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

From: Michael Kelley
Date: Fri May 19 2023 - 10:34:39 EST


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