Since pointer mask works on effective address, and the xl works on the

Incorrect. It has been done.
When updating the pm_mask, we have already considered the env->xl.
You can see it in riscv_cpu_update_mask
if (env->xl == MXL_RV32) {
env->cur_pmmask = mask & UINT32_MAX;
env->cur_pmbase = base & UINT32_MAX;
} else {
env->cur_pmmask = mask;
env->cur_pmbase = base;
}
Yeah, I missed this part. Then we should ensure cur_pmmask/base is updated when
xl changes.
Is that even possible? XL can change on priv level changes (SXL, UXL).
