[Intel-xe] [RFC PATCH 0/2] Draft: Update Xe uAPI for 32-bit compat, invasively

[Christopher Snowhill]

This attempt brings in Maarten Lankhorst's original uAPI update, with
suggested changes made to make up the difference. As long as we're
attempting to bring up 32-bit compat capability, we may as well go
whole hog and just break things. Better that way than to deal with the
mess later.

Also introduces field validation against all of the padding and
reserved fields, which must be zero, in a separate commit.

This is the invasive update, as a draft, for comment and examination.
It's probably not going to be applied any time soon, but it's here,
and it's been updated based on the comments against the original
invasive attempt.

v3:
  Redid everything, maybe this one will be a little more permanent.
v2:
  Removed extensions checks where there were none originally. (José)
  Moved extraneous parentheses to the correct places. (Lucas)
