Another round of merge.
(1) Bug fix (pass boot drive):
pc98/boot/biosboot/boot2.S
(2) Delete code for unsupported high-resolution modes and move old
Epson notebook code to epsonio.h:
pc98/boot/biosboot/io.c
pc98/i386/vm_machdep.c
pc98/pc98/fd.c
pc98/pc98/pc98.c
pc98/pc98/pc98.h
pc98/pc98/epsonio.h (new)
(3) Change aic driver so that PCMCIA cards (I/O port same as PC/AT)
and PC-9801-100 cards can be selected with a flag in kernel config
file:
pc98/pc98/aic6360.c
pc98/pc98/aic_98.h (new)
(4) Fix wcd entry (it was broken). Delete mcd, it doesn't work on
98. Change aic entry according to above:
pc98/conf/GENERIC98
(5) Move pc98_machdep.c to top of files in pc98/pc98:
pc98/conf/files.pc98
(6) Delete empty lines:
pc98/i386/locore.s
(7) Fix (it didn't work if I586 was specified):
pc98/pc98/clock.c
(8) Staticize:
pc98/pc98/pc98_machdep.c
(9) Enable workaround for Cyrix bug for 5x86 also:
pc98/i386/machdep.c
pc98/i386/trap.c
All the above deletes this file too:
pc98/i386/pmap.c
(phew!)
