  "message": "drivers/base/memory.c: prohibit offlining of memory blocks with missing sections\n\nCommit bdee237c0343 (\"x86: mm: Use 2GB memory block size on large-memory\nx86-64 systems\") and 982792c782ef (\"x86, mm: probe memory block size for\ngeneric x86 64bit\") introduced large block sizes for x86.  This made it\npossible to have multiple sections per memory block where previously,\nthere was a only every one section per block.\n\nSince blocks consist of contiguous ranges of section, there can be holes\nin the blocks where sections are not present.  If one attempts to\noffline such a block, a crash occurs since the code is not designed to\ndeal with this.\n\nThis patch is a quick fix to gaurd against the crash by not allowing\nblocks with non-present sections to be offlined.\n\nAddresses https://bugzilla.kernel.org/show_bug.cgi?id\u003d107781\n\nSigned-off-by: Seth Jennings \u003csjennings@variantweb.net\u003e\nReported-by: Andrew Banman \u003cabanman@sgi.com\u003e\nCc: Daniel J Blueman \u003cdaniel@numascale.com\u003e\nCc: Yinghai Lu \u003cyinghai@kernel.org\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Russ Anderson \u003crja@sgi.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
