I can confirm that this series (probably this patch) breaks the
following scenario:
qemu-system-x86_64 (qemu trunk, emulation mode)
linux (kvm.git) with kvm-amd + kvm-userspace
linux (the same kvm.git)
The second-level guest hangs in the mid of its boot, maybe no longer
receiving some or any interrupt.
So this patch may either expose a bug in the svm emulation of qemu or
comes with a subtle regression that only triggers due to qemu's timing.
This needs to be understood. Gleb, any progress on reproducing it on
your side?
