V0.7.44-02 does not even compile for me.  It appears to be full of merge
errors.

I get these errors with "make oldconfig":

  HOSTLD  scripts/kconfig/conf

Then, looks like mcount-wrapper.S is two copies of the same file.  To
have any chance of building this patch was required:

And it still bombs out here.  This is where I gave up:
