From: Ard Biesheuvel Date: Wed, 29 Jun 2016 12:51:30 +0000 (+0200) Subject: arm64: mm: fold init_pgd() into __create_pgd_mapping() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=40f87d3114b8a1e730ac8f3dc3cf1efe33124776;p=openwrt%2Fstaging%2Fblogic.git 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.
