Subject: [PATCH AUTOSEL 6.3 07/17] arm64/hyperv: Use CPUHP_AP_HYPERV_ONLINE state to fix CPU online sequencing
Date: Thu, 29 Jun 2023 15:00:36 -0400 [thread overview]
Message-ID: <20230629190049.907558-7-sashal@kernel.org> (raw)
In-Reply-To: <20230629190049.907558-1-sashal@kernel.org>
From: Michael Kelley <mikelley@microsoft.com>
[ Upstream commit 52ae076c3a9b366b6fa9f7c7e67aed8b28716ed9 ]
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.
