This doesn't change the "debug-only"-ness of the option. Observe in the first hunk to hvm.h that opt_hvm_fep is defined to 0 in a non-debug build, which causes this hunk to be omitted. This actually matches the original introduction of opt_hvm_fep, before it was reduced in scope to only hvm.c. I now need it available again in other translation units. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
