8617f2c7f5 Simplify the SGMAP code a bit, and move SGVA allocation out of a
common routine into the individual load routines, since each load
routine needs to muddle with the "internals" of this operation.

Add a `prefetch threshold' member to the bus_dma_tag_t, so that
eventually we can determine whether or not to allocate a spill
page on a per-mapping basis.

db36913c87 The code that creates/destroys SGMAP DMA maps is the same; put it
in a common place and share it.

579eeb8cf7 If we have to increase the boundary due to the spill pages, use the old
boundary as an alignment.  Otherwise we fail to enforce the old boundary,
causing massive lossage.

4ccb969d0b Okay, handle the ALLOCNOW case by doing the appropriate adjustments
up front. Do the spacing arithmetic slightly differently.

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...)

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.

693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.
