since it is not MD and not related to the lowest level of profiling.
It will be moved, but getting it via <sys/gmon.h> already works.

that's been called into question, so rather than argue about that (one
could make an excellent fair use argument), replace it with better
code since that's what FreeBSD is about.

[1] Bill called this a silly bikeshed. Maybe his is not incorrect.
and cannot handle it going away, add an explicit reference to the kobj
class inside each linker class. Without this, a class with no modules
loaded will sit with an idle refcount of 0. Loading and unloading
a module with it causes a 0->1->0 transition which frees the ops table
and causes subsequent loads using that class to explode. Normally, the
"kernel" module will remain forever loaded and prevent this happening, but
if you have more than one linker class active, only one owns the "kernel".
This finishes making modules work for kldload(8) on amd64.
(nobits) tables to simplify some code. Try and shorten some of the very
wide lines. Somewhere along the way, I think I fixed the memory
corruption that caused panics after going multiuser.

with the fifo.
Minor optimization of a couple of calls to fifo_cleanup() from
fifo_open().
reimplementations of enodev() (for the smbread() and smbwrite()
functions), as well as fixing various errno values to conform to
errno(3).
Bruce also points out that a number of the pointer == NULL tests
are probably nonsense because the respective checks are already
done at upper layers.

different context support for 32 vs 64 bit processes. This simply omits
the save/restore of the segment selector registers for non 32 bit
processes. This avoids the rdmsr/rwmsr juggling when restoring %gs
clobbers the kernel msr that holds the gsbase.
However, I suspect it might be better to conditionally do this at
user<->kernel transition where we wouldn't need to do the juggling in the
first place. Or have per-thread extended context save/restore hooks.
