Just noticed one more issue here, I think this will break these
two macros that now access four entries instead of two:

#define copy_pmd(pmdpd,pmdps)           \
        do {                            \
                pmdpd[0] = pmdps[0];    \
                pmdpd[1] = pmdps[1];    \
                flush_pmd_entry(pmdpd); \
        } while (0)

#define pmd_clear(pmdp)                 \
        do {                            \
                pmdp[0] = __pmd(0);     \
                pmdp[1] = __pmd(0);     \
                clean_pmd_entry(pmdp);  \
        } while (0)
