Yinghai Lu 99ab7b1944 mm: sparse: fix usemap allocation above node descriptor section ... After commit f5bf18fa22 ("bootmem/sparsemem: remove limit constraint in alloc_bootmem_section"), usemap allocations may easily be placed outside the optimal section that holds the node descriptor, even if there is space available in that section. This results in unnecessary hotplug dependencies that need to have the node unplugged before the section holding the usemap. The reason is that the bootmem allocator doesn't guarantee a linear search starting from the passed allocation goal but may start out at a much higher address absent an upper limit. Fix this by trying the allocation with the limit at the section end, then retry without if that fails. This keeps the fix from f5bf18fa22 of not panicking if the allocation does not fit in the section, but still makes sure to try to stay within the section at first.
