Kirill A. Shutemov 215321a072 mm/zsmalloc: Prepare to variable MAX_PHYSMEM_BITS 
commit 02390b87a9459937cdb299e6b34ff33992512ec7 upstream

With boot-time switching between paging mode we will have variable
MAX_PHYSMEM_BITS.

Let's use the maximum variable possible for CONFIG_X86_5LEVEL=y
configuration to define zsmalloc data structures.

The patch introduces MAX_POSSIBLE_PHYSMEM_BITS to cover such case.
It also suits well to handle PAE special case.
