- 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.

This fixes a dependency of mac_label.c on namespace pollution in
<vm/uma.h>.
Similarly for SYSCTL_DECL() although I had no problems with it. This
probably makes some includes of <sys/sysctl.h> bogus.
longer uses these interrupt vectors for its ISA interrupt pins, so these
entries will not be overwritten. If we get a spurious interrupt from the
ATPIC when using the APIC, it will be treated as a stray interrupt instead
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)
o returns anything it can't handle back to normal ip_input
Enable with sysctl -w net.inet.ip.fastforwarding=1

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.

- Move the IPI and local APIC interrupt vectors up into the 0xf0 - 0xff
range. The pmap lazyfix IPI was reordered down next to the TLB
shootdowns to avoid conflicting with the spurious interrupt vector.
- Move the base of APIC interrupts up 16 so that the first 16 APIC
interrupts do not overlap the vectors used by the ATPIC.
- Remove bogus interrupt vector reservations for LINT[01].
- Now that 0xc0 - 0xef are available, use them for device interrupts.
This increases the number of APIC device interrupts to 191.
- Increase the system-wide number of global interrupts to 191 to catch up
to more APIC interrupts.

the packets are immediately returned for sending (e.g. when bridging
or packet forwarding). There are more efficient ways to do this
but for now use the least intrusive approach.

in exit1(), make sure the p_klist is empty after sending NOTE_EXIT.
The process won't report fork() or execve() and won't be able to handle
NOTE_SIGNAL knotes anyway.
This fixes some race conditions with do_tdsignal() calling knote() while
the process is exiting.
