Yes, I did realise it. The unintended movement of
flush_ptrace_hw_breakpoint() from flush_thread() is a result of a
patching error (while forward porting).

A fix for this issue along with those pointed out by BenH will be a part
of the next version of the patch, that I intend to send very soon.

Thanks for reviewing them.
