Sadly I've only now noticed that this hasn't been done the way it

Protection keys define a new 4-bit protection key field(PKEY) in bits 62:59 of
leaf entries of the page tables.
PKRU register defines 32 bits, there are 16 domains and 2 attribute bits per
domain in pkru, for each i (0 ≤ i ≤ 15), PKRU[2i] is the access-disable bit for
protection key i (ADi);
