Alison Schofield 9b99c17f75 x86/numa: Fix the address overlap check in numa_fill_memblks() ... numa_fill_memblks() fills in the gaps in numa_meminfo memblks over a physical address range. To do so, it first creates a list of existing memblks that overlap that address range. The issue is that it is off by one when comparing to the end of the address range, so memblks that do not overlap are selected. The impact of selecting a memblk that does not actually overlap is that an existing memblk may be filled when the expected action is to do nothing and return NUMA_NO_MEMBLK to the caller. The caller can then add a new NUMA node and memblk. Replace the broken open-coded search for address overlap with the memblock helper memblock_addrs_overlap(). Update the kernel doc and in code comments.
