mips: fix mips_get_syscall_arg o32 check
commit c50cbd85 upstream. When checking for TIF_32BIT_REGS flag, mips_get_syscall_arg() should use the task specified as its argument instead of the current task. This potentially affects all syscall_get_arguments() users who specify tasks different from the current. Fixes: c0ff3c53 ("MIPS: Enable HAVE_ARCH_TRACEHOOK.") Signed-off-by: Dmitry V.
