  "message": "Allow nodes to exist that only contain ZONE_MOVABLE\n\nWith the introduction of kernelcore\u003d, a configurable zone is created on\nrequest.  In some cases, this value will be small enough that some nodes\ncontain only ZONE_MOVABLE.  On some NUMA configurations when this occurs,\narch-independent zone-sizing will get the size of the memory holes within\nthe node incorrect.  The value of present_pages goes negative and the boot\nfails.\n\nThis patch fixes the bug in the calculation of the size of the hole.  The\ntest case is to boot test a NUMA machine with a low value of kernelcore\u003d\nbefore and after the patch is applied.  While this bug exists in early\nkernel it cannot be triggered in practice.\n\nThis patch has been boot-tested on a variety machines with and without\nkernelcore\u003d set.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
