I assume you already know... sparc64 uses memblock, but sparc32 does not. I looked at using memblock for sparc32 some time ago but got distracted by other stuff. I recall from back then that these ackward named variables confused me, and some of my confusion was likely rooted in sparc32 using max_low_pfn for something elase than others do. I have no plans to look into adding memblock support for sparc32 right now. But may eventually do so when I get some spare time.
