[PATCH v4 00/19] s390x: Add Full Boot Order Support

[jrossi]

From: Jared Rossi <jrossi@linux.ibm.com>

changes v3 -> v4:
- Ensure signed-ness of return values is appropriate
- Add missing newline character in replacements of sclp_print_int()
- Add a missing return in a SCSI error path
- Restore break that was incorrectly removed for Virtio CU devices
- Remove an extra/early return that caused probing to end early
- Convert "good" device to scsi-cd in a cdrom-test for better coverage
- Minor stylistic clean-ups and variable name clarifications

changes v2 -> v3:

- Fix return code mismatch in ISO IPL path
- Introduce a new RC for loading ECKD segments rather than rely on block 0
- Fix bug causing false negative in some SCSI device error cases
- Terminate entire IPL on bad PBT instead of trying next device
- Simplify routine for building IPLB chain
- Restore device probing
- Add qtests
- Minor stylistic clean-ups and comment clarifications
