2009-06-16[S390] pm: vmwatchdog power management callbacks.Christian Borntraeger
This patch implements suspend/hibernation for the vmwatchdog driver. The pm_notifier_callchain is used to get control on PM events. Since watchdog operation and suspend cannot work together in a reliable fashion, the open flag is also used to prevent suspend and open from happening at the same time. The watchdog can also be active with no open file descriptor. This patch adds another flag which is only changed in vmwdt_keep_alive and vmwdt_disable.

2009-06-16[S390] pm: con3215 power management callbacksMartin Schwidefsky
Introduce the power management callbacks to the 3215 console. On suspend the console buffer is flushed to the 3215 device to have an empty console buffer. Printks done while the 3215 device is suspended are buffered in the 64K buffer of the 3215 device. If the buffer is full new messages will push out the oldest messages to make room for the most recent message. On resume the buffered messages are printed. If the system panics before the 3215 device is resumed ccw_device_force_console is used to get the console working again. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-16[S390] cio: force console functionMartin Schwidefsky
If something goes wrong in a suspend / resume cycle a ccw based console if very likely in the suspended state and cannot print anything. Introduce ccw_device_force_console to force the wake up of the console device to be able to print the oops message. The console device drivers should use this function only if the system paniced.

2009-06-16[S390] pm: dasd power management callbacks.Stefan Haberland
Introduce the power management callbacks to the dasd driver. On suspend the dasd devices are stopped and removed from the focus of alias management. On resume they are reinitialized by rereading the device characteristics and adding the device to the alias management. In case the device has gone away during suspend it will caught in the suspend state with stopped flag set to UNRESUMED. After it appears again the restore function is called again.

2009-06-15s390: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions. Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few typos in my original version of this patch.

2009-06-12[S390] dasd: sync after async probeSebastian Ott
Some functions called as a late_initcall depend on completely initialized devices. Since commit f3445a1a656bc26b07946cc6d20de1ef07c8d116 the dasd driver uses the new async framework and relies on the fact that synchronization is done in prepare_namespace which is called after the late_initcalls.

2009-06-12[S390] 3270: lock dependency fixesMartin Schwidefsky
Lockdep found a problem with the lock order of the view lock and the ccw device lock. raw3270_activate_view/raw3270_deactivate_view first take the ccw device lock then call the activate/deactivate functions of the view which take view lock. The update functions of the con3270/tty3270 view will first take the view lock, then take the ccw device lock. To fix this the activate/deactivate functions are changed to avoid taking the view lock by moving the functions calls that modify the 3270 output buffer to the update function which is called by a timer.

2009-05-29net: convert unicast addr listJiri Pirko
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.
