Log message:
On Loongson 2 processors, clear the branch target buffer on userland->kernel
transitions, to work around an evil horde of evil bugs in the processor's
branch prediction logic.
This finally makes the Lemote Yeeloong stable, and I can now spend my
time looking for hair implants resellers.
