powerpc/mm/hash: Remove the superfluous bitwise operation when find hpte group When computing the starting slot number for a hash page table group we used to do this hpte_group = ((hash & htab_hash_mask) * HPTES_PER_GROUP) & ~0x7UL; Multiplying with 8 (HPTES_PER_GROUP) imply the last three bits are 0. Hence we really don't need to clear then separately. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
