The original patch isn't yours, but, what?  Apply this patch, run 'make
am335x_evm_defconfig savedefconfig', copy 'defconfig' back over to
configs/am335x_evm_defconfig and see what actually changed vs top of
tree.  We really want to know what you're now turning off compared with
the regular config and perhaps look into why that's now overflowing, and
with what compiler?  That's some rather large growth.  Thanks!
