Subject: [PATCH] MIPS: Change KVM_ENTRYHI_ASID to cpu_asid_mask(&current_cpu_data)
Date:   Sat, 26 Oct 2019 17:39:04 +0800
Message-Id: <1572082744-15586-1-git-send-email-lixing@loongson.cn>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The code in decode_config4 of arch/mips/kernel/cpu-probe.c

        asid_mask = MIPS_ENTRYHI_ASID;
        if (config4 & MIPS_CONF4_AE)
                asid_mask |= MIPS_ENTRYHI_ASIDX;
        set_cpu_asid_mask(c, asid_mask);

set asid_mask to cpuinfo->asid_mask

So KVM_ENTRYHI_ASID should change to cpu_asid_mask(&current_cpu_data).
