Subject: [PATCH 1/2] powerpc/mm: remove pmd_huge/pud_huge stubs and include hugetlb.h
Date: Tue, 12 Nov 2019 11:45:57 -0800	[thread overview]
Message-ID: <20191112194558.139389-2-mike.kravetz@oracle.com> (raw)
In-Reply-To: <20191112194558.139389-1-mike.kravetz@oracle.com>

This removes the power specific stubs created by commit aad71e3928be
("powerpc/mm: Fix build break with RADIX=y & HUGETLBFS=n") used when
!CONFIG_HUGETLB_PAGE.  Instead, it addresses the build break by
getting the definitions from <linux/hugetlb.h>.  This allows the
macros in <linux/hugetlb.h> to be replaced with static inlines.
