Hi Christian, Janosch, Heiko,
Here is a new version for the AR/MEM_OP issue I'm attempting to address.
(Thank you, Heiko, for the offline chat!)
Changes:

[HC] Drop the AR swap in MEM_OP path
[HC] Remove WARN and don't do save_access_regs on !bool
v2: https://lore.kernel.org/r/[email protected]/
[HC] Add a flag to indicate access registers have been loaded
v1: https://lore.kernel.org/r/[email protected]/
[CB] Store access registers around memop ioctl
[JF] Add a kernel selftest
