Module Name:    src
Committed By:   drochner

Modified Files:
        src/sys/arch/mips/conf: files.mips

Added Files:
        src/sys/arch/mips/mips: mips_fputrap.c

Log Message:
fix some problems with FPU exception signaling:
-The MachFPTrap did generate pre-siginfo arguments to trapsignal(),
 leading to an immediate crash.
 Put the siginfo generation into a separate .c file for simplicity.
-The exception bits in MIPS_FPU_CSR didn't get cleared, leading to
 trouble later ("kernel used FPU" on pmax).
 XXX This should probably be done for the "unimplemented fpu instruction"
  case as well, but I don't know how to test this. Or, even better -
  centralize the CSR clearing before the branch in MachFPTrap.
