Subject: [PATCH v1 0/7] KVM: s390: More memory management fixes
Date: Wed, 18 Mar 2026 15:08:46 +0100 [thread overview]
Message-ID: <20260318140853.119460-1-imbrenda@linux.ibm.com> (raw)
This series fixes some bugs that have been recently introduced with the
big gmap rewrite.
Most of the fixes are related to vSIE (nested guests), although some
are more general. The last patch fixes an issue introduced last year.
Claudio Imbrenda (7):
KVM: s390: Remove non-atomic dat_crstep_xchg()
KVM: s390: vsie: Fix check for pre-existing shadow mapping
KVM: s390: Fix gmap_link()
KVM: s390: vsie: Fix refcount overflow for shadow gmaps
KVM: s390: vsie: Fix unshadowing while shadowing
KVM: s390: vsie: Fix off-by-one when protecting guest page tables
KVM: s390: Fix KVM_S390_VCPU_FAULT ioctl
