This patch series plans to add support for running nested Microsoft
Hypervisor. In case of nested Microsoft Hypervisor there are few
privileged hypercalls which need to go L0 Hypervisor instead of L1
Hypervisor. This patches series basically identifies such hypercalls and
replace them with nested hypercalls.

Jinank Jain (5):
x86/hyperv: Add support for detecting nested hypervisor
I see `__weak hv_nested` in this patch.

I guess this version has fixed ARM64 build?

It is fixed in v4 of the patch series.
