MIPS: Hook up name_to_handle_at, open_by_handle_at and clock_adjtime …
Browse files Browse the repository at this point in the history
…syscalls.

These system calls we recently added.

32-bit ABIs need compat handling for sys_clock_adjtime().

o32 also needs compat handling for sys_open_by_handle_at();
