[21.04 FEAT] NVMe IPL Load Normal support - s390-tools part

[bugproxy]

Re-IPL for NVMe is currently done by using diag 308 with the "Load Clear" subcode, which means that all memory will be cleared.
This can increase re-IPL duration considerably on very large machines.

For list-directed IPL like NVMe or FCP IPL, a "Load Normal" subcode was introduced with z14. The "Load Normal" diag 308 subcode allows to re-IPL without clearing memory.

This feature adds kernel and s390-tools support for a new "clear" sysfs attribute in /sys/firmware/reipl/nvme, which can be set to either "0" or "1" to disable or enable re-IPL with memory clearing. The default value is "0", which disables memory clearing.

Feature request for s390-tools contribution.
Target s390-tools >=2.15, therefore backport information required.

Setting to Incomplete until backport is shared.

The feature was made available with s390tools 2.15.0.
Therefore integration into 21.04 by package upgrade.

[Launchpad Janitor (janitor)]

This bug was fixed in the package s390-tools - 2.15.1-0ubuntu2

---------------
s390-tools (2.15.1-0ubuntu2) hirsute; urgency=medium

  * Package libekmfweb library.
  * Do not use /usr/lib64 prefix.

s390-tools (2.15.1-0ubuntu1) hirsute; urgency=medium

  * New upstream release. LP: #1902865, LP: #1902047, LP: #1892824, LP: #1887920, LP: #1887806

    are desired in both packages that ship hooks.

s390-tools (2.14.0-2ubuntu1) hirsute; urgency=medium

  * Merge from Debian unstable (LP: #1903688). Remaining changes:
    - lower priority to optional
    - add libsnmp-dev, libglib2.0-dev build-deps
    - add support for signed zipl
    - use z Systems branding in descriptions
    - package cpuplugd, osasnmpd, statd, zkey
    - drop ziomon package, shipped in the main package
    - ship zdev in udeb
    - update copyright file
    - fix kernel installer script integration, to skip calling zipl without initrd
    - load monwriter kernel module for mon_statd/mon_fsstatd
    - do not run dumpconf in lxc
    - ziomon change exit code to 0 for version and help
    - add zkey initramfs hook
    - change zkey default back to argon2i
    - drop patch that disables building osasnmpd
    - drop udevadm-path.patch to init script, systemd units are used instead
    - enable hardening
    - enable initramfs & dracut integration
    - setup users/groups for mon_*, iucvterm, zkey
    - install more utilities and zdev initramfs integration
    - setup crashkernel integration
  * Update debian/not-installed file for additional files in debian/tmp
  * debian/rules:
    - drop unneeded "--parallel --with systemd" dh args
    - clean zipl/boot/.stage*.d files
    - avoid dh_installinitramfs to install additional triggers
  * s390-tools.docs: ship CHANGELOG.md (as Debian does)
