[RFC PATCH v2 00/22] target/mips: Reintroduce the R5900 CPU (without testing)

[Philippe Mathieu-Daudé]

First part (TCG, testing postponed) of RFC v1:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg782449.html

3 patches can still be improved for performance, but the improvement
is not yet addressed in this series. Other patches are good enough
for review.
