Pure luck :-\

gcc cmdline is:

gcc -Wp,-MMD,arch/x86/boot/startup/.sev-startup.o.d -nostdinc
-I./arch/x86/include...

so the include path becomes:

# 1 "./arch/x86/include/../coco/sev/internal.h" 1

which is

$ readlink -f  arch/x86/include/../coco/sev/internal.h 
/mnt/kernel/kernel/linux/arch/x86/coco/sev/internal.h

And /mnt/kernel is my kernel-sources-containing SSD :-)

In any case, good catch!

I'll do the "../../" so that it is perfectly clear and future
potential include directives changes do not break this.

Thx.
