Hi,
Sorry to butt in as an outsider, but this seems like a shockingly disrespectful
discussion for such a wide CC list.
I don't want to make rules how you discuss things (I very rarely contribute),

Sometimes you might want to use MAP_POPULATE to ask a device driver to
initialize the device memory in some specific manner. SGX driver can use
this to request more memory by issuing ENCLS[EAUG] x86 opcode for each
page in the address range.
