landisk, and the sparc implementation is obviously wrong. That's where I
stopped looking, so who knows what else was broken. A simple comparison of
the existing mtx_enter with the new mtx_enter_try would have told anybody.

Saves every damned driver calling bzero(), and continues the M_ZERO,
PR_ZERO symmetry.

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.

levels. This will allow for platforms where soft interrupt levels do not
map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

try to be smart for the address range, uvm_pglistalloc() is smart enough
nowadays.

as additional argument. This will allow intermediate layers between
scsi devices such as sd and scsi host adapters to take appropriate
action if necessary.

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@.

they are no longer necessary. No good reason to do so but correctness, and
then leaving correct mappings after probe might hide bugs.

which are uniform for the profclock on each cpu in a SMP system (but using
a different seed for each cpu). on all cpus, avoid seeding with a value out
of the [0, 2^31-1] range (since that is not stable)

This should take care of the simpler ones (i.e., timeout values of

anything special to prod a cpu to leave the idle loop in signotify.
powerpc, i386, amd64 and sparc64 will follow soon so that everyone has
the same interface to wake an idling cpu.

For now, sparc64 is arbitrarily set to 256 (only architecture that didn't have
a practical limit in the code on the number of cpus).

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.
