-           The SH-5 FPU save/restore approach relies on last_task_used_math
-           pointing to a live task_struct.  When another task tries to use the
-           FPU for the 1st time, the FPUDIS trap handling (see
-           arch/sh64/kernel/fpu.c) will save the existing FPU state to the
-           FP regs field within last_task_used_math before re-loading the new
-           task's FPU state (or initialising it if the FPU has been used
-           before).  So if last_task_used_math is stale, and its page has already been
-           re-allocated for another use, the consequences are rather grim. Unless we
-           null it here, there is no other path through which it would get safely
-           nulled. */
