[RFC v3 4/9] kdb: Rename kdb_register_repeat() to kdb_register_flags()

25 Apr 2014

From: Anton Vorontsov anton.vorontsov@linaro.org
We're about to add more options for commands behaviour, so let's give
a more generic name to the low-level kdb command registration function.
There are just various renames, no functional changes.
