This was added part of the original commit which added MMU definitions.
commit 4f04d8f00545 ("arm64: MMU definitions").
These symbols never got used as confirmed from a git log search.
git log -p arch/arm64/ | grep PTE_TYPE_FAULT git log -p arch/arm64/ | grep PMD_TYPE_FAULT
These probably meant to identify non present entries which can now be achieved with PMD_SECT_VALID or PTE_VALID bits. Hence just drop these unused symbols which are not required anymore.
