defined, then #error out. This is protected inside of #ifdef _KERNEL.
This allows one to tag code in the tree that will be deleted in 6.x
with the 'OBSOLETE_IN_6 #define at the top of the file. This makes
for easy grepping, plus a mechanism that automatically fails the
compilation of those files that are so tagged after we do the cutover.
However, GENERIC has wdc commented out, and COMPAT_OLDISA is required
for that. Comment out COMPAT_OLDISA and sdd a comment to this effect
near wdc.

o Register ISR INTR_MPSAFE.
o Loop on KTHREAD_DONE == 0 in the thread.
o Safe the INTR_MPSAFE flag for client drivers (don't know if there are any
CardBus/PCI drivers that are INTR_MPSAFE)
o Read status after acquiring mtx_lock(Giant) rather than before so that we
catch state changes that happen while Giant is being acquired.
o Turn off the CD bit when we see a CD interrupt, and turn it back on after
we've attached/detached the card.
o On suspend, actually set the CBB_SOCKET_MASK to zero rather than oring
in '0' to turn it off on suspend.
o If the ISR that's registerd is MPSAFE, don't acquire Giant around call to
client ISR.
o Fix comments to reflect these changes.
PCB contains FP registers, whose alignment must be 16 bytes at least.
Since the PCB pointed to by pc_pcb is immediately after the PCPU
itself, round-up the size of thge PCPU to a multiple of 16 bytes. The
PCPU is page aligned.
This fixes a misalignment trap caused by stopping a CPU in a SMP
kernel, such as been done when entering the debugger.

number X, rather than mdX, making it easier to script tests that
use md devices but don't want to make assumptions about any existing
md use (such as in diskless environments).
too small panics on PAE machines which have odd > 4GB sizes (4.5 gig
would render a 20MB of KVA for kmem_map instead of 200MB).
