right now that are supposed to be atomic with respect to interrupts and
SMP: atomic_setbits_int and atomic_clearbits_int.
All architectures other than i386 and amd64 get dummy implementations
since at first we'll be replacing operations that are done with
"a |= bit" and "a &= ~bit" today. More proper implementations will follow

Shuffle. And other devices with no MBR, just a FAT32 filesystem.
Pointed out most recently by Stephan A. Rickauer for his sixth
generation, clip-on iPod shuffle.

- LK_EXCLUPGRADE is never used.
- LK_REENABLE is never used.
- LK_SETRECURSE is never used. Because of this, the lk_recurselevel
field is always zero, so it can be removed to.
- the spinlock version (and LK_SPIN) is never used, since it was decided
to use different locking structure for MP-safe protection.

cpu and if we do, send it an IPI that will force to get into the kernel
and process the AST.
This makes signals to processes on other CPUs to be actually delivered
as soon as possible instead of some time in the future when some
interupt happens.

should never be referenced outside the context of the process to which
this stack belongs unless we do the PHOLD/PRELE dance. Loads of code
doesn't follow the rules here. Instead of trying to track down all
offenders and fix this hairy situation, it makes much more sense
to not swap kernel stacks.

extended partition except on alpha, hppa, hppa64 and mips64. So don't
spoof extended partitions as 'a' and try to read a disklabel from
them. Make all archs consistant.
When we can boot from extended partitions we can change to reading and
writing disklabels from them.
This means the first OpenBSD ('A6') extended partition will now be
ignored during spoofing, just as subsequent ones have always been.

partitions with 0 in the length field we don't need to test for
and skip partitions that are all zeros. Eliminating that code
allows elimination of a local pointer.
