e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight 
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page.  This could cause machine checks since the PTE after the last page
would not have the valid bit set.

(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)

35e9372060 Add entries to the intvid_info table that are equivalent to 
the (in)famous MADHATTER patch.  The only one that has been
tested is the Q700, however, so the rest are conditionalized
on the MADHATTER option until they can be verified.

3366b987d0 Put SGMAP-related stuff in the DMA map structure directly, rather than 
indirecting through a pointer.

2981fec2f0 Allow specification of a minimum page table alignment to alpha_sgmap_init(). 
This is to work around an apparent hardware bug in some 2117x chipsets
where the page table must be aligned to at least 32k.

now lives in dev/ic, wd now lives in dev/ata.  there's now a 'ata'

yet because some ports still use private versions based on the old
ISA version.

057795048f this is the i386 MD portion of the MACHINE_NEW_NONCONTIG code, as 
written by chuck cranor.  thanks to mycroft for helping me find the
one little line of code i accidentally deleted while merging it.

this is not enabled by default.  `options MACHINE_NEW_NONCONTIG'
will use this code.  eventually, this should go into <machine/vmparam.h>
insteaed of MACHINE_NONCONTIG.
