[PATCH] MIPS: Hook up sys_name_to_handle_at, sys_open_by_handle_at and sys_clock_adjtime.

[PATCH] MIPS: Hook up sys_name_to_handle_at, sys_open_by_handle_at and sys_clock_adjtime.

[David Daney]

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();
