Subject: xen: initialize platform-pci even if xen_emul_unplug=never
X-Git-Tag: v3.4-rc1~94^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9136d207f0c05c96c6b9c980fa7f7fd541a65a8;p=pandora-kernel.git

xen: initialize platform-pci even if xen_emul_unplug=never

When xen_emul_unplug=never is specified on kernel command line
reading files from /sys/hypervisor is broken (returns -EBUSY).
It is caused by xen_bus dependency on platform-pci and
platform-pci isn't initialized when xen_emul_unplug=never is
specified.

Fix it by allowing platform-pci to ignore xen_emul_unplug=never,
and do not intialize xen_[blk|net]front instead.
