Here is an analysis of the FPU problem:
1. Linux FPU emulation writes code on user stack
2. this code raises address error exception (caused by lw zero,1(zero))
more operations follow ...
3. Syscall 4119 (sigreturn) is written on user stack (same location as
above)
4. this code should raise syscal

This change still does not fix the problems with
self-modifying code in Linux FPU emulation.
Linux FPU emulation calls mips_dsemul which calls flush_cache_sigtramp
which is local_r4k_flush_cache_sigtramp for MIPS 4KEc. So I had expected
that the new code would fix the problems with FPU emulation.
