elfcore.h : Fix UML build breakage
Commit a65e7bfcd74e4c0939f235d2bf9f48ddb3a57991 broke the UML build with the following error - In file included from fs/proc/kcore.c:17: include/linux/elfcore.h: In function 'elf_core_copy_task_regs': include/linux/elfcore.h:129: error: implicit declaration of function 'task_pt_regs' Fix this by restoring the previous behavior of returning 0 for all arches like UML that don't define task_pt_regs.
