X-Git-Tag: v2.6.14-rc1~461 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fdf26d933a8171c2a5bd35b4a5ca3b099a216a35;p=pandora-kernel.git [PATCH] x86_64: Don't do broadcast IPIs when hotplug is enabled in flat mode. The use of non-shortcut version of routines breaking CPU hotplug. The option to select this via cmdline also is deleted with the physflat patch, hence directly placing this code under CONFIG_HOTPLUG_CPU. We dont want to use broadcast mode IPI's when hotplug is enabled. This causes bad effects in send IPI to a cpu that is offline which can trip when the cpu is in the process of being kicked alive.
