        src/sys/arch/m68k/m68k: fpu.c switch_subr.s

Log Message:
Eliminate the (multiple) conditional branches based on fputype in the
m68k context switch path.  Instead, the FPU save and restore blocks
begin with a BRA.W insn that branches around the FPU code, essentially
refleching FPU_NONE.  Once the FPU is probed, these BRA.W insns are
patched with the displacement for the correct code fragment for the
detected FPU.
