hm, why not have a single test for !highest_pfn:
if (!highest_pfn) {
if (!kvm_para_available()) {
printk(KERN_WARNING
"WARNING: strange, CPU MTRRs all blank?\n");
WARN_ON(1);
}
return 0;
}
? But yeah, your patch looks good otherwise.
I'm not sure how we could detect pure Qemu instances - perhaps it should
define some special MSR or something?
