Subject: [PATCH v12 5/5] Drivers: hv: Enable Hyper-V code to be built on ARM64
Date: Wed,  4 Aug 2021 08:52:39 -0700	[thread overview]
Message-ID: <1628092359-61351-6-git-send-email-mikelley@microsoft.com> (raw)
In-Reply-To: <1628092359-61351-1-git-send-email-mikelley@microsoft.com>

Update drivers/hv/Kconfig so CONFIG_HYPERV can be selected on
ARM64, causing the Hyper-V specific code to be built. Exclude the
Hyper-V enlightened clocks/timers code from being built for ARM64.
