This patch series is a back port necessary to address the problem reported by Stefan Agner: https://lore.kernel.org/linux-mm/bdfa44bf1c570b05d6c70898e2bbb0acf234ecdf.1604762181.git.stefan@xxxxxxxx/ but which ended up being addressed by Arnd in a slightly different way from Stefan's submission. The first patch from Kirill is back ported in order to have MAX_POSSIBLE_PHYSMEM_BITS be acted on my the zsmalloc.c code. Arnd Bergmann (1): arch: pgtable: define MAX_POSSIBLE_PHYSMEM_BITS where needed Kirill A.
