From 40f87d3114b8a1e730ac8f3dc3cf1efe33124776 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Wed, 29 Jun 2016 14:51:30 +0200 Subject: [PATCH] arm64: mm: fold init_pgd() into __create_pgd_mapping() The routine __create_pgd_mapping() does nothing except calling init_pgd(), which has no other callers. So fold the latter into the former. Also, drop a comment that has gone stale.
