Subject: [PATCH 1/2] powerpc/mm: Drop platform defined pmd_mknotpresent()
Date: Fri, 20 Mar 2020 10:24:16 +0530 [thread overview]
Message-ID: <1584680057-13753-2-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1584680057-13753-1-git-send-email-anshuman.khandual@arm.com>
Platform needs to define pmd_mknotpresent() for generic pmdp_invalidate()
only when __HAVE_ARCH_PMDP_INVALIDATE is not subscribed. Otherwise platform
specific pmd_mknotpresent() is not required. Hence just drop it.
