Subject: [PATCH] arm64/mm: Use CONT_PMD_SHIFT for ARM64_MEMSTART_SHIFT
Date: Mon, 14 Jun 2021 15:12:35 +0530 [thread overview]
Message-ID: <1623663755-8949-1-git-send-email-anshuman.khandual@arm.com> (raw)
ARM64_MEMSTART_SIZE needs to be aligned with CONT_PMD_SIZE on 16K page size
config. Hence just directly use CONT_PMD_SHIFT.
