Reintroduce bufqs. A few changes since it was backed out after some good
comments from dlg@.
No need for a separate bufq.h, keep all of in buf.h; As requested by kittens
and deraadt.
Only sd(4) and wd(4) for now. The rest of the drivers will be converted soon,
also other goodies like heuristics for sd(4) for selecting the bufq type and
the death of disksort() are forthcoming.
Tested on: i386, amd64, sparc64, macppc, loongson and alpha by myself and
phessler.

We cannot yet get at vax/subr.s via files.vax because rdsetroot doesn't
like it when the "start" symbol isn't in the first page of the executable.
subr.s will have to be merged into locore.S later on, when other problems
with ENTRY() are solved (says Miod)

Don't set SDEAD on the process in exit1 untile we have grabbed the
allproclk. allproclk is a rwlock and thus we may sleep to grab hold of
it. This is a big of a bugger when we just set a flag that means we
panic if we sleep.
ok art@. turns Tom Murphy's fstat panic into a deadlock instead *sigh*,
this is being looked into.

at least one hyphen, we already had support for breaking the line a the
last fitting hyphen. This patch improves this functionality by only
breaking at hyphens in free-form text, and by not breaking at hyphens
* at the beginning or end of a word or
* immediately preceded or followed by another hyphen or
* escaped by a preceding backslash.
Before this patch, differences in break-at-hyphen support were one
of the major sources of noise in automatic comparisons to mdoc(7)
groff output. Now, the remaining differences are hard to find among
the noise coming from other sources.
Where there are still differences, what we do seems to be better than
what groff does, see e.g. the chio(1) exchange and position commands
for one of the now rare examples.

Besides, this was the last substantial code difference left
between bsd.lv and openbsd.org. We are now in full sync.

Also make sure not to take the scheduler lock once we have stopped a CPU such
that we can safely take it away without having to worry about deadlock
because it happened to own the scheduler lock.
Fixes issues with suspen on SMP machines.

Explain how an invaviant is satisfied and add an assertion to check
(never hit that one). As a side benefit clang doesn't bitch about a
possible NULL deref now.

that in the reading-only case we need only wait for all gpu writes to be
done and flushed), don't then wait for the full seqno anyway.
Found by Clang's static analyser where it flagged a dead store to the
seqno variable.

the differences between these files. You will need a newer config(8) binary
to be able to build kernels.

line with everything in the tree. No functional change.
I have wanted to do this for ages! More cleanup will be forthcoming.
|
|
We no longer support these paths, only memory managed mode is now allowed.
|

add a missing ')'.
i386 can now build kernels.

correct number of bytes into f_fstr. OK kettenis@ deraadt@ nicm@

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.
Idea from a discussion with drahn

functions a bit to make them all look more similar. All but the label req
abort message are now parsed and passed to the lde.
|
|
Add missing bits to struct map and restructure/simplify the lde.c imsg
code.
|
|
That function will be needed soon.

full-duplex, we may detect a xrun in the play direction and discard
the clock tick, this would cause sio_revents() to return POLLIN
without the clock being advanced, causing apps relying on the clock
for flow control to enter a busy loop.

|
use this format instead of the non-extended one (ex. audio/libao)
