[qemu-s390x] [PATCH v1 0/3] s390x/sclp: 64 bit event masks |

Until 67915de9f0383ccf4a ("s390x/event-facility: variable-length event masks")
we only supported 32bit sclp event masks, even though the archiecture
allows the guests to set up sclp event masks up to 1021 bytes in length.
With that patch the behaviour was almost compliant, but some issues were
still remaining, in particular regarding the handling of selective reads
and migration.
This patchset fixes migration and the handling of selective reads, and
puts in place the support for 64-bit sclp event masks internally.
A new property of the sclp-event device switches between the 32bit masks
and the compliant behaviour. The property is bound to the machine
version, so older machines keep the old broken behaviour, allowing for
migration, but the default is the compliant implementation.
Fixes: 67915de9f0383ccf4a ("s390x/event-facility: variable-length event masks")
Claudio Imbrenda (3):
s390x/sclp: proper support of larger send and receive masks
s390x/sclp: clean up sclp masks
s390x/sclp: extend SCLP event masks to 64 bits
