[PATCH 6.6.y 5/6] mm: provide mm_struct and address to huge_ptep_get()

[Sasha Levin <sashal@kernel.org>]

From: Christophe Leroy <christophe.leroy@csgroup.eu>

[ Upstream commit e6c0c03245b14d6c205814aee67128257d0bea84 ]

On powerpc 8xx huge_ptep_get() will need to know whether the given ptep is
a PTE entry or a PMD entry.  This cannot be known with the PMD entry
itself because there is no easy way to know it from the content of the
entry.

So huge_ptep_get() will need to know either the size of the page or get
the pmd.

In order to be consistent with huge_ptep_get_and_clear(), give mm and
address to huge_ptep_get().
