https://jira.sw.ru/browse/PSBM-66876
If one tries to place a kprobe on an instruction that uses %rip-relative addressing, register_kprobe() fails with -EINVAL because __copy_instruction() from arch/x86/kernel/kprobes/core.c incorrectly returns 0. This makes it harder to use kprobes for the kernel debugging and might affect the tools like SystemTap as well. Here is an old patch of mine (mainlined) that fixes the issue.
