Hi,
Here are 2 bugfixes I have found in set_resume_flags().
The [1/2] fixes a bug which I have introduced by commit abd82e533d88 ("x86/kprobes: Do not decode opcode in resume_execution()"), and [2/2] has been there in the origin of the x86 kprobes (before 2.6.12). Anyway, [2/2] is something like a cosmetic patch, because the original code was mis- understanding the opcode encoding, but the result is same.
Thank you,
