Hello, There is a piece of code in the early initialization of the 2.6 kernel that identifies the cpu type and then tries to eliminate code that does not apply to the current cpu. This is done by writing nop's over sections of code that are not needed (do_cpu_ftr_fixups in arch/ppc/kernel/misc.S) When I try to run the kernel in a ppc emulator, I get a segmentation fault in do_cpu_ftr_fixups. From examining the section headers of the vmlinux, the text section is marked as readonly. The piece of code above mentioned is trying to write a nop to memory location inside the text section. Since the kernel does run on boards with ppc cpu's, can somebody explain how come this is actually working ? Or if/where I am mistaking with my assumptions ?
