977 Please make sure to pick the right CPU type. Linux/MIPS is not
978 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
979 *not* work on R4000 machines and vice versa. However, since most
980 of the supported machines have an R4000 (or similar) CPU, R4x00
981 might be a safe bet. If the resulting kernel does not work,
982 try to recompile with R3000.

1407 controller management code, SMTC has a "backstop" to track and
1408 if necessary restore the interrupt mask. This has some performance
1409 impact on interrupt service overhead. Disable it only if you know
