Subject[PATCH 0/2] kvm: add selftests for API testing
Date
This is an initial reduced version of the self tests that Google contributed,
with the harness reduced from 12000 to 6000 lines thanks to my trusty chainsaw
(model "d%").

Rather than including them in kvm-unit-tests, I chose to place these tests
into linux.git, which of course had the side effect that the code had to be
cleaned up a bit to look more like Linux.

In particular a lot of changes went into lib/sparsebit.c; I don't have
a testsuite for that so I chose to fuzz it instead. Turns out there were
no bugs introduced by the cleanups, which actually did surprise me, but
fuzzing did find some bugs in the driver instead so I think it can be
trusted. :)

For now there are two simple tests noly. I'm leaving out the VMX test
because nested is still not enabled by default and thus the test fails
with a default configuration. In any case, the idea is to first change
them to use more of the kselftest infrastructure, and then add more
tests.
