Subject: [PATCH V2 1/2] powerpc/mm: Drop platform defined pmd_mknotpresent()
Date: Wed, 22 Apr 2020 07:22:05 +0530 [thread overview]
Message-ID: <1587520326-10099-2-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1587520326-10099-1-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.
