- Replace f_dentry with f_path.dentry (f_dentry definition was
removed);
- Replace instruction_pointer() definition with regs->pc for ARM64
(it is casted to unsinged long, so, is treated as simple number);
- Replace hlist_add_after() by version-dependent definition
(now it is hlist_add_behind() in kernel);
- Replace dereference of task->real_start_time with definition
(on recent kernels its type was changed);
- Redefined __get_cpu_var() for modern kernels
(it was removed from kernel);
- Make kernel version-dependent .map/.unmap methods for
pipe_buf_operations;
- Add necessary include for using splice.h;
- Replace strict_strtoul() with kstrtoul() (strict_strtoul()
