[PATCH v2 0/3] Early boot self tests for RCU

[Pranith Kumar]

Hi Paul,

Please find v2 of the RCU early boot tests. For now
all we do in these tests are enqueue test callbacks and check if they are being
invoked or not.

I was able to reproduce the hang which Amit reported after reverting the fix. So
this should catch such errors if they occur in the future.

I enabled the selftests in a few rcutorture configurations.

Thanks!
