[PATCH 15/35] x86/pgtable: Rename pti_set_user_pgd to pti_set_user_pgtbl

[Joerg Roedel]

From: Joerg Roedel <jroedel@xxxxxxx>

With the way page-table folding is implemented on 32 bit, we
are not only setting PGDs with this functions, but also PUDs
and even PMDs. Give the function a more generic name to
reflect that.
