  "message": "memory hotplug: fix early allocation handling\n\nTrying to add memory via add_memory() from within an initcall function\nresults in\n\nbootmem alloc of 163840 bytes failed!\nKernel panic - not syncing: Out of memory\n\nThis is caused by zone_wait_table_init() which uses system_state to decide\nif it should use the bootmem allocator or not.\n\nWhen initcalls are handled the system_state is still SYSTEM_BOOTING but\nthe bootmem allocator doesn\u0027t work anymore.  So the allocation will fail.\n\nTo fix this use slab_is_available() instead as indicator like we do it\neverywhere else.\n\n[akpm@linux-foundation.org: coding-style fix]\nReviewed-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
