I tried to do a 'git format-patch' on other projects, but when I pull my
patch from the master project, my history starts to look very bizarre.
I just did a 'git diff' and attached that to my mail.  Is a 'git
format-patch' the right way to do this?

I need the '-mabi=aapcs-linux' as per the thumb target.  Otherwise, it
is using 'apcs-gnu'.  It keeps dying in _start, without this option.  Is
this dependant on the kernel config (OABI,EABI)?  I compile without OABI
support at all.  Is there any klibc 'structure' (perl, etc) to parse the
'.config' in the linux build directory?

Regards,
Bill Pringlemeir.
