Linus Torvalds 9a0f53e0cf CSD lock commits for v6.7 ...

This series adds a kernel boot parameter that causes the kernel to
 panic if one of the call_smp_function() APIs is stalled for more than
 the specified duration.  This is useful in deployments in which a clean
 panic is preferable to an indefinite stall.
