48fb2688aa ide: remove drive->driveid
* Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling
  to ide_get_identity_ioctl().

* Use temporary buffer in ide_get_identity_ioctl() instead
  of accessing drive->id directly.

* Add ide_id_to_hd_driveid() inline to convert raw id into
  struct hd_driveid format (needed on big-endian).

* Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(),
  cleanup ide_fix_driveid() and switch ide to use use raw id.

* Remove no longer needed drive->driveid.

  This leaves us with 3 users of struct hd_driveid in tree:
  - arch/um/drivers/ubd_kern.c
  - drivers/block/xsysace.c
  - drivers/usb/storage/isd200.c

While at it:

* Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.

4dde4492d8 ide: make drive->id an union (take 2)
Make drive->id an unnamed union so id can be accessed either by using
'u16 *id' or 'struct hd_driveid *driveid'.  Then convert all existing
drive->id users accordingly (using 'u16 *id' when possible).

This is an intermediate step to make ide 'struct hd_driveid'-free.

While at it:

- Add missing KERN_CONTs in it821x.c.

- Use ATA_ID_WORDS and ATA_ID_*_LEN defines.

- Remove unnecessary checks for drive->id.

- s/drive_table/table/ in ide_in_drive_list().

408aec3c6c [S390] 3215: Remove tasklet.
The 3215 console irq handler used to schedule a tasklet. However the
console irq handler also gets called from the infamous cio_tpi()
function. Which in turn does something like

local_bh_disable()
[call console irq handler]
_local_bh_enable()

_local_bh_enable() prevents execution of softirqs, which is intended
within cio_tpi(). However there might be a new softirq pending because
irq handler scheduled a tasklet.
In order to prevent this behaviour we just get rid of the tasklet.
It's not doing much anyway.

2332ce1a97 [S390] console flush on panic / reboot
The s390 console drivers use the unblank callback of the console
structure to flush the console buffer. In case of a panic or a
reboot the CPU doing the callback can block on the console i/o.
The other CPUs in the system continue to work. For panic this is
not a good idea.

Replace the unblank callback with proper panic/reboot notifier.
These get called after all but one CPU have been stopped.

15e86b0c75 [S390] introduce dirty bit for kvm live migration
This patch defines a dirty bit in the PGSTE that can be used to implement
dirty pages logging for KVM's live migration. The bit is set in the
ptep_rcp_copy function, which is called to save dirty and referenced information
from the storage key in the PGSTE. The bit can be tested and reset by KVM using
the kvm_s390_test_and_clear_page_dirty function that is introduced by this patch.

3ce66093f5 [S390] xpram: per device block request queues.
The xpram driver uses a single block device queue for all of its

clean up all sysfs files. The next time the xpram module is loaded
you'll get warnings:

  WARNING: at fs/sysfs/dir.c:463 sysfs_add_one+0x5e/0x64()
  sysfs: duplicate filename '35:0' can not be created
  Modules linked in: xpram(+) [last unloaded: xpram]

Followed by the usual WARN_ON output, followed by an error message
from kobject_add_internal, followed by a badness in genhd. Allocating
a block queue per device fixes this.

b2bbb642ac [S390] cio: Correct use of ! and &
In commit e6bafba5b4, a bug was fixed that
involved converting !x & y to !(x & y).  The code below shows the same
pattern, and thus should perhaps be fixed in the same way.  In particular,
the result of !scsw_stctl(&request->irb.scsw) & SCSW_STCTL_STATUS_PEND is
always just !scsw_stctl(&request->irb.scsw).

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@ expression E; constant C; @@
(
  !E & !C
|
- !E & C
+ !(E & C)
)

4bcb3a3718 [S390] qdio: speed up multicast traffic on full HiperSocket queue
If an asynchronous HiperSockets queue runs full, no further packet
can be sent. In this case the next initiative to give transmitted
skbs back to the stack is triggered only by a 10-seconds qdio timer.
This timer has been introduced for low multicast traffic scenarios
to guarantee freeing of skbs in a limited amount of time. For high
HiperSocket multicast traffic scenarios progress checking on the
outbound queue should be enforced by tasklet rescheduling.
