Subject: [PATCH V2 0/2] mm/thp: Rename pmd_mknotpresent() as pmd_mkinvalid()

This series renames pmd_mknotpresent() as pmd_mkinvalid(). 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 series is based on v5.7-rc2.

Boot tested on arm64 and x86 platforms.
Built tested on many other platforms including the ones changed here.

Changes in V2:

- Changed pmd_mknotvalid() as pmd_mkinvalid() per Will

Changes in V1: (https://patchwork.kernel.org/project/linux-mm/list/?series=259139)
