Subject: [PATCH v2 17/23] sh/hugetlb: pte_alloc_huge() pte_offset_huge()
In-Reply-To: <a4963be9-7aa6-350-66d0-2ba843e1af44@google.com>

Precedence: bulk

pte_alloc_map() expects to be followed by pte_unmap(), but hugetlb omits
that: to keep balance in future, use the recently added pte_alloc_huge()
instead; with pte_offset_huge() a better name for pte_offset_kernel().
