When building the out-of-tree drivers with virtualization support disabled, symbols for some of the virtualization functions are not found ... nvgpu: Unknown symbol tegra_hv_mempool_unreserve (err -2) nvgpu: Unknown symbol is_tegra_hypervisor_mode (err -2) nvgpu: Unknown symbol tegra_hv_mempool_reserve (err -2) nvhost_pva: Unknown symbol is_tegra_hypervisor_mode (err -2) mc_utils: Unknown symbol is_tegra_hypervisor_mode (err -2) mc_utils: Unknown symbol is_tegra_hypervisor_mode (err -2) Update the hv-ivc.h header to ensure that these function stubs are defined when virtualization support is disabled and only build the hv-ivc driver if virtualization is enabled. Finally, move populating the ccflags to the top-level Makefile and use the subdir-ccflags directive to ensure the ccflags are passed to all sub-directories.
