[PATCH v3 0/8] KVM: s390: Even more misc fixes

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

A few fixes that had been dropped from previous series due to still
having issues, plus a few new fixes.

v2->v3:
* Rebase on master
* Reworked first patch to use scoped_guard() more, and restrict the
  scope of the srcu so that it excludes the page pinning
* Add missing const to parameter "old" of kvm_s390_update_cmma_dirty()
* Fix potential infinite loop in dat_get_storage_key() and
  dat_reset_reference_bit()
* Fix potential race in _destroy_pages_crste()

v1->v2:
* Fix racy usage of sg->parent in patch 2
* Fix wrong number of arguments for dat_delete_slot() in patch 3
* Restrict srcu usage to the bare minimum necessary to avoid potentially
  triggering page faults in the guest while holding the srcu
* Fix races also in other skey functions
