#     powerpc/mm/book3s/radix: Add mapping statistics
#     
#     Add statistics that show how memory is mapped within the kernel linear mapping.
#     This is similar to commit 37cd944c8d8f ("s390/pgtable: add mapping statistics")
#     
#     We don't do this with Hash translation mode. Hash uses one size (mmu_linear_psize)
#     to map the kernel linear mapping and we print the linear psize during boot as
#     below.
#     
#     "Page orders: linear mapping = 24, virtual = 16, io = 16, vmemmap = 24"
#     
#     A sample output looks like:
#     
#     DirectMap4k:           0 kB
#     DirectMap64k:       18432 kB
#     DirectMap2M:     1030144 kB
#     DirectMap1G:    11534336 kB
