value as reserved for internal use in boot blocks, because RB_PAUSE
broke binary compatibility by usurping the RB_DUAL flag. Probably no
one except me has boot blocks for which this matters, since most boot
blocks based on biosboot including pc98's boot2 can't boot elf kernels,
and /boot/loader doesn't properly pass flags set by the previous stage.
reboot.h:
Also mark the historical RB_PROBEKBD flag (0x80000) as reserved for
internal use in boot blocks.

Added comments to inhibit usurping of other flags.

kses from the run queues. Also, on SMP, we track the transferable
count here. Threads are transferable only as long as they are on the
run queue.
- Previously, we adjusted our load balancing based on the transferable count
minus the number of actual cpus. This was done to account for the threads
which were likely to be running. All of this logic is simpler now that
transferable accounts for only those threads which can actually be taken.
Updated various places in sched_add() and kseq_balance() to account for
this.
- Rename kseq_{add,rem} to kseq_load_{add,rem} to reflect what they're
really doing. The load is accounted for seperately from the runq because
the load is accounted for even as the thread is running.
- Fix a bug in sched_class() where we weren't properly using the PRI_BASE()
version of the kg_pri_class.
- Add a large comment that describes the impact of a seemingly simple
conditional in sched_add().
- Also in sched_add() check the transferable count and KSE_CAN_MIGRATE()
prior to checking kseq_idle. This reduces the frequency of access for
kseq_idle which is a shared resource.

Fixed some style bugs in macros:
- not splitting the line when the macro value cannot be lined up in much
the same macros that didn't parenthesize their args
- braces around a 1-line statement
- do-while(0) hack not indented in the usual way in the same macros that
defeated its point.

mac_prepare_type() may now be directly employed by a user process,
push the check and initialization into that function.

- For acpi_pci_link_entry_dump(), add a few helper functions to display
the trigger mode, polarity, and sharemode of an individual IRQ resource.
These functions are then called for both regular and extended IRQ
resources.
- In acpi_pci_link_set_irq(), use the same type of IRQ resource
(regular vs. extended) for the new current resource as the type of
the resources from _PRS.
- When routing an interrupt don't ignore extended IRQ resources. Also,
use the same type of IRQ resource (regular vs. extended) for the new
current resource when as the type of the resource from _PRS.

Similarly for SYSCTL_DECL() although I had no problems with it. This

of causing a panic.
Short description of ip_fastforward:
o adds full direct process-to-completion IPv4 forwarding code
o handles ip fragmentation incl. hw support (ip_flow did not)
o sends icmp needfrag to source if DF is set (ip_flow did not)
o supports ipfw and ipfilter (ip_flow did not)
o supports divert, ipfw fwd and ipfilter nat (ip_flow did not)

The gre(4) driver does not use INET6, nor is it specified for IPv6. The
tunnel_status() function in ifconfig(8) is somewhat overzealous and assumes
that all tunnel interfaces speak KAME ifioctls.
This fix follows the path of least resistance, by teaching gre(4) about
the two KAME ifioctls concerned.
