to take care of the KAME IPv6 code which needs ovbcopy() because NetBSD's
bcopy() doesn't handle overlap like ours.
Remove all implementations of ovbcopy().
Previously, bzero was a function pointer on i386, to save a jmp to
bzero_vector. Get rid of this microoptimization as it only confuses
things, adds machine-dependent code to an MD header, and doesn't really
save all that much.
This commit does not add my pagezero() / pagecopy() code.
Move the remaining bits of <sys/diskslice.h> to <i386/include/bootinfo.h>
Move i386/pc98 specific bits from <sys/reboot.h> to
<i386/include/bootinfo.h> as well.
Adjust includes in sys/boot accordingly.
if matchinstalled() found no packages, which happens to be the
case after fresh installations.
- Instead of using strstr(3) to match the package name, depend on
matchinstalled()'s MATCH_REGEX package matching.

actual address of buffer descriptor. This should fix the reported
calibration failures and subsequent speed problems with ich chipsets.
Minor calibration comment updates.
can do 64 bytes at a time and don't allocate lines in the L2 cache. These
assume that everything is 64 byte aligned, and that there's more than 128
bytes of data (best for whole pages). The block load and store instructions
don't follow normal memory ordering rules and require either a memory barrier
or move between registers before the data can actually be used. This
implementation correctly shuffles around 3 out of the 4 sets of registers
in order to avoid memory barriers expect for the last 2 blocks.
will be saved if we context switch as a result of an interrupt which occured
while using the floating point registers in the kernel (which actually can't
happen right now). This allows fp disabled traps in the kernel, which
normally shouldn't happen, so make sure the trapping code is what we expect
it is.
used to support block copy and zero operations in the kernel which use the
floating point registers.
- While I'm changing the size, improve the layout of struct pcb, sort by size,
then alphabetical etc.
- Add some assertions to validate assumptions made about how the pcb is
allocated.
for temporaries relating to the state of the new process instead of the
outs, so that functions can be called without fear of clobbering them.
- Use savefpctx instead of rolling our own.
