Long" The pt_regs_offset structure is used for HAVE_REGS_AND_STACK_ACCESS_API feature and has identical definitions in four different arch ptrace.h include files. It seems unlikely that definition would ever need to be changed regardless of architecture so lets move it into include/linux/ptrace.h. Signed-off-by: David A.
