As message in commit 7df676974359 ("mm/memory.c: Update local TLB
if PTE entry exists") said, we should update local TLB only on the
second thread. So fix the misuse of update_mmu_cache() by using
update_mmu_tlb() in the do_anonymous_page().

The change looks good to me. However, I am not sure what is the
user-visible
effect to xtensa users. So Cc xtensa’s maintainer and the author of
7df676974359
to double check this.
And if there is one, do we have a fixes tag?
IIUC, there's only a performance difference here, so maybe there's no
need to add the fixes tag?
Maybe be careful with the usage of "fix" in subject/description then and
point that out in the description :)
Ah, will change subject/description in the v2, thanks. :)
