Should we simply revert the patch, maybe also 9fe573d539a8 ("KVM: nVMX: reset cache/shadows when switching loaded VMCS")
Both of them are from one big patchset: https://patchwork.kernel.org/cover/10616179/
Revert both patches recover the regression I see on kvm-unit-tests.
Greg already included the patches that the bot missed, so it's okay.

Sorry, I think I gave wrong information initially, it's 9fe573d539a8 ("KVM: nVMX: reset cache/shadows when switching loaded VMCS") which caused regression.
Should we revert or there's following up fix we should backport?
Hmm, let's revert all four. This one, the two follow-ups and 9fe573d539a8.
4? I see three patches here, the 2 follow-up patches that I applied to the queue, and the "original" backport of b7031fd40fcc ("KVM: nVMX: reset cache/shadows when switching loaded VMCS") which showed up in the 4.14.157 and 4.19.87 kernels.
The fourth is commit 9fe573d539a8 ("KVM: nVMX: reset cache/shadows when switching loaded VMCS"), which was also autoselected.
Ah, thanks, I missed that. Should all now be fixed up here, and in the 4.14.y tree.
