I check the situation in the different git trees (upstream and the ones for the relevant Ubuntu releases) and the outcome is:
The commit a3e03bc1368c ("KVM: s390: index kvm->arch.idle_mask by vcpu_idx") is upstream since v5.15-rc1, hence jammy does not need to be patched, since it's target kernel version is 5.15, hence setting the 'affects jammy' entry to Fix Released. I found the commit (here with hash 3cde6b00247a) in impish master. It landed there based on https://bugs.launchpad.net/bugs/1946247 "Impish update: v5.13.17 upstream stable release" and is tagged with Ubuntu-5.13.0-21.21 and since there is 5.13.0.21.32 in impish-updates, the patch is already rolled out for impish, hence marking the 'affects impish' entry as Fix Released. I also found the commit (here with hash 8f355838f663) in hirsute master. It landed there based on https://bugs.launchpad.net/bugs/1946788 "Hirsute update: upstream stable patchset 2021-10-12" and is tagged with Ubuntu-5.11.0-39.43 (and newer) and since there is 5.11.0.40.41 in hirsute-updates, the patch is already rolled out for hirsute, hence marking the 'affects hirsute' entry as Fix Released. And finally I also found the commit (here with hash b8265c7188e4) in focal master-next. It landed there based on https://bugs.launchpad.net/bugs/1946024 "Focal update: v5.4.146 upstream stable release" and is tagged with Ubuntu-5.4.0-90.101 and since there is 5.4.0.90.94 in focal-updates (btw. the last digit can be ignored), the patch is already rolled out for focal, hence marking the 'affects focal' entry as Fix Released, too. (I like it is fixes were marked for upstream stable updates :-) ** Also affects: linux (Ubuntu Impish) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Assignee: Skipper Bug Screeners (skipper-screen-team) Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: ubuntu-z-systems Importance: Undecided Status: New ** Changed in: linux (Ubuntu Jammy) Status: New => Fix Released ** Changed in: linux (Ubuntu Impish) Status: New => Fix Released ** Changed in: linux (Ubuntu Hirsute) Status: New => Fix Released ** Changed in: linux (Ubuntu Focal) Status: New => Fix Committed ** Changed in: linux (Ubuntu Focal) Status: Fix Committed => Fix Released ** Changed in: ubuntu-z-systems Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951109 Title: [UBUNTU 20.04] kvm: floating interrupts may get stuck To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1951109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
