This is an actual KSM test.
It allows to test merging resp splitting the pages in serial, parallel
or both. Also you can specify an overcommit ratio for KSM overcommit
testing.
We were forced to destroy all previous defined vms and to create them
inside the test (similar to stress_boot),

The use of __pa() to calculate the address of a C-visible symbol
is wrong, and can lead to unpredictable results. See arch/x86/include/asm/page.h
for details.
It should be replaced with __pa_symbol(), that does the correct math here,
by taking relocations into account.

These are now wrong, since handle_invalid_exit() is called with interrupts

Yes.

One way to share the effort is to make vmdq queues available as normal
kernel interfaces. It would take quite a bit of work, but the end
result is that no other components need to be change, and it makes vmdq
useful outside kvm. It also greatly reduces the amount of integration
work needed
