use COP0_HAZARD_FPUENABLE in a couple more places when turning on FP:
...
In start (noticed after looking for more COP_1_BIT uses, and note
that there are extra nops here but really they don't hurt), and in
MachFPTrap (noticed by ... running regress!).

no cache for the purposes of the cache setup code.

Add a realcode argument to trace_enter and ktrsyscall. realcode is the

original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

Add a hack to mipsNN_pdcache_wbinv_range_index_32_4way() so that we
...
use the index ops at a offset of the page size as well, controlled by
an MIPS64_SB1 check. The SB1 D-cache way size is physically indexed
and twice as big as the page size (4k), so we weren't flushing all the
addresses we needed too.
XXX: This is kinda gross; will be cleaned up and made more generic soon.
There are still other SB1-specific issues to be cleaned up too...
