Subject: Drivers: hv: Enable Hyper-V code to be built on ARM64
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7aff79e297ee1aa0126924921fd87a4ae59d2467;p=linux.git

Drivers: hv: Enable Hyper-V code to be built on ARM64

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.
