  "message": "mm: fix NR_SECTION_ROOTS \u003d\u003d 0 when using using sparsemem extreme.\n\nGot this while compiling for ARM/SA1100:\n\nmm/sparse.c: In function \u0027__section_nr\u0027:\nmm/sparse.c:135: warning: \u0027root\u0027 is used uninitialized in this function\n\nThis patch follows Russell King\u0027s suggestion for a new calculation for\nNR_SECTION_ROOTS.  Thanks also to Sergei Shtylyov for pointing out the\nexistence of the macro DIV_ROUND_UP.\n\nAtsushi Nemoto observed:\n: This fix doesn\u0027t just silence the warning - it fixes a real problem.\n:\n: Without this fix, mem_section[] might have 0 size so mem_section[0]\n: will share other variable area.  For example, I got:\n:\n: c030c700 b __warned.16478\n: c030c700 B mem_section\n: c030c701 b __warned.16483\n:\n: This might cause very strange behavior.  Your patch actually fixes it.\n\nSigned-off-by: Marcelo Roberto Jimenez \u003cmroberto@cpti.cetuc.puc-rio.br\u003e\nCc: Atsushi Nemoto \u003canemo@mba.ocn.ne.jp\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Yinghai Lu \u003cyinghai@kernel.org\u003e\nCc: Sergei Shtylyov \u003csshtylyov@mvista.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
