Could you rebase it to current trunk.
You should probably create a subtarget like target/linux/x86/kvm_guest/
for Hyper-V and activate there CONFIG_HYPERV=y and CONFIG_HYPERV_STORAGE=y

Why do you build CONFIG_HYPERV into the kernel? This should be build as
a module, because this package will be build on all x86 kernels.

You should not crate a OpenWrt kernel module package which build stuff
into the kernel image.
