have no drivers.
Standby TIMER that we don't use. One of the timers is always out of
standby on my Jornada on boot (WinCE uses it), so save some power.
Standby AFE and FIR for which we have no drivers (I don't know if any
hpcsh hardware actually uses them, so they are likely to be in standby
already anyway).
Fix numerous problems:
1. LDT updates are not atomic.
2. Number of processes running with private LDTs and/or I/O bitmaps
is not capped. System with high maxprocs can be paniced.
3. LDTR can be leaked over context switch.
4. GDT slot allocations can race, giving the same LDT slot to two procs.
5. Incomplete interrupt/trap frames can be stacked.
6. In some rare cases segment faults are not handled correctly.
attach pcmcia devices before interrupts are enabled. This is unclean
because pcmcia drivers use tsleep(9) in the attach code path but it
worked all the time and it is too late to change this on the 5.0 branch.
So just tolerate it.
Fixes a regression on hpcsh reported by Valeriy E. Ushakov.

Note on old 8169 chips IP hw csum must be enabled to use TCP/UDP hw csums,
but I'm not sure if these newer chips still have the same restriction.
some reason. Restore it to correct 16.
HTF did hpcsh work all this time with hd6446x_imask[_IPL_N] indexed
with IPLs 0..15 is a mistery... Discovered by accidentally triggering
hd64461 timer interrupt that is not enabled and should have been
masked.
_IPL_N used to be *also incorrect* 15 before Andy's change, which
makes one wonder if dumb luck is severly underappreciated.
easier to do it there rather than mess with config_interrupts()).
From kiyohara@. Discussed with drochner@, who pointed out that pcmcia
drivers are expected to attach with interrupts enabled.
we don't have. Replace ".Dd $Mdocdate" with ".Dd Month Day Year" so
that the date comes out right when man pages get built. This will
doubtless need hand conflict resolution whenever these pages are
re-imported.
Note that it would be interesting to have some similar facility for
NetBSD, but I don't think a custom rcs keyword is the right thing --
maybe we can teach groff to parse $Date$
executable. Remove this so that different compiles can be binary
compared. rcsid's for all files are already embedded in the executable
so versions can be easily distinguished. (I didn't catch this on
previous passes because I did my builds on the same day.)
Note: there's a special rule for main.o in Makefile with a purpose I
can't actually discern -- I think it isn't needed, and I've flagged it
with a comment.
so check for a non-NULL configuration descriptor before dereferencing.
Should fix a crash reported by Nicolas Joly per PR kern/41048.
(It still doesn't look good that the ioctl which unconfigures the device
returns EIO -- either it is legitimate or it isn't -- but since this
is a pullup candidate I don't dare to change user visible behaviour.)
