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

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.

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.

commits:
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.

MD code would free resources that couldn't be freed until we were no
longer running in that processor. However, it's is unused on all
architectures since mikeb@'s tss changes on x86 earlier in the year.

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.

What happened was that the output of mkdep was fed to a sed expression
that trimmed a bit more than required and also failed to work when
attempting to do make depend with pcc.
Example:
genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \
was changed to:
assym.h: \
but what was intended was:
assym.h: ../../../../../sys/param.h \
For the pcc -M output things were a bit different and after the make
depend the genassym entry would still remain and make would fail. This
affected all platforms except amd64 and sgi.
Okay miod@.

Move calling ether_ioctl() from the top of the ioctl function, which
at the moment does absolutely nothing, to the default switch case.
Thus allowing drivers to define their own ioctl handlers and then
falling back on ether_ioctl(). The only functional change this results
in at the moment is having all Ethernet drivers returning the proper
errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown
ioctl's.
