Merge branch 'sparc32-NO_BOOTMEM'
Mike Rapoport says:
====================
sparc32: switch to NO_BOOTMEM
These patches convert sparc32 to use memblock + nobootmem.
I've made the conversion as simple as possible, just enough to allow moving
HAVE_MEMBLOCK and NO_BOOTMEM to the common SPARC configuration.
v2 changes:
* split whitespace changes to a separate patch
* address Sam's comments [1]
