Subject: MIPS: syscall: Fix AUDIT value for O32 processes on MIPS64
From: Markos Chandras <markos.chandras@xxxxxxxxxx>
commit 40381529f84c4cda3bd2d20cab6a707508856b21 upstream.
On MIPS64, O32 processes set both TIF_32BIT_ADDR and
TIF_32BIT_REGS so the previous condition treated O32 applications
as N32 when evaluating seccomp filters. Fix the condition to check
both TIF_32BIT_{REGS, ADDR} for the N32 AUDIT flag.
