...------------------ From: Juergen Gross <jgross at suse.com> commit f72e38e8ec8869ac0ba5a75d7d2f897d98a1454e upstream. Instead of x86_hyper being either NULL on bare metal or a pointer to a struct hypervisor_x86 in case of the kernel running as a guest merge the struct into x86_platform and x86_init. This will remove the need for wrappers making it hard to find out what is being called. With dummy functions added for all callbacks testing for a NULL function pointer can be removed, too.
