more PALcode operations, as documented in pages (II-B) 2-1 through
(II-B) 2-33 of the Alpha AXP Architecture Reference Manual, Second Edition:

* rdps - Read Processor Status, needed by spl* functions.
* cflush - Cache Flush
* rdval - Read System Value
* wripir - Write Interprocessor Interrupt Request
* wrval - Write System Value

cflush, rdval, wripir, and wrval are used in multi-processor environments.

2c5c631b71 - Make the pmap_activate() and pmap_deactivate() interfaces consistent my
passing them a proc *, which encapsulates all of the information necessary
  to activate an address space.
- Garbage-collect pmap->pm_stchanged; it's not really used for anything.

8b6e894364 Clean this up a bit; defopt has rendered the #undef hacks unnecessary.
Also, put the cpu_decl()s in cpuconf.h, so that platform support files
can pull in the prototypes from there, and pull in options for those
systems for which there is code in the source tree.

395f4bac6b clean up bootinfo structure comments so they're more readable (to me,
at least 8-).  Add structure offssets for structure members, so we
know how much space we're using.  Make the version in the bootinfo
structure be a u_long, so there's no implicit padding in the structure.
Add a few more pointers to the bootinfo v1 structure, which will all
be set to NULL for now.

28b1691f4d when i was documenting the bus_space interfaces (the document
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
    'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
    with other region ops.
Fix all of these (in a backward-compatible way, at least for now).  Redefine
internal usees of those names to use the new names.  Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.

1c33c6bff8 actually, declare _splraise() as an inline function, because:
(1) it was using 'max', and some functions use a variable
	    of that name (*sigh*), and
	(2) that makes it easier to be a bit trickier, and only call
	    swpipl if changing the IPL.

90789b53dd by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory.  (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
