 - Change FPCPU_LOCK() such that the caller is responsible for blocking
   IPIs in the MULTIPROCESSOR case.  Adjust all callers.
 - In fpusave_cpu(), block IPIs for the entire duration (while we have
   CPUF_FPUSAVE set in ci_flags) to fix the deadlock that leads to
   "panic: fpsave ipi didn't", as described in PR port-alpha/26383.
   Many thanks to Michael Hitch for the analysis and initial patch which
   this one is derived from.
