2.4 is a no go for all architectures with gcc >= 4.0.0 and in case of MIPS
even gcc 3.4 is somewhat dubious.

It's probably a matter of configuration then. Basically with our current
uaccess.h and gcc >= 4.0.1 the attempt to pass a pointer to a const
variable as the pointer argument to get_user or __get_user will blow up.
It's always been a bug - but gcc before 4.0.1 were accepting this
silently.
