Yes, probably not a vanilla kernel material, but could be very well used
for testing to further isolate whether it is kernel or userspace
corrupting the memory mapped eeprom.
Absolutely.
Would it help and would it be feasible to drastically shorten the
lifetime of the MMIO mapping? I.e. only have it mapped briefly during
the driver probe, and temporarily whenever a userspace tool like ethtool
needs it.
