2012-11-06s390/sclp: fix addressing mode clobberHeiko Carstens
The early mini sclp driver may be called in zArch mode either in 31 or 64 bit addressing mode. If called in 31 bit addressing mode the new external interrupt psw however would switch to 64 bit addressing mode. This would cause an addressing exception within the interrupt handler, since the code didn't expect the zArch/31 bit addressing mode combination. Fix this by setting the new psw addressing mode bits so they fit the current addressing mode.

2012-11-06device_cgroup: fix RCU usageTejun Heo
dev_cgroup->exceptions is protected with devcgroup_mutex for writes and RCU for reads; however, RCU usage isn't correct. * dev_exception_clean() doesn't use RCU variant of list_del() and kfree(). The function can race with may_access() and may_access() may end up dereferencing already freed memory. Use list_del_rcu() and kfree_rcu() instead. * may_access() may be called only with RCU read locked but doesn't use RCU safe traversal over ->exceptions. Use list_for_each_entry_rcu().

2012-11-05PCI/PM: Fix proc config reg access for D3cold and bridge suspendingHuang Ying
In https://bugzilla.kernel.org/show_bug.cgi?id=48981 Peter reported that /proc/bus/pci/??/??.? does not work for 3.6. This is because the device configuration space registers are not accessible if the corresponding parent bridge is suspended or the device is put into D3cold state. This is the same as /sys/bus/pci/devices/0000:??:??.?/config access issue. So the function used to solve sysfs issue is used to solve this issue. This patch moves pci_config_pm_runtime_get()/_put() from pci/pci-sysfs.c to pci/pci.c and makes them extern so they can be used by both the sysfs and proc paths.
