[GIT PULL 00/13] KVM: s390: Changes for 5.18 part1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Paolo,

first part of the s390 parts of KVM for 5.18. This is on top of the fix
that went into Linus tree, so it will move kvm/next to something between
rc3 and rc4.

I added 2 later fixups for the storage key patches on top. Let me know if
you prefer them folded in.

We might do a 2nd pull request later on depending on timing, review and
other constraints
with
- rewritten selftest for memop
- ultravisor device (could also go via s390 tree)
- parts/all of Claudios lazy destroy
- parts/all of PCI passthru (could be later and might go via s390 tree as
  well via a topic branch)
- followup to guest entry/exit work if we find a small solution
- adapter interruption virtualization facility for secure guests

The following changes since commit 09a93c1df3eafa43bcdfd7bf837c574911f12f55:
