seen in practice. The MPspec is ambiguous and/or contradicts itself.
We now look at the ELCR to determine the trigger mode (edge/level) of an
interrupt tagged as "conforming" in the mptable. EISA interrupts appear
to be presented to the APIC as active high in all cases (they are level
inverted) that we've seen, so use this for the 'conforming' level case.
Of note, the system I'm using has 2 PCI cards in it, and the PCI cards
interrupts (5 and 9) appear in the ELCR register as level sensitive and the
mptable lists 5 and 9 as coming from the EISA bus. The PCI interrupts
are active-high by the time they reach the APIC even though they are
electrically active low at the slot.
We should still work should somebody implement this on motherboards
differently in the future as long as the mptable is clear about the
trigger/polarity.
Current should work on Holm Tiffe's machine now.
Based on code from: Tor.Egge@fast.no
here for getting the #defines for the removal of the leading '_' in symbols
in the assembler code. We could probably #include <machine/asnames.h>
instead, but everything else seems to use asmacros.h directly as well.
Once we convert symbols, this becomes irrelevant.
fix the 50% idle problem that the ELF /sbin/init triggered. The problem
appeared when the last context switch before a fork() call was due to
the kernel faulting in user pages via normal page faults (e.g. copyin).

certainly change in the future.
While I'm here, finish off the shared library brouhaha with miniperl.
syncs weren't optimized properly (they probably still aren't, but are bug
for bug compatible with ffs). These fixes are mostly academic, since
ext2fs is too broken to mount read-write (it apparently doesn't clear
indirect blocks).

minor number bump, but otherwise the current functionality of libdialog
is unchanged (in all its evil glory) and the change is non-intrusive.

Fixes for bugs not shared with ffs:
- don't mount unclean filesystems rw unless forced to.
- accept EXT2_ERROR_FS (treat it like !EXT2_VALID_FS). We still don't set
this or honour the maximal mount count.
- don't attempt to print the name of the mount point when mounting an
unclean file system, since the name of the previous mount point is
unknown and the name of the current mount point is still "".
Fixes for bugs shared with ffs until recently:
- don't set the clean flag on unmount of an initially-unclean filesystem
that was (forcibly) mounted rw.
- set the clean flag on rw -> ro update of a mounted initially-clean
filesystem.
- fixed some style bugs (mostly long lines).
The fixes are slightly simpler than for ffs, because the relevant on-disk
state is not a simple boolean variable, and the superblock has a core-only
extension.

This uses the fs_flags field and FS_UNCLEAN state bit which were
introduced in the softdep changes. NetBSD uses extra state bits in
fs_clean.
