It'd be interesting, if it doesn't take you too much time. I'd have wanted to rather make this a conditional like #if defined(CONFIG_XEN) && defined(CONFIG_X86) as I expect this to be rare. >If the code is clearly x86-specific >(e.g. in arch/i386 or include/asm-x86), I agree the >_X86_ part is superfluous. Sure. But I'd like this to be consistent, which is why, for now, I used CONFIG_X86_XEN everywhere.
