[SRU][D][PATCH 0/1] Fix CPU soft lockup during eBPF workloads

A CPU soft-lockup is reported by Google on GKE kernels. Google also identified the fix and confirmed that it resolves the lockup.
I'm proposing to include the fix in the master 5.0 kernel instead of just the gke-5.0 kernel.

This has been boot-tested by myself and confirmed by Google to fix the issue described in the SalesForce ticket.
