Define a version of memory_block_size_bytes() for powerpc/pseries such that a memory block spans an entire lmb.I hope I am not missing anything obvious, but why not just call it lmb_size, why do we need memblock_size? Is lmb_size == memblock_size after your changes true for all platforms?What is an lmb? I don't recall anything like lmb being referred to in the rest of the kernel.Heh. It's the OpenFirmware name for a Logical Memory Block. Basically what we use to determine the SECTION_SIZE on powerpc. Probably not the best terminology to use elsewhere in the kernel.
Agreed for the kernel, this patch was for powerpc/pseries, hence was checking in this context. -- Three Cheers, Balbir
