Subject: [PATCH 12/14] fix multipath device detection in ziomon
Description: ziomon: Fix multipath device detection
Symptom: Running ziomon with a valid multipath device like
/dev/mapper/36005076303ffc56200000000000010cc
fails with "ziomon: The following devices do not seem
to exist:".
Problem: The output from multipath -l is not appended correctly to
the mp_arr array.
Solution: Properly initializing mp_arr to an empty array fixes this.

Subject: [PATCH 13/14] zipl - handle status during ipl
Description: zipl: handle status during ipl
Symptom: You encounter an error during IPL with "disabled wait" message.
Problem: During the IPL sequence the subchannel of the IPL device has
to be enabled. If there is a status pending or busy condition
on the subchannel the IPL code abborts the IPL and goes into
disabled wait.
Solution: To resolve the problem the IPL code accepts the status pending
or busy condition on the subchannel and does up to 256 retries.

Subject: [PATCH 14/14] dasdview, fdasd: fix floating point error for unformatted devices
When executed on an unformatted device the tools dasdview and fdasd
will end with an floating point exception error.
The reason for the error lies in the fact that we cannot rely on the
HDIO_GETGEO ioctl to report a correct number of cylinders and so we
compute the number of cylinders from the device size. However,
for unformatted devices the device size is zero and thus our
computation ends with a floating point exception.
To solve this issue read the correct number of cylinders from
the DASD device characteristics, which can be found in the data
returned by the BIODASDINFO ioctl.
