I have no idea - all that I can say about the problem is that the uncompressor
does not think that the gzip'ed kernel image is valid for one reason or another.
Someone with this problem will have to investigate why this is.  As far as I am
concerned (my concern is the kernel at the moment), the problem is not the
kernel, nor the kernel source.

No!  That's not the way it works.  The kernel has been designed to allow all
these architectures to exist without resorting to #ifdefs.  GCC/EGCS has the
idea of inline functions - these are used heavily by the kernel.  There is
actually a lot of inlined code in the include files, both in include/asm-*
and include/linux.

For instance, the page table manipulation as far as the 'normal' kernel code
is concerned is a three-level affair.  However, defining the correct constants
and inline functions you can collapse this down to a single level if you so wish
without modifing or replacing the existing code.

Again, what is the error?

If you want to recompile my sources for x86, all you have to do is to:
1. make clean
2. change the ARCH := line in the top level make file and CROSS_COMPILE
3. make config
4. make dep
5. make clean
6. make zImage or make bzImage


PS, your mailer appears to be getting CC: lines to multiple people wrong.
This is what I'm seeing:

CC: [EMAIL PROTECTED]@vger.rutgers.edu

Since this is invalid (containing a '.' between the addresses), I have to
manually copy the CC: line each time, which makes it extremely annoying to
reply to.
