[PATCH v1 0/7] KVM: s390: More memory management fixes

Posted by Claudio Imbrenda 2 weeks, 5 days ago

This series fixes some bugs that have been recently introduced with the
big gmap rewrite.

are more general. The last patch fixes an issue introduced last year.

  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
