521871f1fa Turn of PG_PS and PG_G for Pentium-4 cpus at boot time. This is so
that we can stop turning off PG_G and PG_PS globally for releases.

1c425b874c Add a 'debug.witness_trace' sysctl (and tunable) when DDB is present.
This causes LOR and could-sleep messages to come with a stack trace.

8ebd558f5d Implement a handle for efficient implementation of perforations in
lower extremities.

Setting bit 4 in debugflags (sysctl kern.geom.debugflags=16) will
allow any open to succeed on rank#1 providers.  This will generally
correspond to the physical disk devices: ad0, da0, md0 etc.

This fundamentally violates the mechanics of GEOMs autoconfiguration,
and is only provided as a debugging facility, so obviously error
reports on GEOM where this bit is or has been set will not be
accepted.

22acd92b68 MF-p4:
Kill the slightly bogus #define for DECODE_PROTOTYPE
	Be less verbose.  Hide most (all I hope) of the CIS
	parsing behind cardbus_debug_cis (which is set with
	hw.cardbus.debug_cis=1).

	This doesn't fix problems with parsing, but should make cardbus
	less chatty.  There appears to be some issues still with the
	parsing of the CIS, but this won't fix them.

9476c349dd MFp4:
Second part of the kldload patches for cardbus.  This makes
	kldload of a driver for a device that's inserted now appears
	to work.  To make it work, we only do a power cycle of the card
	if there's no children drivers attached.

	This likely is papering over bogosities in the power system.  The
	power sequence needs to be re-written, so I'll not worry about
	the papering over until the re-write.

f0e185d705 Implement a bio-taskqueue to reduce number of context switches in
disk I/O processing.

        The intent is that the disk driver in its hardware interrupt
        routine will simply schedule the bio on the task queue with
        a routine to finish off whatever needs done.

        The g_up thread will then schedule this routine, the likely
        outcome of which is a biodone() which queues the bio on
        g_up's regular queue where it will be picked up and processed.

        Compared to the using the regular taskqueue, this saves one
        contextswitch.

Change our scheduling of the g_up and g_down queues to be water-tight,
at the cost of breaking the userland regression test-shims.

15c672a31d Make a mutex to stop the race coming into geom_disk's done routine.
Cut up requests into smaller bits if they are longer than the drivers
disk->d_maxsize or dev->si_iosize_max.

Properly handle the race condition when using g_clone_bio() is used
without having the single-threadedness of g_down/g_up secure locking.

The locking here needs to be revisited, but this ought to get rid of the

I or someone else interested with smp will eventually clear this up.
