Nadav Amit ae052e3ae0 x86/kprobes: Fix 1 byte conditional jump target ... Commit 3bc753c06d ("kbuild: treat char as always unsigned") broke kprobes. Setting a probe-point on 1 byte conditional jump can cause the kernel to crash when the (signed) relative jump offset gets treated as unsigned. Fix by replacing the unsigned 'immediate.bytes' (plus a cast) with the signed 'immediate.value' when assigning to the relative jump offset.
