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.
But programs like aptitude crash (caused by FPU emulation)
even with latest QEMU CVS.

Indeed, it fixes gdb breakpoints, though. (Which means I believe by
now Paul was right with his analysis of the FPU problem.)

I think Daniel also mentioned how to fix breakpoints properly.

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 syscall exception, but raises address error
exception
Step 4 is wrong: QEMU logs the correct code, but executes code from step 2.
See extract from qemu.log below. It was modified to log tlb_flush_page, too.
