There was no resistance ever.  There were just the normal review
comments.

If there are no further complaints that usually menas the stuff is
sitting in the queue waiting to be processed.  Sorry, but my bandwidth
_is_ limited.

The problem with this new approach is that Linux kernel images are NOT
freely relocatable.  They do have a fix entry point, even if this is
not an absolute address, but a relative one.  The natural way to
handle this is exactly that:  add support for images with relative
)offset based) load and entry point addresses.

Your new approahc is indeed simpler - actually it is too simplistic,
as you cannot record load address / entry point information any more.
It may work when using the kernel wrapper - but what if you don't want
to do that?

The NAK remains.  The new code will not go in.
