Subject: [PATCH 2/2] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing
Date: Fri, 19 May 2023 07:33:52 -0700 [thread overview]
Message-ID: <1684506832-41392-2-git-send-email-mikelley@microsoft.com> (raw)
In-Reply-To: <1684506832-41392-1-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 use new state
for Hyper-V initialization so that hyperv_pcpu_input_arg is allocated
early enough.
