[Intel-xe] [PATCH v2 0/2] Update Xe uAPI in a minimally invasive way

[Christopher Snowhill]

This series takes off from mlankhorst's attempt to do the same, except
instead, it tries to be as minimally invasive to the original uAPI as
possible, by only inserting padding where appropriate to ensure all
32-bit members are 32-bit aligned, and all 64-bit members are 64-bit
aligned. This should have zero effect on 64-bit hosts versus 64-bit
userspace, so existing native software will operate the same with or
without the update. The only real change is 32-bit compat support for
multilib userspace, which was previously broken.

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

v2:
  Removed extensions checks where there were none originally. (José)
  Moved extraneous parentheses to the correct places. (Lucas)
