2dc184c0ba [S390] hvc_iucv: Change IUCV term id and use one device as default
The patch renames the IUCV application ID from "ihvc" to "lnxhvc".
The device driver allocates one IUCV terminal device (lnxhvc0) as default.

19cdd08ba1 [S390] qdio: fix broken pointer in case of CONFIG_DEBUG_FS is disabled
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.

Also move the code out of the BUG_ON statement since it won't be

13de227bcd [S390] dasd: add device attribute to disable blocking on lost paths
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.

1301809bce [S390] dasd: send change uevents for dasd block devices
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.

237889bf0a ACPI : Use RSDT instead of XSDT by adding boot option of "acpi=rsdt"
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.

13b40a1a06 ACPI: Avoid array address overflow when _CST MWAIT hint bits are set
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

f87a1a5f6c fujitsu-laptop: Simplify SBLL/SBL2 backlight handling
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.

3a40708609 fujitsu-laptop: Add BL power, LED control and radio state information
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.

871af1210f libata: Add 32bit PIO support
This matters for some controllers and in one or two cases almost doubles
PIO performance. Add a bmdma32 operations set we can inherit and activate
it for some controllers

e427fe042c [libata] ahci: Withdraw IGN_SERR_INTERNAL for SB800 SATA
There is an issue in ATI SB600/SB700 SATA that PxSERR.E should not be
set on some conditions, which will lead to many SATA ODD error messages.
commit 55a61604cd is the workaround.
Since SB800 fixed this HW issue, IGN_SERR_INTERNAL should be withdrawn
for SB800.

4044ba58dd md: don't retry recovery of raid1 that fails due to error on source drive.
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.

efeb53c0e5 md: Allow md devices to be created by name.
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.
