riastradh 82de273b52 pax(9): Rework header file more coherently to nix some needless #ifs. 
Cleans up some of the fallout from PR kern/57711 fixes.

Could do a little more to nix PAX_SEGVGUARD conditionals but maybe
not worth it.

riastradh fddc6b2f61 ddb: New db_stack_trace_print_ra. 
Takes an optional extra argument for the return address so that the
stack parser has a chance to use instruction-dependent interpretation
of the frame to find parent frames.

Implemented only on Alpha for now, which needs it.  Other
architectures just ignore the extra argument.

thorpej 9c0baf1c81 pciide_dma_dmamap_setup(): If we end up with a DMA segment with an odd 
length or odd starting address, unload the map and return EINVAL.  Some
controllers get really upset if a DMA segment has an odd address or length.
This can happen if a physio user performs a virtually-contiguous I/O that
starts at an odd address and spans a page boundary where the resulting
physical pages are discontiguous.  The EINVAL return will cause the upper
layers in the ATA code to re-try the I/O using PIO, which should (will
in all of my tests) succeed.

if a DMA segment has an odd length.  This can happen if a physio user
performs a virtually-contiguous I/O that starts at an odd address and spans
a page boundary where the resulting physical pages are discontiguous.

Ultimately, it's up to the physio user to paint inside the lines, but this
will prevent the disk controller from wandering off into the weeds, at least.

Unfortunately, owing to PR kern/57705 and PR misc/57706, it isn't
convenient to flip the xfail switch on a test for this bug.  So we'll
do that separately.  (But I did verify that a rumpified version of
the test postd to PR kern/57703 failed without this change, and
passed with this change.)
