The function shouldn't have existed in the first place (not MSS-aware).
Introduce a new function ccw_device_get_id() that extracts the
ccw_dev_id structure of a ccw device and convert all users of
_ccw_device_get_device_number to ccw_device_get_id.Signed-off-by: Cornelia Huck

The current ccw_device_set_options() sets a specified mask of options
and clears those not specified, but there is no way to find out which
options have already been set.In order to fix this up, introduce the following interface changes:
ccw_device_set_options() now only sets the specified bits, but does
not clear those that are not specified.ccw_device_clear_options() clears the specified bits.
ccw_device_set_options_mask() provides the old semantics (setting only
the specified bits and clearing the others).Device drivers now work as expected. qdio has been adapted.

The grace period handling introduced needless complexity. It didn't
help the dasd driver (which can handle terminated I/O just well),
and it doesn't help for long running channel programs (which won't
complete during the grace period anyway). Terminating I/O using a
path that just disappeared immediately is much more consistent with
what the user expects.Signed-off-by: Cornelia Huck

Reappearing channel paths are sometimes not utilized by CCW devices
because path verification incorrectly relies on path-operational-mask
information which is not updated until a channel path has been used
again.
Modify path verification procedure to always query all available paths
to a device.Signed-off-by: Peter Oberparleiter

CHPIDs that are logically varied off will not be removed from
a CCW device's path group because resign-from-pathgroup command is
issued with invalid path mask of 0 because internal CCW operations
are masked by the logical path mask after the relevant bits are
cleared by the vary operation.
Do not apply logical path mask to internal operations.Signed-off-by: Peter Oberparleiter

After setting a path to a dasd offline at the SE, I/O hangs on that
dasd for 5 minutes, then continues.
I/O for which an interrupt will not be reported after the channel
path has been disabled was not terminated by the common I/O layer,
causing the dasd MIH to hit after 5 minutes.Be more aggressive in terminating I/O after setting a channel path
offline. Also make sure to generate a fake irb if the device
driver issues an I/O request after being notified of the killed
I/O and clear residual information from the irb before trying to
start the delayed verification.Signed-off-by: Cornelia Huck

Trying to set a DASD root device online can fail under some circumstances
with the message "Read configuration data returned error -5". The cause
is that read configuration data incorrectly aborts with -EIO when it
encounters a temporary busy condition at a storage server.
Perform retry when encountering temporary busy conditions.Signed-off-by: Peter Oberparleiter

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
