[PATCH v7 0/2] target/s390x: Implement the MVPG condition-code-option bit

[David Hildenbrand <david@redhat.com>]

Based on work from Richard and Thomas.

v6 -> v7:
- "target/s390x: Implement the MVPG condition-code-option bit"
-- Fix PGM_PROTECTION for QEMU_USER_ONLY (overridden by patch #2)

v5 -> v6:
- "target/s390x: Implement the MVPG condition-code-option bit"
-- Better handle CONFIG_USER_ONLY
-- Factor handling out into s390_probe_access().
- "target/s390x: Store r1/r2 for page-translation exceptions during MVPG"
-- Store tec only for !PGM_ADDRESSING

v4 -> v5:
- Don't realy on TLB_INVALID_MASK
-- Check against tlb_fill_exc and return the exception right away
- Handle !CONFIG_USER_ONLY
-- Check against haddr
-- Properly store vaddr to env->__excp_addr and return PGM_ADDRESSING
- Exclude tlb_fill_tec/tlb_fill_exc for CONFIG_USER_ONLY
- While at it, tackle r1/r2 indication as well

KVM unit tests continue working as expected.
