Does this really provide a measurable performance improvement?
Real hardware simply increments cp0_random together with the cycle
counter, this is randomized enough for TLB entry replacement.

Unfortunately, at least on my P4 PC it is not random enough: it is
always a multiple of two, so the number of TLBs is divided by two ! The
speed improvement is _very_ noticeable.
Your patch to accelerate tlb_flush_page() is still interesting, but I
would like to be sure that it does not reduce the speed of the x86
target. In particular, it could be possible to make it even faster by
reducing the size of the memset by using a smarter hash for tb_jmp_cache
(a few bit of the index could depend only on the memory page number).

As interim solution I moved it to mips specific code, I still don't
trust the MIPS TLB handling that much since it starts to fail once I
remove seemingly unnecessary flushes.
I still have nearly no time to work on qemu ATM. :-(
