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

Hi all,
After merging the hyperv tree, today's linux-next build (x86_64
allmodconfig) failed like this:
arch/x86/kvm/hyperv.c: In function 'kvm_vcpu_ioctl_get_hv_cpuid':
arch/x86/kvm/hyperv.c:2020:16: error: 'HV_X64_DEBUGGING' undeclared (first use in this function); did you mean 'HV_DEBUGGING'?
2020 | ent->ebx |= HV_X64_DEBUGGING;
| ^~~~~~~~~~~~~~~~
| HV_DEBUGGING
arch/x86/kvm/hyperv.c:2020:16: note: each undeclared identifier is reported only once for each function it appears in
Caused by commit
c55a844f46f9 ("x86/hyperv: Split hyperv-tlfs.h into arch dependent and independent files")
interacting with commit
f97f5a56f597 ("x86/kvm/hyper-v: Add support for synthetic debugger interface")
from the kvm tree.
I have applied this patch for today:
