#     powerpc/mm: Define MAX_PHYSMEM_BITS for all 64-bit configs
#     
#     The recent commit 8bc086899816 ("powerpc/mm: Only define
#     MAX_PHYSMEM_BITS in SPARSEMEM configurations") removed our definition
#     of MAX_PHYSMEM_BITS when SPARSEMEM is disabled.
#     
#     This inadvertently broke some 64-bit FLATMEM using configs with eg:
#     
#       arch/powerpc/include/asm/book3s/64/mmu-hash.h:584:6: error: "MAX_PHYSMEM_BITS" is not defined, evaluates to 0
#        #if (MAX_PHYSMEM_BITS > MAX_EA_BITS_PER_CONTEXT)
#             ^~~~~~~~~~~~~~~~
#     
#     Fix it by making sure we define MAX_PHYSMEM_BITS for all 64-bit
#     configs regardless of SPARSEMEM.
#     
#     Fixes: 8bc086899816 ("powerpc/mm: Only define MAX_PHYSMEM_BITS in SPARSEMEM configurations")
