X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=afa538f0a171f479f6b3a9718a8608ef471ebd77;p=deliverable%2Flinux.git Merge tag 'kvm-s390-20140516' of git://git./linux/kernel/git/kvms390/linux into kvm-next 1. Correct locking for lazy storage key handling A test loop with multiple CPUs triggered a race in the lazy storage key handling as introduced by commit 934bc131efc3e4be6a52f7dd6c4dbf (KVM: s390: Allow skeys to be enabled for the current process). This race should not happen with Linux guests, but let's fix it anyway. Patch touches !/kvm/ code, but is from the s390 maintainer. 2. Better handling of broken guests If we detect a program check loop we stop the guest instead of wasting CPU cycles. 3. Better handling on MVPG emulation The move page handling is improved to be architecturally correct. 3. Trace point rework Let's rework the kvm trace points to have a common header file (for later perf usage) and provided a table based instruction decoder. 4. Interpretive execution of SIGP external call Let the hardware handle most cases of SIGP external call (IPI) and wire up the fixup code for the corner cases. 5. Initial preparations for the IBC facility Prepare the code to handle instruction blocking --- afa538f0a171f479f6b3a9718a8608ef471ebd77
