UltraSPARC-IV CPUs seem to be affected by a not publicly documented
erratum causing them to trigger stray vector interrupts accompanied by a
state in which they even fault on locked TLB entries. Just retrying the
instruction in that case gets the CPU back on track though. OpenSolaris
also just ignores a certain number of stray vector interrupts.
While at it, implement the stray vector interrupt handling for SPARC64-VI
which use these for indicating uncorrectable errors in interrupt packets.
