supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and
remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).
Based on a diff from tedu.

calls can go directly into selwakeup() safely
long discussion with nicm, murmers of consent from tedu and miod, noone
else seems to care of kqueue is busted as long as it makes their sockets
move data fast... pretty sad.

are very close to the Tsunami systems (rpb family 34) and share the existing
Tsunami code; the tsc(4) Tsunami controller code is extended to handle the
Titan differences, except for the Titan AGP GART which is left unsupported
for now.
Tested to not cause regressions on DS20 (deraadt@) and ES40 (miod@).
Titan support tested by Sergey Prysiazhnyi on DS25, many thanks for your time!

errnos. Note that the error strings are being ignored, since we long ago
decided to not spam the console, and there is no other nice way to use the
errors (without changing the ioctls to pass it back)
The errno is now useful, since we can pass b_error from failing IO up, and
the drive can decide how to use that

a few arches where toolchain limitations apply) will embed some symbolic
information about the various structs used within the kernel, and have
new ddb commands allowing struct display and some useful information
gathering. Kernel rodata increase varies accross platforms from ~150KB to
~300KB.
This option is not enabled by default.

No longer allocate a static amount of memory for messages in MD
boot path; message queues, message metadata, and message data now
all use dynamic memory, which means that runtime sysctls should now
be trivial to implement.
Since I'm going to be around all week to fix any breakage, this should
probably just go in now.

bounds information, ie. the zone of the disk that OpenBSD can use. Have each
pre-disklabel parser (MBR, DPME, or per-arch MD disklabel parsers) figure out
this area and pass it up to userland. Then, delete all the same disk parsing
code from disklabel(8) since the kernel passes it up. Lots and lots of - signs
in the disklabel(8) code.
Tested on as many platforms as possible, the fallout will be repaired as time
goes on. To test, use disklabel -d <drive> and validate that the bounds do not
overlap any boot blocks. This same information is used by disklabel -A...
OK for the concept from krw, miod, and drahn

For the possibility of sleeping, the first two flags are UVM_PLA_WAITOK
and UVM_PLA_NOWAIT. It is an error not to show intention, so assert that
one of the two is provided. Switch over every caller in the tree to
using the appropriate flag.
