class, then it displays various information about the lock and calls a
new function pointer in lock_class (lc_ddb_show) to dump class-specific
information about the lock as well (such as the owner of a mutex or
xlock'ed sx lock). This is easier than staring at hex dumps of locks to
figure out who owns the lock, etc. Note that extending lock_class doesn't
affect the ABI for any kernel modules as the only code that deals with
lock_class structures directly is kern_mutex.c, kern_sx.c, and witness.

to disable the local APIC entirely and even Windows 64 doesn't boot on
it.

if the boot CPU has a local APIC because some BIOS vendors are not
competent enough to set this bit. Instead, just assume that we always have
a local APIC on amd64. For i386 the check is a bit more subtle. FreeBSD
requires either an MP Table or an ACPI MADT table to enumerate APICs. The
only systems that have one of those tables that don't have local APICs are
some presumably rare (and old) SMP 486 systems using external APICs. Thus,
instead of checking the CPUID_APIC flag, check the CPU class and abort if
we are running on a 486.

action argument with the value obtained from table lookup. The feature
is now applicable only to "pipe", "queue", "divert", "tee", "netgraph"
and "ngtee" rules.
An example usage:
ipfw pipe 1000 config bw 1000Kbyte/s
ipfw pipe 4000 config bw 4000Kbyte/s
ipfw table 1 add x.x.x.x 1000
ipfw table 1 add x.x.x.y 4000
ipfw pipe tablearg ip from table(1) to any
In the example above the rule will throw different packets to different pipes.
TODO:
- Support "skipto" action, but without searching all rules.
- Improve parser, so that it warns about bad rules. These are:
- "tablearg" argument to action, but no "table" in the rule. All
traffic will be blocked.
- "tablearg" argument to action, but "table" searches for entry with
a specific value. All traffic will be blocked.
- "tablearg" argument to action, and two "table" looks - for src and
for dst. The last lookup will match.
changes DELAY to use the TSC once it has been calibrated. This does NOT
use the TSC for long-term timekeeping. It only uses it to bound the
DELAY() spinloop. This should not be affected by the Athlon64 X2 TSC
quirks because the cpu is not halted while we use DELAY().
compilation of kernels without ns8250 support but using the uart framework.
These kernels will be for machines where size matters more, so including code
that can never be executed is undesriable...
this can happen under certain conditions when scanning. This logic
will eventually go away with the new scanning code.
While here de-inline the routine.

- Implement cv_wait_unlock() method which has semantics compatible
with the sv_wait() method in IRIX. For cv_wait_unlock(), the lock
must be held before entering the function, but is not held when the
function is exited.
- Implement the existing cv_wait() function in terms of cv_wait_unlock().
