Can this be inlined? instead of defining the define...

The latest patch from Ilya makes it:

Can SZ_* defines from arch/arm/include/asm/sizes.h be used here?

These can be removed, as already done in a recent patch from Thomas:

This is also, removed by a patch from Thomas:

Can this be aligned with all the others?

Can this have a spaces around the '*' operator?

Here (and in some more places) you have spaces for alignment.
