Subject: selftests/mm: move psize(), pshift() into vm_utils.c
Date: Thu, 1 Jun 2023 18:33:55 -0700

This is in preparation for linking test programs with both vm_utils.c and
uffd-common.c.  The static inline routines would prevent that, and there
is no particular need for inlining here, so turn these into normal
functions that are more flexible to build and link.
