Modified Files:
        src/sys/arch/amd64/amd64: amd64_trap.S trap.c
        src/sys/arch/x86/x86: fpu.c

Log Message:
Change the argument to fpudna() to be the trapframe.
Move the checks for fpu traps in kernel into x86/fpu.c.
Remove the code from amd64/trap.c related to fpu traps (they've not gone
  there for ages - expect to panic in kernel mode).
In fpudna():
- Don't actually enable hardware interrupts unless we need to
  allow in IPIs.
- There is no point in enabling them when they are blocked in software
  (by splhigh()).
- Keep the splhigh() to avoid a load of the KASSERTS() firing.
