TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion
between the two as was always intended. buf I/O's that can't be
started get pushed back onto the front of the queue and retried.
Others get sent back to originator as failures. No more epi-cycle
looping inside the SCSI midlayer hoping the problem goes away.
Various testers, no objection from miod@ as vs(4) was tested by

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.

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.

This is a noop on all arches but hp300, where this fixes (at least) IPL_BIO
mutexes.

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

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

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.

in the manual page are defined on all platforms as well.

1) The sysctl allowing bufcachepercent to be changed at boot time.
2) The change moving the buffer cache hash chains to a red-black tree
3) The dynamic buffer cache (Which depended on the earlier too).

These values were used to eventually pass ranges to uvm_pglistalloc(),
which has been fixed to correctly skip no-memory ranges a lot of time ago;
however mvme68k would still use the computed range and osiop would no
longer attach; this repairs it.

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.

recent driver work; this gives us better osiop and vs drivers, vsbic
(although currently disabled on 68060 boards until more bugs are fixed),
and the ability to boot and root off vs and vsbic.
Existing code is not modified and still uses memory mapped structures;
this might change eventually as more code gets factorized and moved to
MI land.
