enabled (from the attach routine), and add comments as to why.
Some PALcode apparently 'saves' a clock interrupt for the kernel,
and if the clock interrupt handler is enabled at attach time, it
will be run when that interrupt hits, i.e. right after the spl0()
at the end of autoconfiguration. That would cause hardclock to be
run, but proc0's p_stats isn't set up by then, which would cause
hardclock to crash.
rather than and-ing 16G-1. That just strips the k0seg bits, rather
than making the false assumption that the physical address is going
to be in the lower 16G. That doesn't apply for CIA device-space
addresses, for instance.
even if PCI and the IDs are right), just for sanity, before declaring
success. Split the single 0x3b0 -> 0x3df allocation into three seperate
ones: 0x3b0 -> 0x3bc (leaving the 4 ports available for lpt),
0x3c0 -> 0x3cf, and 0x3d0 -> 0x3df. The former chunk has to be split
off if the lpt can exist there, and it's sort-of pretty to have each
group (based on second hex digit) have its own handle.
ioctl and mmap routines take a void *, rather than a struct device *,
so that they can be set up to work more easily when using a 'struct device *'
isn't appropriate. Add a cookie (void *) to be passed to the mmap and
ioctl routines. Rename a few struct members, and shuffle them into
a more sensible order.
front-ends. Unfortunately, because of the way ISA and PCI are currently
probed, if you have a PCI VGA board in your machine and both drivers
in your kernel, the ISA VGA driver may accidentally match the PCI board.
For now, the only solution to this is to not put both drivers in
the GENERIC kernels.

is set in the RPB's rpb_variation field. This fixes a bug where machines
(e.g. the 3000/900) would see that they could touch memory where a built-in
PMAGB-BA, assume that it was there, and panic later because the memory they
were accessing didn't look like PMAGB-BA registers (because it wasn't).
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wcast-qual -Wno-format
(if not already set). -Wno-format is necessary because of the few
bits of code in the tree that use NetBSD's special kernel printf()
formats, and because there are a few bits of code that try to use the 'q'
modifier to print int64_t's (but int64_t's are only 'long' on the
alpha, not 'long long').
