[PATCH v2 2/2] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing

From: Michael Kelley
Date: Tue May 23 2023 - 13:32:54 EST


State CPUHP_AP_HYPERV_ONLINE has been introduced to correctly sequence the
initialization of hyperv_pcpu_input_arg. Use this new state for Hyper-V
initialization so that hyperv_pcpu_input_arg is allocated early enough.
