The arch/mips/mips/fp.S file has not been updated for siginfo. I
believe this means it is possible for an unpriviledged user to induce a
kernel TLB miss on any MIPS CPU. Also, I think e_trapsignal should be
called by this code, not trapsignal directly.
I triggered this cancelling a ftp transfer on a softfloat machine,
possibly assisted by a different problem I am investigating.
I think the right thing to do would be to pass the info to a C function
in trap.c that sets up the ksi and calls e_trapsignal.
