MIPS: CMP/SMTC: Fix tc_id calculation
Currently the tc_id code is: (read_c0_tcbind() >> TCBIND_CURTC_SHIFT) & TCBIND_CURTC; After processing this becomes: (read_c0_tcbind() >> 21) & ((0xff) << 21) But it should be: (read_c0_tcbind() & ((0xff)<< 21)) >> 21 Signed-off-by: RongQing.Li <roy.qing.li@gmail.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/4077/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
