[PATCH v3 0/4] KVM: s390: Misc bugfixes for 7.4

[Claudio Imbrenda <imbrenda@linux.ibm.com>]

Misc bugfixes.

Some Fixes tags are approximate, since the bugs arise from slow changes
behind the scenes in the kernel, and not from an actual bug at the moment
of the introduction of the original code.

v2->v3:
* remove all non-bugfix patches
* rebase onto master

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 (4):
  KVM: s390: Fix UCONTROL inconsistencies
  KVM: s390: Move some skey functions to headers
  KVM: s390: Improve unmapping of large ranges
  KVM: s390: vsie: Fix pinning using the wrong flag
