* On the 601, obliterate all BAT entries when returning from kernel to
...
userlevel; this is necessary due to the 601, unlike other 6xx, having
no concept of separated Valid_user vs. Valid_supervisor for BATs.
* When crossing the kernel/userlevel boundary, have platform-provided
hooks set up the two fixed BAT entries, and possibly additional
segment registers to redeem the 601's BAT limitations.
Both of the above are only built if the $MACHINE provides these hooks,
sparing others the pain.

Pool deals fairly well with physical memory shortage, but it doesn't
...
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.

Change defaults for kernel compiles. Default all to USETOOLS?=no and have

This way the default for kernel compiles is still to use the installed

Adjust each ports template to set the default no setting and also pull in

If _SOFT_FLOAT is defined, pull floating point va_args from the GPR

area and not the FPR area (by having the double argument type test
always fail).
Fixes problems using <stdarg.h> with -msoft-float.

- use "U" suffix for unsigned constants
- use "L" suffix for long constants
- use "UL" suffix for unsigned long constants

Avoid nesting structure declarations, where the nested structur is used at

the global level later. Besides stylistic matters, this actually breaks C++
programs (indirectly) using this header.

* Move definitions of exact-width integer types from <machine/types.h>
...
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.
