Subject[RFC/PATCH 2/3] init: Initialize jump_labels before early parameters
Date
We want to use jump_labels in the debug_objects code so that when
debug_objects aren't enabled by default we can skip debug_object
code. Move the jump_label initialization before the early
parameter parsing so that debug_objects code can enable and
disable itself according to kernel command line parameters.

This also opens the window to using static keys for pr_debug().
I tried and wound up in circular dependency hell.
