MIPS: Avoid pipeline stalls on some MIPS32R2 cores. The architecture specification says that an EHB instruction is needed to avoid a hazard when writing TLB entries. However, some cores do not have this hazard, and thus the EHB instruction causes a costly pipeline stall. Detect these cores and do not use the EHB instruction. Signed-off-by: Steven J.
