Subject[PATCH v2 0/4] KVM: x86: get CPL from SS.DPL
Date
Another day, another CPL patch...

It turns out that the simple approach of getting CPL from SS.DPL
broke x86/taskswitch2.flat. To fix that, already "imagine" that the
CPL is CS.RPL, or 3 for VM86 tasks, while loading segment descriptors
during task switches. This removes the hack where task switches call
kvm_set_rflags to override the VM flag (patch 2).

While at it, add a new privilege test during task switches that is
missing.

Patch 4 is the same as before.

Paolo Bonzini (4):
KVM: x86: use new CS.RPL as CPL during task switch
KVM: x86: drop set_rflags callback
KVM: x86: check CS.DPL against RPL during task switch
KVM: x86: get CPL from SS.DPL
