Add definitions for EntryLo register bits in mipsregs.h. The R4000 compatible ones are prefixed MIPS_ENTRYLO_ and the R3000 compatible ones are prefixed R3K_ENTRYLO_. These will be used in later patches. Signed-off-by: James Hogan <james.hogan@xxxxxxxxxx> Cc: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Cc: Maciej W.
