There is code in the linker (for 64 bit only: bfd/elf64-ppc.c) to automatically generate them whenever they are needed. I suspect you compile with -Os. But I don't think you can use these functions when doing a sibling call since restgpr0_nn implies a return to the caller. restgpr1_nn would be different... And those are generated calls so I don't see how we can fix them. I started building with gcc 4.6.3/binutils 2.22 today. gcc 4.6.0/binutils 2.21 do not produce this error, it produces this instead (which has been happening for a long time): powerpc64-linux-ld: TOC section size exceeds 64k So presumably there's some new error checking that we're hitting, I imagine it was always broken, but now it's being more explicit. I'm not so sure. I suspect gcc, but upgrading gcc and binutils at the same time may not be the wisest...

According to the PowerPC EABI specification, the GPR r11 is assigned the dedicated function to point to the previous stack frame. In the powerpc-specific kernel module loader, do_plt_call() (in arch/powerpc/kernel/module_32.c), the GPR r11 is also used to generate trampoline code. This combination crashes the kernel, in the following case: + The compiler has been generated the prologue and epilogue, which is part of the .text section. + The compiler has been generated the code for the module init entry point, part of the .init.text section (in the case it is marked with __init). + By returning from the module init entry point, the epilogue is called by doing a branch instruction. + If the epilogue is too far away, a relative branch instruction cannot be applied. Instead trampoline code is generated in do_plt_call(), in order to jump via register. Unfortunately the code generated by do_plt_call() destroys the content of GPR r11. + Because GPR r11 does not more keep the right stack frame pointer, the kernel crashes right after the epilogue. The fix just uses GPR r12 instead of GPR r11 for generating the trampoline code. According to the statements from Freescale, this is also save from EABI perspective. I've tested the fix for kernel 2.6.33 on MPC8541.
