[PATCH v5 00/19] s390x: Add Full Boot Order Support

[jrossi]

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

changes v4 -> v5:
- Fix a bug with per-deice loadparm support:
    The machine loadparm is no longer overwritten by device values, which now
    allows an empty machine loadparm to propagate to later devices even if
    the primary boot device set an initial loadparm
- Fix two instances where changes were squashed into wrong patch
- Fix an instance where NULL_BLOCK_NR was returned instead of ERROR_BLOCK_NR
- Fix an instance of logical AND being used instead of bitwise AND
- Standardize all error values to be negative in all device type paths
- Minor stylistic changes and code simplification


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
