Here's a respin of the uncontroversial s390x patches for 2.4.
Changes from the last posting:
- headers update is now against 4.1
- dropped Thomas' patch removing the switch_amode message, added
a patch giving more up-to-date hints on failure instead
If there are no objections, I plan to send a pull request later this
week.
Alexander Yarygin (1):
s390x/kvm: Support access register mode for KVM_S390_MEM_OP ioctl
Cornelia Huck (6):
virtio-ccw: sort into categories
s390-virtio: sort into categories
sclp: sort into categories
s390x/ipl: sort into categories
linux-headers: update
kvm: better advice for failed s390x startup
Ekaterina Tumanova (1):
s390x/kvm: Put vm name, extended name and UUID into STSI322 SYSIB
Thomas Huth (2):
s390x/mmu: Use access type definitions instead of magic values
s390x/mmu: Use ioctl for reading and writing from/to guest memory

This patch allows userspace to intercept execution, and fill in the values, that are known to qemu: machine name (8 chars), extended machine name (256 chars), extended machine name encoding (equals 2 for UTF-8) and UUID. STSI322 qemu handler also finds a highest virtualization level in level-3 virtualization stack that doesn't support Extended Names (Ext Name delimiter) and propagates zero Ext Name to all levels below, because this level is not capable of managing Extended Names of lower levels.

In this mode the address space is specified by values of the access registers. The effective address-space-control element is obtained from the result of the access register translation. See the "Access-Register Introduction" section of the chapter 5 "Program Execution" in "Principles of Operations" for more details. When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must know which access register number to use for address translation. This patch does several things: - add new parameter 'uint8_t ar' to that function - decode ar number from intercepted instructions - pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it to the KVM_S390_MEM_OP ioctl.
