Finally I managed to do the git bisect with your indications. The result:
# git bisect bad
026cee0086fe1df4cf74691cf273062cc769617d is the first bad commit
commit 026cee0086fe1df4cf74691cf273062cc769617d

params: <level>_initcall-like kernel parameters
This patch adds a set of macros that can be used to declare
kernel parameters to be parsed _before_ initcalls at a chosen
level are executed. We rename the now-unused "flags" field of
struct kernel_param as the level. It's signed, for when we
use this for early params as well, in future.
Linker macro collating init calls had to be modified in order
to add additional symbols between levels that are later used
by the init code to split the calls into blocks.
