arm64/mm: add addr parameter to __set_ptes_anysz()

arm64/mm: add addr parameter to __set_ptes_anysz()

Patch series "Support page table check on PowerPC", v18.

Support page table check on PowerPC.  Page table check tracks the usage of
of page table entries at each level to ensure that anonymous mappings have
at most one writable consumer, and likewise that file-backed mappings are
not simultaneously also anonymous mappings.

In order to support this infrastructure, a number of helpers or stubs must
be defined or updated for all powerpc platforms.  Additionally, we
separate set_pte_at() and set_pte_at_unchecked(), to allow for internal,
uninstrumented mappings.

On some PowerPC platforms, implementing
{pte,pmd,pud}_user_accessible_page() requires the address.  We revert
previous changes that removed the address parameter from various
interfaces, and add it to some other interfaces, in order to allow this.

For now, we don't allow page table check alongside HUGETLB_PAGE, due to
the arch-specific complexity of set_huge_page_at().  (I'm sure I could
figure this out, but I have to get this version on this list before I
leave my job.)

This series was initially written by Rohan McLure, who has left IBM and is
no longer working on powerpc.

This patch (of 18):

To provide support for page table check on powerpc, we need to reinstate
the address parameter in several functions, including
page_table_check_{ptes,pmds,puds}_set().

In preparation for this, add the addr parameter to arm64's
__set_ptes_anysz() and change its callsites accordingly.
