Subjectlinux-next: build failure after merge of the kvm tree
Hi all,

After merging the kvm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

arch/x86/kvm/cpuid.c: In function 'kvm_update_cpuid':
arch/x86/kvm/cpuid.c:98:2: error: implicit declaration of function 'use_eager_fpu' [-Werror=implicit-function-declaration]
vcpu->arch.eager_fpu = use_eager_fpu() || guest_cpuid_has_mpx(vcpu);

Caused by a bad automatic merge resolution which didn't add the
includes of one of its parents.

I added the following merge fix patch:
