Found this today:

In file included from arch/x86/kernel/sev.c:519:
At top level:
arch/x86/kernel/sev-shared.c:167:24: warning: ‘sev_es_ghcb_terminate’ defined but not used [-Wunused-function]
167 | static void __noreturn sev_es_ghcb_terminate(struct ghcb *ghcb, unsigned int set,
| ^~~~~~~~~~~~~~~~~~~~~

I am wondering why I did not get this error in my build testing.

sev-shared.c gets included from two files boot/compressed/sev.c and kernel/sev.c, sev_es_ghcb_terminate()
has only one user. I will move helper function to boot/compressed/sev.c and send an updated version.
