Revision 8bc086899816214fbc6047c9c7e15fcab49552bf authored by Ben Hutchings on 17 March 2019, 01:17:56 UTC, committed by Michael Ellerman on 20 March 2019, 13:16:45 UTC
MAX_PHYSMEM_BITS only needs to be defined if CONFIG_SPARSEMEM is enabled, and that was the case before commit 4ffe713b7587 ("powerpc/mm: Increase the max addressable memory to 2PB"). On 32-bit systems, where CONFIG_SPARSEMEM is not enabled, we now define it as 46. That is larger than the real number of physical address bits, and breaks calculations in zsmalloc: mm/zsmalloc.c:130:49: warning: right shift count is negative MAX(32, (ZS_MAX_PAGES_PER_ZSPAGE << PAGE_SHIFT >> OBJ_INDEX_BITS)) ^~ ... mm/zsmalloc.c:253:21: error: variably modified 'size_class' at file scope struct size_class *size_class[ZS_SIZE_CLASSES]; ^~~~~~~~~~ Fixes: 4ffe713b7587 ("powerpc/mm: Increase the max addressable memory to 2PB") Cc: stable@vger.kernel.org # v4.20+ Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
