Subject: [patch 81/86] parisc: use pgtable-nopXd instead of 4level-fixup
Date: Wed, 04 Dec 2019 16:54:12 -0800
Message-ID: <20191205005412.QUSK_Z-Kb%akpm@linux-foundation.org> (raw)
In-Reply-To: <20191204164858.fe4ed8886e34ad9f3b34ea00@linux-foundation.org>

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: parisc: use pgtable-nopXd instead of 4level-fixup

parisc has two or three levels of page tables and can use appropriate
pgtable-nopXd and folding of the upper layers.

Replace usage of include/asm-generic/4level-fixup.h and explicit
definitions of __PAGETABLE_PxD_FOLDED in parisc with
include/asm-generic/pgtable-nopmd.h for two-level configurations and with
include/asm-generic/pgtable-nopud.h for three-lelve configurations and
adjust page table manipulation macros and functions accordingly.
