Saurabh Sengar 3d6af30f17 x86/hyperv: Use per cpu initial stack for vtl context ... [ Upstream commit 2b4b90e053a29057fb05ba81acce26bddce8d404 ] Currently, the secondary CPUs 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 facilitate parallel startup, use the initial_stack from the per CPU idle thread instead of the current task.
