commit 8e127846fc97778a5e5c99bca1ce0bbc5ec9 upstream.
The ptrace PEEKUSR/POKEUSR (aka PEEKUSER/POKEUSER) API allows a process

To get/set a register, the API takes an index into an imaginary address
space called the "USER area", where the registers

We deprecated open coding of the transfer queue back in 2017 so it's high
time we finished up converting drivers to use the standard message queue
code. The mpc52xx-psc driver is fairly straightforward so convert to use
transfer_one_message(), it looks like the driver would be a good fit for
