idle lwp, and some changes depending on it.
1. separate context switching and thread scheduling.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.

void _bus_dmatag_destroy(bus_dma_tag_t tag)
that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.
all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.
XXX: bus_dma(9) needs an update still.
by Slava Semushin <slava.semushin@gmail.com>.
To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".
Thanks to martin@ for the input on testing.
- finish implementing splraiseipl (and makeiplcookie).

- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
version.
Add disk_blocksize(9) so that disk drivers can record the physical
block size of a disk if it is different to DEV_BSIZE. Right now this
simply initialises dk_blkshift and dk_byteshift according to the
supplied block size. This information is used in the MI version of
bounds_check_with_label().
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.
This address kern/18407
children attaching and config(1) detects isa0 as orphaned in RC3230.
While turning isabus into an interface attribute doesn't work (because the
attribute 'isabus' already exists), depending on that very same attribute
works.
XXX I wonder what to allow, what to disallow. I'll think about it.
ones and those for specific machines of developers. PR 32304.
OK'ed by rpaulo.
N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
