2.6.29-rc6-git6 defconfig build failure

["Sachin P. Sant" <sachinp@in.ibm.com>]

2.6.29-rc6-git6 ppc64_defconfig build fails with

git5 did not have this problem as CONFIG_HOTPLUG was set with ppc64_defconfig.
With git6 defconfig there is no CONFIG_HOTPLUG

# grep CONFIG_HOTPLUG linux-2.6.29-rc6-git6/.config
# 

# grep CONFIG_HOTPLUG linux-2.6.29-rc6-git5/.config
CONFIG_HOTPLUG=y
CONFIG_HOTPLUG_CPU=y
CONFIG_HOTPLUG_PCI=m
# CONFIG_HOTPLUG_PCI_FAKE is not set
# CONFIG_HOTPLUG_PCI_CPCI is not set
# CONFIG_HOTPLUG_PCI_SHPC is not set
CONFIG_HOTPLUG_PCI_RPA=m
CONFIG_HOTPLUG_PCI_RPA_DLPAR=m
