Hi,
The basic question is, has the GPR r11 a dedicated function (to point to the previous stack frame)
or is it still a volatile GPR, according to EABI definition ?
In the case of a dedicated function was assigned, the trampoline code generation in
arch/powerpc/kernel/module_32.c
must be corrected. I'd suggest to use r12 instead of r11, in this case.
Best Regards
Steffen
