UML/x86_64

UML has been ported to x86_64. The patch for 2.6.4 is available at

	http://www.user-mode-linux.org/mirror/uml-patch-x86-64-2.6.4.bz2

Note that this is separate from the 2.6.4 UML patch, and must be applied to a 2.6.4 + uml-patch-2.6.4 tree. It will remain separate until I get it all merged cleanly into my tree. At that point, the separate x86_64 patch will disappear.

This patch is fairly nasty in places, and the build is also fairly unclean, so avert your eyes if you are squeamish. This will get better as I merge it into my pool.

The nastiness aside, it does build and you do get a robust UML.

My thanks go to PathScale (pathscale.com) for sponsoring this work and providing access to hardware to make it possible.

Finally, as I do the merge (and afterwards), I need access to an Opteron to make sure I don't break this port. So, if anyone has such a box that I can have access to, let me know.

Hi Jeff,

thanks for your work! I just tried the patch on my AMD64 machine. "make linux ARCH=um" fails with

CC arch/um/kernel/ksyms.o
arch/um/kernel/ksyms.c:91: error: `dump_thread' undeclared here (not in a function)
arch/um/kernel/ksyms.c:91: error: initializer element is not constant arch/um/kernel/ksyms.c:91: error: (near initialization for `__ksymtab_dump_thread.value')
arch/um/kernel/ksyms.c:91: error: __ksymtab_dump_thread causes a section type conflict
make[1]: *** [arch/um/kernel/ksyms.o] Error 1

When commenting out that line in arch/um/kernel/ksyms.c and disabling module support in the kernel configuration, it works! So, just a little correction to your patch. Now I'll try and see if it works ;)

Greetings,
Martin
