Paolo, Radim, here is part1 of the s390 patches for 4.8. This time a big chunk - with more to come in part2. All base s390 change have the proper ack of the maintainers (or are kvm specific code in a common file). There is one patch with cc stable (40/52 s390/mm: don't drop errors in get_guest_storage_key) - which in theory would make it more of a candidate for master instead of next. As we replace that code with a following patch anyway I want to avoid yet another merge conflict as this pull request already has two simple things against the s390-next tree. The following changes since commit dca4d728773a2f48e999c8617524bbf8dee4807f: kvm/x86: remove unnecessary header file inclusion (2016-06-03 15:28:19 +0200) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git tags/kvm-s390-next-4.8-1 for you to fetch changes up to a7e19ab55ffdd82f1a8d12694b9a0c0beeef534c: KVM: s390: handle missing storage-key facility (2016-06-10 12:07:31 +0200) ---------------------------------------------------------------- KVM: s390: Features and fixes for 4.8 part1 Four bigger things: 1. The implementation of the STHYI opcode in the kernel. This is used in libraries like qclib [1] to provide enough information for a capacity and usage based software licence pricing. The STHYI content is defined by the related z/VM documentation [2]. Its data can be composed by accessing several other interfaces provided by LPAR or the machine. This information is partially sensitive or root-only so the kernel does the necessary filtering. 2. Preparation for nested virtualization (VSIE). KVM should query the proper sclp interfaces for the availability of some features before using it. In the past we have been sloppy and simply assumed that several features are available. With this we should be able to handle most cases of a missing feature. 3. CPU model interfaces extended by some additional features that are not covered by a facility bit in STFLE. For example all the crypto instructions of the coprocessor provide a query function. As reality tends to be more complex (e.g. export regulations might block some algorithms) we have to provide additional interfaces to query or set these non-stfle features. 4. Several fixes and changes detected and fixed when doing 1-3. All features change base s390 code. All relevant patches have an ACK from the s390 or component maintainers. The next pull request for 4.8 (part2) will contain the implementation of VSIE.
