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: NMartin Schwidefsky <schwidefsky@de.ibm.com>

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.

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.

If a DASD requests is started with dasd_sleep_on and fails, then the calling function may need to know the reason for the failure.

Some functions called as a late_initcall depend on completely initialized devices. Since commit f3445a1a 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. Fix this by calling async_synchronize_full at the end of the related init functions.

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.

The tty3270_notifier that calls tty_register_device / tty_unregister_device is harmful in two ways: 1) the device node that is create is wrong because the minor numbers for 3270 tty start with 1 and tty_notifier passes the minor as index. 2) If 1) is corrected you'll get a warning: WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x4c/0x60() sysfs: duplicate filename '227:1' can not be created The 227:1 link is already created by raw3270_create_attributes to refer to ../../class/tty/tty<devno>.

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.

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.
