Subject: linux-next: build failure after merge of the hyperv tree

---

Hi all,

After merging the hyperv tree, today's linux-next build (i386 defconfig)
failed like this:

arch/x86/kernel/cpu/mshyperv.c:355:5: error: no previous prototype for 'hv_get_hypervisor_version' [-Werror=missing-prototypes]
355 | int hv_get_hypervisor_version(union hv_hypervisor_version_info *info)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

1634df06ea12 ("mshyperv: Introduce hv_get_hypervisor_version function")

I have reverted that commit for today.

Cheers,
Stephen Rothwell

We noticed this as well. A fix has been sent out. I will update the tree
shortly.

Thanks,
Wei.
