b65bdb63d6 Add an EXTMEM_SIZE option to set the size of extended memory on systems

18ec26aa21 add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH, 
execpt without quotes.  meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).

fedca4f133 Attach isa, eisa, and pci to mainbus now, rather than root. The i386 
now has a single device tree (rather than a forest).  Also, attach
EISA only if it's present, and attach in order: PCI, EISA, ISA (most
specific to least specific).

440b3cbc94 update for new EISA autoconfiguration: there can now be an eisa0 at root, 
and ahb attaches to eisa, not isa.  Also, ahb* at eisa?... is now supported,

d586688437 In fdcretry(), set the state to DOSEEK rather than SEEKCOMPLETE before 
retrying the operation.  Fixes disk_unbusy() imbalance and really seems
like the right thing to do in case it was the seek that failed.  Takes
care of PR #1985.  Patch from John F. Woods <jfw@jfwhome.funhouse.com>
