Add ide_check_ireason() function that handles all ATAPI devices.
Reorganize all unlikely cases in ireason checking further down in the
code path.
In addition, add PFX for printks originating from ide-atapi. Finally,
remove ide_cd_check_ireason.

Now that we use a static request_sense buffer, use it instead of the
first 18 bytes only. Also, remove sense-arg to cdrom_analyze_sense_data
and cdrom_log_sense since we can access it through drive->sense_data
now.

ide-tape used to issue READ POSITION in several places and the
evaluation of the returned READ POSITION data was done in the
->pc_callback. Convert it to use local buffer and move that
evaluation chunk in the idetape_read_position(). Additionally, fold
idetape_create_read_position_cmd() into it, too, thus concentrating READ
POSITION handling in one method only and making all places call that.
Finally, mv {idetape,ide_tape}_read_position.

This is in preparation of removing ide_atapi_pc. Expose the buffer as an
argument to ide_queue_pc_tail with later replacing it with local buffer
or even kmalloc'ed one if needed due to stack usage constraints.
Also, add the possibility of passing a NULL-ptr buffer for cmds which
don't transfer data besides the cdb. While at it, switch to local buffer
in idetape_get_mode_sense_results().
There should be no functional change resulting from this patch.

After the recent struct request cleanups, blk_rq_bytes() is guaranteed
to be valid and is the current total length of the rq's bio. Use that
instead of pc->req_xfer in the do_request() path after the command has
been queued
The remaining usage of pc->req_xfer now is only until we map the rq to a
bio.
While at it:
- remove local caching of rq completion length in ide_tape_issue_pc()

ide-tape had a potential bug for fs requests when preparing the command
packet: it was writing the transfer length as a number of fixed blocks.
However, the block layer implies 512 byte blocks and ide-tape can have
other block sizes so account for that too.
ide-floppy does this calculation properly with the block size factor
(floppy->bs_factor).

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.
In cases of hardware errors it can inspect the sense data in the irb,
but when the reason is internal (e.g. start_IO failed) then it needs
a meaningfull return code.

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.
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()

Now all the DRM debug info will be reported if the boot option of
"drm.debug=1" is added. Sometimes it is inconvenient to get the debug
info in KMS mode. We will get too much unrelated info.
This will separate several DRM debug levels and the debug level can be used
to print the different debug info. And the debug level is controlled by the
module parameter of drm.debug
In this patch it is divided into four debug levels;
drm_core, drm_driver, drm_kms, drm_mode.
At the same time we can get the different debug info by changing the debug
level. This can be done by adding the module parameter. Of course it can
be changed through the /sys/module/drm/parameters/debug after the system is
booted.
Four debug macro definitions are provided.
DRM_DEBUG(fmt, args...)
DRM_DEBUG_DRIVER(prefix, fmt, args...)
DRM_DEBUG_KMS(prefix, fmt, args...)
DRM_DEBUG_MODE(prefix, fmt, args...)
When the boot option of "drm.debug=4" is added, it will print the debug info
using DRM_DEBUG_KMS macro definition.
When the boot option of "drm.debug=6" is added, it will print the debug info
using DRM_DEBUG_KMS/DRM_DEBUG_DRIVER.
Sometimes we expect to print the value of an array.
For example: SDVO command,
In such case the following four DRM debug macro definitions are added:
DRM_LOG(fmt, args...)
DRM_LOG_DRIVER(fmt, args...)
DRM_LOG_KMS(fmt, args...)
DRM_LOG_MODE(fmt, args...)
