x86, 64-bit: ifdef out struct thread_struct::ip
struct thread_struct::ip isn't used on x86_64, struct pt_regs::ip is used instead. kgdb should be reading 0 always, but I can't check it. [ Impact: (potentially) reduce thread_struct size on 64-bit ] Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Cc: containers@lists.linux-foundation.org LKML-Reference: <20090503233015.GJ16631@x200.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>
