Patch series "Fix some GDB command error and add some GDB commands", v3.

Fix some GDB command errors and add some useful GDB commands.


This patch (of 5):

Commit 7988e5ae2be7 ("tick: Split nohz and highres features from
nohz_mode") and commit 7988e5ae2be7 ("tick: Split nohz and highres
features from nohz_mode") move 'tick_stopped' and 'nohz_mode' to flags
field which will break the gdb lx-mounts command:

(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named nohz_mode.
Error occurred in Python: There is no member named nohz_mode.

(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named tick_stopped.
Error occurred in Python: There is no member named tick_stopped.

We move 'tick_stopped' and 'nohz_mode' to flags field instead.
