cpuid with %eax=1 will return a logical cpu count in bits 16-23 of %ebx.
Bit 29 is actually 'TM' according to AP-485. This signifies the presence
of the thermal control circuit (which I believe can slow the clock down
to reduce core temperature).
they make it through to userland. This should fix the p5-smp problem
without affecting the other cpus (eg: cyrix, see initcpu.c and the special
cache handling for these cpu types).
o Remove bogus flags that aren't used (if we need them in the future, we can
add them back).
o Add support for the TI-1031. This is the only YENTA compatible PCI-PCMCIA
bridge that I'm aware of (all the others are PCIC on a PCI bus, which is
different).
not return ENOBUFS for unreliable protocols like divert.
This should fix an issue when natd(8) keeps spamming already
full dummynet(4) queues with the same packet forever.

seem to be too short for the 500 Mhz DS20 I'm testing on. The rather
arbitrary numbers are rather bogus anyways. We should probably have
variables for these limits that are calibrated in the MD startup code
somehow.
NULL rather than curproc. Without this, if we trap early before
curthread is set, we recursively panic.
- In an SMP kernel, if we trap before curthread is set, then trap is going
to recursively panic trying to bump td->td_md.md_kernnest. The trap is
fatal anyways, so to make debugging easier just call printtrap() to
dump the trap info to the console and then halt.
The catpaging and setuidness features of man(1) combined make
it vulnerable to a number of security attacks. Specifically,
it was possible to overwrite system catpages with arbitrarily
contents by either setting up a symlink to a directory holding
system catpages, or by writing custom -mdoc or -man groff(1)
macro packages and setting up GROFF_TMAC_PATH in environment
to point to them. (See PR below for details).
This means man(1) can no longer create system catpages on a
regular user's behalf. (It is still able to if the user has
write permissions to the directory holding catpages, e.g.,
user's own manpages, or if the running user is ``root''.)
To create and install catpages during ``make world'', please
set MANBUILDCAT=YES in /etc/make.conf. To rebuild catpages
on a weekly basis, please set weekly_catman_enable="YES" in
/etc/periodic.conf.

involving file removal or file update were not always being fully
committed to disk. The result was lost files or corrupted file data.
This change ensures that the filesystem is properly synced to disk
before the filesystem is down-graded.
This delta also fixes a long standing bug in which a file open for
reading has been unlinked. When the last open reference to the file
is closed, the inode is reclaimed by the filesystem. Previously,
if the filesystem had been down-graded to read-only, the inode could
not be reclaimed, and thus was lost and had to be later recovered
by fsck. With this change, such files are found at the time of the
down-grade. Normally they will result in the filesystem down-grade
failing with `device busy'. If a forcible down-grade is done, then
the affected files will be revoked causing the inode to be released
and the open file descriptors to begin failing on attempts to read.

Introduce a new poll op "POLLINIGNEOF" that can be used to ignore
EOF on a fifo, POLLIN/POLLRDNORM is converted to POLLINIGNEOF within
the FIFO implementation to effect the correct behavior.
This should allow one to view a fifo pretty much as a data source
rather than worry about connections coming and going.
