19288f738a Enable net.isr.enable by default, causing "delivery to completion" 
(direct dispatch) in interrupt threads when the netisr in question
isn't already active.  If a netisr is already active, or direct
dispatch is already in progress, we queue the packet for later
delivery.  Previously, this option was disabled by default.  I have
measured 20%+ performance improvements in IP packet forwarding with
this enabled.

Please report any problems ASAP, especially relating to stack depth or
out-of-order packet processing.

de78273e9c Document the implications of the callout_stop() returning 0 if the 
callout has finished or is in progress.  Also document that the
locking of the callout code for FreeBSD 5 has eliminated the 'or is in
progress' clause as a possibility and that such elimination is an
accident of the implementation and shouldn't be relied upon.

4e513b7a01 Allow the compiler to micro-optimize byte swapping functions by 
evaluating them at compile time rather than at run time.  As for x86
and amd64, this requires GCC and it's enabled only if __OPTIMIZE__ is
defined (ie, if at least -O is used).

6e478cc056 Introduce new __predict_false(exp) and __predict_true(exp) keywords. 
Their purpose is to give explicit hints to the compiler to judge
the likelyhood of a test to succeed or fail.  Not all architectures
have support for such optimizations, but for those who do, it can
give a nice performance improvement in hot loops.

Obviously, this should be used very rarely in very specific code.

ae0781a1cb Revert 1.24. It causes a hang on shutdown for Marcel. This is due to 
AcpiEnterSleepState() calling a long AcpiOsStall() with interrupts
disabled.  This fix will instead be added to ACPI-CA.

fa3f9daae5 - On my Pentium4-M laptop, invalpg takes ~1100 cycles if the page is found in 
the TLB and ~1600 if it is not.  Therefore, it is more effecient to
   invalidate the TLB after operations that use CMAP rather than before.
 - So that the tlb is invalidated prior to switching off of a processor, we
   must change the switchin functions to switchout functions.
 - Remove td_switchout from the thread and move it to the x86 pcb.
 - Move the code that calls switchout into swtch.s.  These changes make this
   optimization truely x86 specific.

b140bc1fc8 Correct pfil_run_hooks return handling: if the return value is non-zero 
then the mbuf has been consumed by a hook; otherwise beware of a null
mbuf return (gack).  In particular the bridge was doing the wrong thing.
While in the ipv6 code make it's handling of pfil_run_hooks identical
to netbsd.
