the newly-allocated msgbuf. (Note, it happened to work before
because nothing used pte afterwards, but in the event something
is added that does, pte should be correct.)
user; the boot blocks don't work when built with e.g. -mcpu=i486
(probably due to how branches are aligned in that case, causing
segment boundaries to be crossed).
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).
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.

Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).
there are other architectures (e.g. IA64) which also use PXE.
* Get the console right in pxeboot, from Andreas Gustafsson.
* Add a "com0" version of pxeboot, to address the same issue that
biosboot_com0 addresses.
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
* Add separate directories for the individual netboot ROMs and
always build them.
* Each bootloader Makefile explicitly specifies the start file
and link address it wishes to use.
* genprom becomes a proper host program.
* Make sure all generated files get cleaned up.
* Set BINDIR in Makefile.inc
* Add compressed image support to pxeboot.
* Make pxeboot use the default serial console speed (9600).

Still needs some work, but this will load a kernel on a Soekris net4501.
Many thanks to Frank van der Linden and his simulator wizardry for
helping me debug the low-level startup code.
