From: James Bottomley Date: Fri, 24 Feb 2006 21:04:11 +0000 (-0800) Subject: [PATCH] voyager: fix the cpu_possible_map to make voyager boot again X-Git-Tag: v2.6.16-rc5~38 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f68a106f224c21148c5264a429fac149dc7ad0ac;p=linux-2.6 [PATCH] voyager: fix the cpu_possible_map to make voyager boot again Right at the moment (thanks to a patch from Andrew), cpu_possible_map on voyager is CPU_MASK_NONE, which means the machine always thinks it has no CPUs. Fix that by doing an early initialisation of the cpu_possible_map from the cpu_phys_present_map.
