Subject: [PATCH v2 00/10] KVM: s390: Misc bugfixes and improvements for 7.4
Date: Fri, 23 Oct 2026 17:55:21 +0200	[thread overview]
Message-ID: <20261023155531.206113-1-imbrenda@linux.ibm.com> (raw)

Misc bugfixes and improvements.

Some are preparations for future patches, some are preventive fixes for
mostly theoretical issues, some are quality of life improvement (mostly
for the maintainers).

v1->v2:
* add "memory" clobber to idte_crste()
* remove superflouos gpa parameter for unpin_scb()
* clear the zero bit in the PGSTE when unmapping, add missing barrier

The remaining issues raised by sashiko in v1 are false positives.

Claudio Imbrenda (10):
  KVM: s390: Move some skey functions to headers
  KVM: s390: Refactor and improve DAT tables handling
  KVM: s390: Move prefix marker from PGSTEs to PTEs
  KVM: s390: Automatically enable storage keys for UCONTROL VMs
  KVM: s390: Replace ASCE usage with a struct with more flags
  KVM: s390: Rework some helper functions
  KVM: s390: Fix UCONTROL inconsistencies
  KVM: s390: Improve unmapping of large ranges
  KVM: s390: vsie: Fix pinning using the wrong flag
  KVM: s390: Enable 1M pages by default
