  "message": "powerpc: Fix memory hotplug with sparse vmemmap\n\nPrevious commit 46723bfa540... introduced a new config option\nHAVE_BOOTMEM_INFO_NODE that ended up breaking memory hot-remove for ppc\nwhen sparse vmemmap is not defined.\n\nThis patch defines HAVE_BOOTMEM_INFO_NODE for ppc and adds the call to\nregister_page_bootmem_info_node. Without this we get a BUG_ON for memory\nhot remove in put_page_bootmem().\n\nThis also adds a stub for register_page_bootmem_memmap to allow ppc to build\nwith sparse vmemmap defined. Leaving this as a stub is fine since the same\nvmemmap addresses are also handled in vmemmap_populate and as such are\nproperly mapped.\n\nSigned-off-by: Nathan Fontenot \u003cnfont@linux.vnet.ibm.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCC: \u003cstable@vger.kernel.org\u003e [v3.9+]\n",
