Yes.
I can confirm I checked x86 patch by patch with CONFIG_IOREQ_SERVER, as
for !CONFIG_IOREQ_SERVER I can't recollect to be 100% sure, but likely I
tested also patch by patch.
Anyway, I have just rechecked.
Probably it is because this header isn't in use with
!CONFIG_IOREQ_SERVER since all users are x86/hvm/* and common/ioreq.c
