Christophe Leroy ee7c3ec3b4 powerpc/ebpf32: Use standard function call for functions within 32M distance ... If the target of a function call is within 32 Mbytes distance, use a standard function call with 'bl' instead of the 'lis/ori/mtlr/blrl' sequence. In the first pass, no memory has been allocated yet and the code position is not known yet (image pointer is NULL). This pass is there to calculate the amount of memory to allocate for the EBPF code, so assume the 4 instructions sequence is required, so that enough memory is allocated.
