Linus Torvalds e813e65038 ARM: Cleanups and corner case fixes ... PPC: Bugfixes x86: * Support for mapping DAX areas with large nested page table entries. * Cleanups and bugfixes here too. A particularly important one is a fix for FPU load when the thread has TIF_NEED_FPU_LOAD. There is also a race condition which could be used in guest userspace to exploit the guest kernel, for which the embargo expired today. * Fast path for IPI delivery vmexits, shaving about 200 clock cycles from IPI latency. * Protect against "Spectre-v1/L1TF" (bring data in the cache via speculative out of bound accesses, use L1TF on the sibling hyperthread to read it), which unfortunately is an even bigger whack-a-mole game than SpectreV1. Sean continues his mission to rewrite KVM. In addition to a sizable number of x86 patches, this time he contributed a pretty large refactoring of vCPU creation that affects all architectures but should not have any visible effect. s390 will come next week together with some more x86 patches. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJeMxtCAAoJEL/70l94x66DQxIIAJv9hMmXLQHGFnUMskjGErR6 DCLSC0YRdRMwE50CerblyJtGsMwGsPyHZwvZxoAceKJ9w0Yay9cyaoJ87ItBgHoY ce0HrqIUYqRSJ/F8WH2lSzkzMBr839rcmqw8p1tt4D5DIsYnxHGWwRaaP+5M/1KQ YKFu3Hea4L00U339iIuDkuA+xgz92LIbsn38svv5fxHhPAyWza0rDEYHNgzMKuoF IakLf5+RrBFAh6ZuhYWQQ44uxjb+uQa9pVmcqYzzTd5t1g4PV5uXtlJKesHoAvik Eba8IEUJn+HgQJjhp3YxQYuLeWOwRF3bwOiZ578MlJ4OPfYXMtbdlqCQANHOcGk= =H/q1 -----END PGP SIGNATURE----- Merge tag 'kvm-5.6-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "This is the first batch of KVM changes.
