Subject: [PATCH v2 2/2] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing
Date: Tue, 23 May 2023 10:14:22 -0700 [thread overview]
Message-ID: <1684862062-51576-2-git-send-email-mikelley@microsoft.com> (raw)
In-Reply-To: <1684862062-51576-1-git-send-email-mikelley@microsoft.com>
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.
