Subject: [PATCH v2 1/3] KVM: MIPS: Change KVM_ENTRYHI_ASID to cpu_asid_mask(&current_cpu_data)
Date: Mon, 13 Jan 2020 12:39:06 +0800	[thread overview]
Message-ID: <1578890348-2734-1-git-send-email-lixing@loongson.cn> (raw)

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)
for support 10bits ASID_MASK
