Christophe Leroy 03bb2d6590 powerpc: get hugetlbpage handling more generic ... Today there are two implementations of hugetlbpages which are managed by exclusive #ifdefs: * FSL_BOOKE: several directory entries points to the same single hugepage * BOOK3S: one upper level directory entry points to a table of hugepages In preparation of implementation of hugepage support on the 8xx, we need a mix of the two above solutions, because the 8xx needs both cases depending on the size of pages: * In 4k page size mode, each PGD entry covers a 4M bytes area. It means that 2 PGD entries will be necessary to cover an 8M hugepage while a single PGD entry will cover 8x 512k hugepages. * In 16 page size mode, each PGD entry covers a 64M bytes area. It means that 8x 8M hugepages will be covered by one PGD entry and 64x 512k hugepages will be covers by one PGD entry. This patch: * removes #ifdefs in favor of if/else based on the range sizes * merges the two huge_pte_alloc() functions as they are pretty similar * merges the two hugetlbpage_init() functions as they are pretty similar Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> (v3) Signed-off-by: Scott Wood <oss@buserror.net>		2016-12-09 22:48:09 -06:00
