Tejun Heo 847854f598 memblock: Fix size aligning of memblock_alloc_base_nid() ... memblock allocator aligns @size to @align to reduce the amount of fragmentation. Commit: 7bd0b0f0da ("memblock: Reimplement memblock allocation using reverse free area iterator") Broke it by incorrectly relocating @size aligning to memblock_find_in_range_node(). As the aligned size is not propagated back to memblock_alloc_base_nid(), the actually reserved size isn't aligned. While this increases memory use for memblock reserved array, this shouldn't cause any critical failure; however, it seems that the size aligning was hiding a use-beyond-allocation bug in sparc64 and losing the aligning causes boot failure. The underlying problem is currently being debugged but this is a proper fix in itself, it's already pretty late in -rc cycle for boot failures and reverting the change for debugging isn't difficult. Restore the size aligning moving it to memblock_alloc_base_nid(). Reported-by: Meelis Roos <mroos@linux.ee> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: David S.
