The parse_early_param() calls param callbacks in variety of subsystems including MM. Doing init_mm setup before parse_early_param() ensures that initial MM state is available when MM param callbacks are called. My intention was mainly to make boot-up flow similar to x86, ARM and ARM64 so that it is easy to add features already present in these arch ports. Regards, Anup
