The patch renames the IUCV application ID from "ihvc" to "lnxhvc".
The device driver allocates one IUCV terminal device (lnxhvc0) as default.

If CONFIG_DEBUG_FS is disabled debugfs_create_file returns -ENODEV instead
of zero. Since the return value is stored and used at shutdown to remove
existing entries an OOPS may be triggered.
Add a check of the debugfs_create_file return value and in case of an error
set the entry to NULL so it will be ignored at shutdown.

When the connection between host and storage server is lost, the
dasd device driver usually blocks all I/O on affected devices and
waits for them to reappear. In some setups however it would be
better if the I/O is returned as error so that device can be
recovered by some other means, eg. in a raid or multipath setup.

When a DASD device enters or leaves the 'online' state we need to
trigger change events for the respective disk and partitions.
These extra events are needed because when disk and partitions are
first added, udev rules that try to read disk labels or other data
may fail as the disk may not yet be ready.

On some boxes there exist both RSDT and XSDT table. But unfortunately
sometimes there exists the following error when XSDT table is used:
a. 32/64X address mismatch
b. The 32/64X FACS address mismatch
In such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.

The Cx Register address obtained from the _CST object is used as the MWAIT
hints if the register type is FFixedHW. And it is used to check whether
the Cx type is supported or not.
On some boxes the following Cx state package is obtained from _CST object:
>{
ResourceTemplate ()
{
Register (FFixedHW,
0x01, // Bit Width
0x02, // Bit Offset
0x0000000000889759, // Address
0x03, // Access Size
)
},
0x03,
0xF5,
0x015E }
In such case we should use the bit[7:4] of Cx address to check whether
the Cx type is supported or not.
mask the MWAIT hint to avoid array address overflow

GBLS and GBLL only differ in the clearing of the GHKS flag, so there is no need
to have two backlight level readouts. Also, per Peter Gruber, the need for the
BLNF check has disappeared.
As a result, cleanups can be made in the code. This has been tested on the both
the S6410 and the S6420 platforms and causes no functionality regressions, on
the console without X or within X. One module parameter to disable the hotkeys
is dropped, as we only ever took one codepath anyway.

The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes
state information that is now reported in additional platform files (whether the
radios are killed by the hardware switch or operational, whether the machine is
docked and whether the lid is open).
Support for the backlight class is now extended with the ability to power the
backlight on & off. Optional support for the LED class allows the keyboard
headlamps found on the U810 netbook and the Fujitsu logo illumination on the
P8010 notebook to be turned on & off.
This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.

If a raid1 has only one working drive and it has a sector which
gives an error on read, then an attempt to recover onto a spare will
fail, but as the single remaining drive is not removed from the
array, the recovery will be immediately re-attempted, resulting
in an infinite recovery loop.
So detect this situation and don't retry recovery once an error
on the lone remaining drive is detected.
Allow recovery to be retried once every time a spare is added
in case the problem wasn't actually a media error.

Using sequential numbers to identify md devices is somewhat artificial.
Using names can be a lot more user-friendly.
Also, creating md devices by opening the device special file is a bit
awkward.
So this patch provides a new option for creating and naming devices.
Writing a name such as "md_home" to
/sys/modules/md_mod/parameters/new_array
will cause an array with that name to be created. It will appear in
/sys/block/ /proc/partitions and /proc/mdstat as 'md_home'.
It will have an arbitrary minor number allocated.
md devices that a created by an open are destroyed on the last
close when the device is inactive.
For named md devices, they will not be destroyed until the array
is explicitly stopped, either with the STOP_ARRAY ioctl or by
writing 'clear' to /sys/block/md_XXXX/md/array_state.
The name of the array must start 'md_' to avoid conflict with
other devices.
