The KVM indirect vectors support is a little complicated. Different CPUs
may use different exception vectors for KVM that are generated at boot.
Adding new instructions involves checking all the possible combinations
do the right thing.
To make changes here easier to review lets state what we expect of the
preamble:
1. The first vector run, must always run the preamble.
2. Patching the head or tail of the vector shouldn't remove
preamble instructions.
Today, this is easy as we only have one instruction in the preamble.
Change the unpatched tail of the indirect vector so that it always
runs this, regardless of patching.
