[...]  This series also includes a change which prohibits probing 
on the address in .entry.text because the code is used for very 
low-level sensitive interrupt/syscall entries. Probing such code 
may cause unexpected result (actually most of that area is already 
in the kprobe blacklist).  So I've decide to prohibit probing all 
of them. [...]
Does this new blacklist cover enough that the kernel now survives a 
broadly wildcarded perf-probe, e.g. over e.g. all of its kallsyms?
That's generally the purpose of the annotations - if it doesn't then 
that's a bug.

Thanks,
