commit 303be4b335 upstream.
When I do LTP test, LTP test case ksm06 caused panic at
break_ksm_pmd_entry
-> pmd_leaf (Huge page table but False)
-> pte_present (panic)
The reason is pmd_leaf() is not defined, So like commit 501b810467
("mips: mm: add p?d_leaf() definitions") add p?d_leaf() definition for
LoongArch.
Fixes: 09cfefb7fa ("LoongArch: Add memory management")
