Masami Hiramatsu (Google) 1cbf3882cb x86/kprobes: Update kcb status flag after singlestepping 
commit dec8784c9088b131a1523f582c2194cfc8107dc0 upstream.

Fix kprobes to update kcb (kprobes control block) status flag to
KPROBE_HIT_SSDONE even if the kp->post_handler is not set.

This bug may cause a kernel panic if another INT3 user runs right
after kprobes because kprobe_int3_handler() misunderstands the
INT3 is kprobe's single stepping INT3.

Fixes: 6256e668b7 ("x86/kprobes: Use int3 instead of debug trap for single-step")
