Subject: [PATCH v4 02/13] arm: nommu: use pgtable-nopud instead of 4level-fixup
Date: Tue, 5 Nov 2019 09:15:24 +0200
Message-ID: <1572938135-31886-3-git-send-email-rppt@kernel.org> (raw)
In-Reply-To: <1572938135-31886-1-git-send-email-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
The generic nommu implementation of page table manipulation takes care of
folding of the upper levels and does not require fixups.
Simply replace of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
