I have looked through it and spotted nothing obviously wrong, but I can't
afford any further testing, especially at run time, sorry.
One point to note -- it seems to me the code currently assumes a 32-bit
model, i.e. the use of the -msym32 GCC option suitable for a 64-bit kernel
loaded to a CKSEG0 address (cf. KBUILD_SYM32 in arch/mips/Makefile), tools
support permitting. That means it does not (correctly) support kernels
loaded to an XPHYS address as required for some platforms (or otherwise
chosen for testing such a configuration; modulo some processor errata and
bootloader limitations, it is generally OK to run the kernel from XPHYS on
64-bit chips even if the entire RAM fits into CKSEG0).
For the avoidance of doubt -- I'm just mentioning it to emphasise a
possible future direction for improvement of this code -- not an objection
against this submission, that is certainly a good foundation for future
Thanks to everybody involved.
