[PATCH -next] mm: fix build for arm64 hugetlbpage

[Sudeep Holla]

Commit ("mm: cleanup *pte_alloc* interfaces") redefined pte_alloc_map()
using pte_alloc() and fixed all the callsites. However arm64 callsite
seem to have got missed. This patch fixes the same and thereby fixing
the following build error.

arch/arm64/mm/hugetlbpage.c: In function 'huge_pte_alloc':
arch/arm64/mm/hugetlbpage.c:127:42: error: macro "pte_alloc_map" passed 4 arguments, but takes just 3
   pte = pte_alloc_map(mm, NULL, pmd, addr);
                                          ^
arch/arm64/mm/hugetlbpage.c:127:9: error: 'pte_alloc_map' undeclared (first use in this function)
   pte = pte_alloc_map(mm, NULL, pmd, addr);
         ^

Hi,

Since it's from -mm tree, I have not put the commit id causing the
breakage. Also since I don't have the original patch in my inbox, I am
posting this separately. It would be good to squash this into original
commit.

Regards,
Sudeep
