These two patches result in warnings (that get upgraded to errors with
CONFIG_WERROR=y / W=e) on arm64:
$ make -skj"$(nproc)" ARCH=arm64 CROSS_COMPILE=aarch64-linux- clean defconfig
$ scripts/config -e HYPERV -e MSHV_ROOT
$ make -skj"$(nproc)" ARCH=arm64 CROSS_COMPILE=aarch64-linux- olddefconfig drivers/hv/mshv_common.o
drivers/hv/mshv_common.c:210:6: warning: no previous prototype for 'hv_sleep_notifiers_register' [-Wmissing-prototypes]
210 | void hv_sleep_notifiers_register(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/hv/mshv_common.c:224:6: warning: no previous prototype for 'hv_machine_power_off' [-Wmissing-prototypes]
224 | void hv_machine_power_off(void)
| ^~~~~~~~~~~~~~~~~~~~
The prototypes for these functions are only available for x86.
Cheers,
Nathan
