From: Anshuman Khandual <anshuman.khandual@xxxxxxx>
Subject: powerpc/mm: drop platform defined pmd_mknotpresent()
Patch series "mm/thp: Rename pmd_mknotpresent() as pmd_mknotvalid()", v2.
This series renames pmd_mknotpresent() as pmd_mknotvalid(). Before that
it drops an existing pmd_mknotpresent() definition from powerpc platform
which was never required as it defines it's pmdp_invalidate() through
subscribing __HAVE_ARCH_PMDP_INVALIDATE. This does not create any
functional change.
This rename was suggested by Catalin during a previous discussion while we
were trying to change the THP helpers on arm64 platform for migration.
https://patchwork.kernel.org/patch/11019637/
This patch (of 2):
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.
