[PATCH] arm64/mm: Drop pte_huge()

[PATCH] arm64/mm: Drop pte_huge()

[Anshuman Khandual]

This helper is required from generic huge_pte_alloc() which is available
when arch subscribes ARCH_WANT_GENERAL_HUGETLB. arm64 implements it's own
huge_pte_alloc() and does not depend on the generic definition. Drop this
helper which is redundant on arm64.

I had this on my list for 5.3 but the arm64 for-next/core was already
frozen. Will can queue this whenever he sees fit.
