- wrong name in .file statement.
- stale comment about CONSPEED.
- style bugs in comments.
- inconsistent defaulting of operand sizes (should never depend on default).
- inconsistent choosing between je and jz (should always use je).

The patch is for a Hauppauge Win/TV dbx with FM. I still need to
config OVERRIDE_TUNER, but it works nicely.
mlock, mmap, mprotect, msync, munlock, and munmap are defined by
POSIX as taking void *. The const modifier has been added to
mlock, munlock, and mprotect as the standard dictates.
minherit comes from OpenBSD and has been updated to conform with
their recent change to void *.
madvise and mincore are not defined by POSIX, but their arguments
have been modified to be consistent with the POSIX-defined functions.
mincore takes a const pointer, but madvise does not due to the
MADV_FREE case.
Discussed with: bde
the "READ_CAPACITY" command, rather than the physical blocksize
reported in the physical geometry code-page.
Also don't print out worrying bogus messages when probing a
device that has no media. There's no point in printing out
something that is unknowable. It just confuses things.
Move the check for valid blocksize out of 'open()' to the subroutine
that actually finds this out, thus probe/attach can also report and
act on the problem.
of vnodes and objects. There are some metadata performance improvements
that come along with this. There are also a few prototypes added when
the need is noticed. Changes include:
1) Cleaning up vref, vget.
2) Removal of the object cache.
3) Nuke vnode_pager_uncache and friends, because they aren't needed anymore.
4) Correct some missing LK_RETRY's in vn_lock.
5) Correct the page range in the code for msync.
Be gentle, and please give me feedback asap.
necessary to call it when the tty layer's output state has not been
changed, but siostop() sometimes changes the TS_BUSY state and then
calls comstart() mainly for its side effect of calling ttwwakeup().
need to do it directly, since ttwwakeup() is always called just before
returning from rpstart(). The brokenness was waking up the wrong address
after clearing TS_SO_OLOWAT. It's not clear how processes waiting for
output to drain below low water ever got woken up.
Found by: when I fixed longstanding warts in output watermark
handling, this was the only driver that knew too much
(anything) about the watermarks
for field widths being 2 larger than specified for "%<number>p". Only
printing of null pointers is "wrong" now (it is actually "right", but
inconsistent with printf(3)).
really used any features from <sys/malloc.h> since it was "blasted
from the past" in rev.1.15, and most .c files did not depend on
the namespace pollution (others have been fixed). The mbuf allocation
control values M_DONTWAIT and M_WAIT were just defined in terms of
the malloc control values M_NOWAIT and M_WAITOK. The mbuf values
are now defined directly.
here, but kmem_malloc() is used and it takes the same "flags" as
malloc().
Use the mbuf allocation "flags" M_WAIT and M_DONTWAIT consistently.
There is really only one boolean flag, M_DONTWAIT, but the "flags"
were always treated as enum-like values, except in some places here
where the values are tacitly converted to boolean flags. Treat
them as enum-like values everywhere, except where we tacitly assume
that there are only two values in order to convert them to the
corresponding two kmem_malloc() "flags".
used, and caused a reference to an uninitialised variable (state).
I think I've fixed it now, but since nothing in the tree seems to use it,
I'm not sure.
