This patch series is a back port necessary to address the problem reported by Stefan Agner:
https://lore.kernel.org/linux-mm/bdfa44bf1c570b05d6c70898e2bbb0acf234ecdf.16...
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. Shutemov (1): mm/zsmalloc: Prepare to variable MAX_PHYSMEM_BITS
