Would this break the some of the assumptions that uvm_loan makes?

Is it worth to enable page loaning on virtual address indexed
cache (and physical address tagged) systems?

Page loaning implies read-only pages, so what issues are there with incompatible cache aliases?



Current page loaning code doesn't consider about virtual cache
indexes on new P-V mappings (unless yamt-kmem branch is complete?)
and it creates a bunch of possible aliases which might be
much more pain than copying pages.
