Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

Radix boot looks like this:

 -----------------------------------------------------
 phys_mem_size     = 0x200000000
 dcache_bsize      = 0x80
 icache_bsize      = 0x80
 cpu_features      = 0x0000c06f8f5fb1a7
   possible        = 0x0000fbffcf5fb1a7
   always          = 0x00000003800081a1
 cpu_user_features = 0xdc0065c2 0xaee00000
 mmu_features      = 0xbc006041
 firmware_features = 0x0000000010000000
 hash-mmu: ppc64_pft_size    = 0x0
 hash-mmu: kernel vmalloc start   = 0xc008000000000000
 hash-mmu: kernel IO start        = 0xc00a000000000000
 hash-mmu: kernel vmemmap start   = 0xc00c000000000000
 -----------------------------------------------------

It's misleading to see hash-mmu there. After fix:

 -----------------------------------------------------
 phys_mem_size     = 0x200000000
 dcache_bsize      = 0x80
 icache_bsize      = 0x80
 cpu_features      = 0x0000c06f8f5fb1a7
   possible        = 0x0000fbffcf5fb1a7
   always          = 0x00000003800081a1
 cpu_user_features = 0xdc0065c2 0xaee00000
 mmu_features      = 0xbc006041
 firmware_features = 0x0000000010000000
 vmalloc start     = 0xc008000000000000
 IO start          = 0xc00a000000000000
 vmemmap start     = 0xc00c000000000000
 -----------------------------------------------------

Hash has the same text misalignment problem which is also corrected.

v2: avoid adding an ifdef to generic code.
