The function srmmu_pmd_clear() is optimized by the following line: BTFIXUPSET_CALL(pmd_clear, srmmu_pmd_clear, BTFIXUPCALL_SWAPO0G0); It's wrong, because srmmu_pmd_clear(pmd_t *pmdp) can contain up to 16 pmdp->pmdv pointers, which must be cleared, but BTFIXUPCALL_SWAPO0G0 clears only one of them. So, it's necessary to use BTFIXUPCALL_NORM instruction.
