[PATCH v2 0/9] KVM: s390: And then... even more fixes again

Another round of mostly unrelated misc fixes.

Mostly small and/or unlikely issues, but they needed to be addressed.

v1->v2:
* Use the srcu only around kvm_s390_inject_vcpu()
* Wildly simplify the third patch: introduce gisa_test_ipm_gisc() and
  use it in get_all_floating_irqs() instead of gisa_tac_ipm_gisc()
* Use set_page_dirty() instead of set_page_dirty_lock(). In all
  scenarios we are holding an extra reference to the page, we don't
  need to also lock. Also move things around a little to avoid races.
* Fix return value of kvm_arch_prepare_memory_region()
* Fix return value being overwritten in patch 8
* Drop patches 6 and 7, they need more thought
