e0cc03a09b merge kqueue branch into -current 
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

848304f890 Fix bugs in the BIOS memory probe. 
- If the BIOS reports the same memory cluster multiple times,
  only allocate the extent once.

- If we fail to allocate an extent,
  don't add it to mem_clusters and don't increment mem_cluster_cnt.

- When loading the physical extents,
  make sure we don't try to add an extent with zero length (seg_start == tmp).

e57ba8d648 Introduce biosdiskreset(), and call it to reset the disk (with Int 
0x13 Function 0) after a read error. This is a requirement mentioned
in most BIOS documentation.

This answers PR 18591.

Incidentally, on the Soekris Engineering net45x1 single-board
computer, this fixes a bug where the bootloader corrupts the kernel
while loading it from certain varieties of CompactFlash card
(especially varieties identified by NetBSD as <TOSHIBA THNCF064MBA>).

ab7f74bdca Fix USER_LDT syscall locking. It's a bit over the top for a big lock 
kernel right now, a sleep lock around the entire thing would have
worked as well, but hey.

Also correct PCB_USER_LDT to PMF_USER_LDT. This was wrong but since
they had the same value, it didn't matter.

f493e906e6 Handle per-CPU local apic redir entries a little better. My previous 
solution relied on CPU entries coming first in the table, which
isn't guaranteed. Instead, export mp_intrs to lapic.c, and scan
it for entries that match the current CPU in lapic_set_lvt().

Also, do not try to up intr_cnt by the number of IO APICs or CPUs in
the case of MPS_ALL_APICS; it isn't needed, and it also relies on
CPU and IO APIC entries being earlier in the table.

14c70e4627 Put an unmapped page below the kernel stack (and above struct user) to 
catch kernel stack overflows. This bumps UPAGES from 2 to 4 (one unmapped),
because struct user take 1 page then there's the unmapped page, and
then the 2 pages for the kernel stack. If the NOREDZONE option is
set, UPAGES is 2 as before, and no unmapped page is used.

9110a093d8 Do rendezvous for TLB shootdown IPI. The sender sets a bitmask

in this mask.
