Hi all,

After merging the hyperv tree, today's linux-next build (x86 allmodconfig)
failed like this:

/tmp/next/build/arch/x86/kernel/x86_init.c:36:12: error: static declaration of 'set_rtc_noop' follows non-static declaration
36 | static int set_rtc_noop(const struct timespec64 *now) { return -EINVAL; }

Caused by commit

25dcc7316ef7def25c ("x86/init: Make get/set_rtc_noop() public")

I will use the hyperv tree from yesterday instead.
