[PATCH] x86/hyperv: Use per cpu initial stack for vtl context

2024-02-01 Thread Saurabh Sengar
Currently, the secondary vCPUs in Hyper-V VTL context lack support for parallel startup. Therefore, relying on the single initial_stack fetched from the current task structure suffices for all vCPUs. However, common initial_stack risks stack corruption when parallel startup is enabled. In order to
