to 4 bytes free. I removed a printf (the Keyboard yes/no) since it is of
marginal value and sed'ed the generated asm output to remove the unwanted
aligns. There's probably a better way to gain a few extra bytes than
losing the printf. Shortening strings is probably a better option but this
should get us over the hurdle.
than the first one on a controller, and work for secondary
controllers.
Due to the prom not having nodes for each disk, but a catch-all one,
we have to iterate over each device, trying to open it to determine
whether it is actually present.
Since probing this way takese some time (and spews some spurious
warnings), it should maybe be short-circuited if we use the
device we were booted from.
Implement lazy device probing, and correct slice/partiniton
handling in the ofwd_open() code. With this, I can now actually boot
a kernel from disk, and the loader does not create unnecessary
delays.

a floating point instruction into a 6-bit register number for
double and quad arguments.
Make use of the new INSFPdq_RN macro where apporpriate; this
is required for correctly handling the "high" fp registers
(>= %f32).
Fix a number of bugs related to the handling of the high registers
which were caused by using __fpu_[gs]etreg() where __fpu_[gs]etreg64()
should be used (the former can only access the low, single-precision,
registers).

This is a temporary workaround so kernels work again on alpha.

This is said to fix the problem on some Compaq hardware (and perhaps

make sure it's a correct operation for devfs, do it only in the
ISLASTCN case. If we don't, we are assuming that the final file will
be in devfs, which is not true if another partition is mounted on top
of devfs or with special filenames (like /dev/net/../../foo).

- Axe -fdata-sections as turning it on or off makes no difference. If
it did make a difference it would serve to bloat boot2 even further with
extra padding.
- Axe -fforce-addr. This gets us 32 bytes so we are down to only being
64-bytes over.
We still can't compile this with gcc 3.1. The problem seems to be that
the -fno-align-foo options don't actually work. Comparing the new and
old output it turns out that gcc is 4-byte padding all the functions and
labels and what not despite the passed in arguments thus adding the
unfortunate bloat to boot2.
This code works by converting the Sun label to a struct disklabel, which
is probably even the right thing for reading a label. The original
checksum is taken over, so that the label source can be distinguished.
The NetBSD code to wrap a BSD-style disklabel into the Sun disklabel has been
deleted for now - don't know whether that is really desirable, after all Sun
disklabels could just be used always (BSD disklabels are going to have
problems with PROM compatability). The dsinit() call in diskopen() has been
#ifdef'ed out for now, this will be changed to use the minimal slice struct
in case of dsinit() failure.

Switch to USB_USE_SOFTINTR. The callout hack does indeed work
fine for systems without generic soft interrupts, even if it is
a little sub-optimal. Consider it a penalty for ports not
implementing a kernel API.
Addresses kern/11957. The PR has been open for 4 months, and
I have work blocked on the continued existence of splimp() in
the networking code.
The NetBSD patch only switches it on for NetBSD, but I've also
switched it on for FreeBSD in this commit.
