+       - 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.
