Harvey Harrison ddc81ed2c5 remove sparse warning for mmzone.h 
include/linux/mmzone.h:640:22: warning: potentially expensive pointer subtraction

Calculate the offset into the node_zones array rather than the index
using casts to (char *) and comparing against the index * sizeof(struct zone).

On X86_32 this saves a sar, but code size increases by one byte per
is_highmem() use due to 32-bit cmps rather than 16 bit cmps.

Before:
 207:   2b 80 8c 07 00 00       sub    0x78c(%eax),%eax
 20d:   c1 f8 0b                sar    $0xb,%eax
 210:   83 f8 02                cmp    $0x2,%eax
 213:   74 16                   je     22b <kmap_atomic_prot+0x144>
 215:   83 f8 03                cmp    $0x3,%eax
 218:   0f 85 8f 00 00 00       jne    2ad <kmap_atomic_prot+0x1c6>
 21e:   83 3d 00 00 00 00 02    cmpl   $0x2,0x0
 225:   0f 85 82 00 00 00       jne    2ad <kmap_atomic_prot+0x1c6>
 22b:   64 a1 00 00 00 00       mov    %fs:0x0,%eax

After:
 207:   2b 80 8c 07 00 00       sub    0x78c(%eax),%eax
 20d:   3d 00 10 00 00          cmp    $0x1000,%eax
 212:   74 18                   je     22c <kmap_atomic_prot+0x145>
 214:   3d 00 18 00 00          cmp    $0x1800,%eax
 219:   0f 85 8f 00 00 00       jne    2ae <kmap_atomic_prot+0x1c7>
 21f:   83 3d 00 00 00 00 02    cmpl   $0x2,0x0
 226:   0f 85 82 00 00 00       jne    2ae <kmap_atomic_prot+0x1c7>
 22c:   64 a1 00 00 00 00       mov    %fs:0x0,%eax
