- softclock was called with extra argument.
- missing %x formats in printf's
- kgdb_copy called with only two arguments.
Fix conf.c so that it used the _conf.h files from other places instead of
rolling its own.
[these bugs apply to the xy as well as the xd driver]
[1] check return value from malloc() for NULL before trying to bzero it.
[2] use "=" rather than "|=" when writing to CSR (otherwise you may
ACK something you don't mean to!).

of bwtwo, cgfour, cgsix, and cgeight. Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).
P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.
This code may still need polishing.
Apparently, some early 4/100 DMA controllers do illegal memory access on
large ( >= NBPG ) transfers at the end of the transfer. This appears
as SI_CSR_DMA_BUS_ERR in the csr. To work around this, we simply
transfer the (up to 3) missing bytes from the bpr. We were doing this
anyway, so the work-around is to ignore the bus error.
BUT! I goofed when I implemented the "left-over byte" code for the sw!
It *should* be correct now. Keep metrics (acceeible via DDB) on the number
of 1, 2, and 3 byte clean-ups, as well as the number of "clean" transfers,
just so we can get a clearer picture.
Thanks to Andrew Gillham <gillham@whirlpool.com> for noticing this!
only get these during autoconfiguration and during crash dumps. During
autoconfiguration, the transfers are small enough that DVMA won't be used
anyway. However, using DVMA during a crash dump can be dangerous,
depending on the nature of the panic, so we avoid it.
