From 52ae076c3a9b366b6fa9f7c7e67aed8b28716ed9 Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Tue, 23 May 2023 10:14:22 -0700 Subject: [PATCH] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing 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.
