4b87c653f9 Properly wither the geom container on detach. This will allow one to 
then later reload fdc and not have duplicate fd devices in dev.

# Maybe this should be moved to a convenience function.

938eaf8e6b MFC amd64: 
Consolidate all of the bounce tests into the BUS_DMA_COULD_BOUNCE flag.
  Allocate the bounce zone at either tag creation or map creation to help
  avoid null-pointer derefs later on.  Track total pages per zone so that
  each zone can get a minimum allocation at tag creation time instead of
  being defeated by mis-behaving tags that suck up the max amount.

694f13aaff Stop building uart_dev_i8251.c. It was copied from uart_dev_ns8250.c 
without ever being changed to actually work with an i8251. Nobody is
working on this either at the moment, so it's not about to change
soon.
When the code necessary to support the i8251 is committed, this can
be reverted again.

4f5d62fbc6 o Remove the com_thr, com_rhr, com_isr and com_lctl defines. They are 
not used and aliases for other defines.
o  Add REG_DATA as an alias for com_data. Likewise for other register
   defines.
o  Add LCR_SBREAK and make CFCR_SBREAK an alias for it. Likewise for
   the other LCR register bits that are known with the CFCR prefix.
o  Add MCR_IE and make MCR_IENABLE an alias for it.
o  Add LSR_TEMT and make LSR_TSRE an alias for it.
o  Add LSR_THRE and make LSR_TXRDY as alias for it.

449835405d U areas are going away, so don't allocate them. It's worrisome that 
mp_machdep.c was using UAREA_PAGES to allocate something that isn't a
U area, and that there seems to be an implicit assumption that the PCB
is just past the end of the kernel stack.
