From: Xing Li lixing@loongson.cn
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 in order to support variable ASID_MASK, KVM_ENTRYHI_ASID should also be changed to cpu_asid_mask(&boot_cpu_data).
