Hi Steve,

Here is the 3rd version of the patches to update the bootconfig.
I added 3 patches to fix some issues. One issue is from Julio which
fixes a compilation error ([5/6]*). And the other 2 are fixing
ftrace2bconf script ([4/6]) and cleanup test script ([6/6]).

* https://lore.kernel.org/all/20210831033256.5973-1-jcfaracco@gmail.com/T/#u

The 1st one is for bootconfig memory cleanup when exiting init stage.
The 2nd one and 3rd one are for reordering the init parameters from
bootconfig.
Since the current kernel concatenate the kernel cmdline and the
bootconfig parameters as below.

[bootconfig kernel params][cmdline] -- [init cmdline][bootconfig init params]

This is bit odd because for the kernel parameters, user passed cmdline
can override the previous (bootconfig) one, but for the init cmdline,
bootconfig may override the parameter.
Thus, this series invert the order as the following.

[bootconfig kernel params][cmdline] -- [bootconfig init params][init cmdline]

The 3rd patch is adding how to use the bootconfig for passing kernel
and init parameters.

Thank you,
