I swear I would have sent it the same to Linus! The main cause for this is that I was on vacation until two weeks ago and it took a while to sort all the pending patches between 4.19 and 4.20, test them and so on. It's mostly small bugfixes and cleanups, mostly around x86 nested virtualization. One important change, not related to nested virtualization, is that the ability for the guest kernel to trap CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now masked by default. This is because the feature is detected through an MSR; a very bad idea that Intel seems to like more and more. Some applications choke if the other fields of that MSR are not initialized as on real hardware, hence we have to disable the whole MSR by default, as was the case before Linux 4.12. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJbpPo1AAoJEL/70l94x66DdxgH/is0qe6ZBtzb6Qc0W+8mHHD7 nxIkWAs2V5NsouJ750YwRQ+0Ym407+wlNt30acdBUEoXhrnA5/TvyGq999XvCL96 upWEIxpIgbvTMX/e2nLhe4wQdhsboUK4r0/B9IFgVFYrdCt5uRXjB2G4ewxcqxL/ GxxqrAKhaRsbQG9Xv0Fw5Vohh/Ls6fQDJcyuY1EBnbMpVenq2QDLI6cOAPXncyFb uLN6ov4GNCWIPckwxejri5XhZesUOsafrmn48sApShh4T6TrisrdtSYdzl+DGza+ j5vhIEwdFO5kulZ3viuhqKJOnS2+F6wvfZ75IKT0tEKeU2bi+ifGDyGRefSF6Q0= =YXLw -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Paolo writes: "It's mostly small bugfixes and cleanups, mostly around x86 nested virtualization.
