+
+g_malloc0(is getting a -ve value) and then fails with a trap.

+The above I am referring from hw/ppc/spapr.c

+
+Please don't add patches to the bug tracker, post them to the qemu-devel (and qemu-ppc in this case) mailing list instead. You even don't have to join the mailing lists if you don't like to, posting to them is allowed for everybody. See https://www.qemu.org/contribute/report-a-bug/ and http://wiki.qemu.org/Contribute/SubmitAPatch for details. Thanks!
+
+Looking at your patch, I think you should also check for "<= 0" instead of just "< 0" ... since maxcpus = 0 also does not make much sense.
+
+Sure will do the changes and update. Seems one of my colleague did it already (sent patch to devel list)
+https://lists.nongnu.org/archive/html/qemu-devel/2017-08/msg05345.html
+I will pass your review comments to her for modification.
+
+Thanks for your review.
+
+Fixed in master, commit c0dd109919, which will be in the upcoming 2.11 release.
