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

[Pranith Kumar]

Hi Paul,

Please find the following patches which enable 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!
