1e35598c3a Deregister the dev_clone event handler when unloading the module. Bad 
things might happen otherwise.

00ad14c702 Improve a comment and undo a bogus s/a/an/ in a comment. An asm guru 
should add more comments explaining which registers hold which variables.

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.

8a63edc3a1 Better names for struct disk elements: d_maxsize, d_stripeoffset 
and d_stripesisze;

Introduce si_stripesize and si_stripeoffset in struct cdev so we
can make the visible to clustering code.

Add stripesize and stripeoffset to providers.

DTRT with stripesize and stripeoffset in various places in GEOM.

42e1b74af2 Don't lock FILEDESC under PROC. 
The locking here needs to be revisited, but this ought to get rid of the
LOR messages that people are complaining about for now.  I imagine either
I or someone else interested with smp will eventually clear this up.

9ca938eb11 Don't turn off the power of cards when new drivers are added 
unconditionally.  kldloading a cardbus driver was shooting down other
attached devices because most drivers assume that one cannot
power-cycle cards w/o the driver knowning about it.

407b015791 - Add a new variable 'kg_runtime' that tracks the amount of time we've run. 
- Use the ratio of kg_runtime / kg_slptime to determine our dynamic priority.
 - Scale kg_runtime and kg_slptime back when the sum of the two exceeds
   SCHED_SLP_RUN_MAX.  This allows us to slowly forget old behavior.
 - Scale back the runtime and slptime in fork so that the new process has the
   same ratio but much less accumulated time.  This causes new behavior to be
   noticed more quickly.

ffb37f33f8 Implement a new dynamic command allocator. FIBs are allocated in 1 page 
blocks now, which should eliminate problems with the driver failing to
attach due to insufficient contiguous RAM.  Allow the FIB pool to grow
from the default of 128 to the max of 512 as demand grows.  Also pad the
adapter init struct to work around the 2120/2200 DMA bug now that there
is no longer a FIB slab.

800 nsec per consumer/provider set on a 700MHz Athlon.
