The patch titled mm: unify some pmd_*() functions fix has been removed from the -mm tree. Its filename was mm-unify-some-pmd_-functions-fix.patch This patch was dropped because it was folded into mm-unify-some-pmd_-functions.patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: unify some pmd_*() functions fix From: Andrea Righi <righi.andrea@xxxxxxxxx> Also unify implementations of pmd_*() functions in arch/*. This patch must be applied on top of mm-unify-some-pmd_-functions.patch.
