Hi Joerg & *,

I redid my testing on bare metal and in a VM (as with my previous
efforts:, same setups
and coverage,
plus CONFIG_X86_DEBUG_ENTRY_CR3 enabled too) with the
pti-x32-v7 branch,
and I didn't encounter any issues. The two DRM
drivers that were
triggering bugs in some of the prior iterations
are both behaving
properly for me.
