[Xen-devel] [PATCH] libxc x86-64 enablement

[Jerone Young <jyoung5@xxxxxxxxxx>]

Here is some of the preliminary work for libxc to work and compile
properly under x86-64 .

libxc_x64_makefile_patch[1].diff:
First, I've set files such as xc_ptrace,xc_plan9_build,xc_vmx_build, &
xc_linux_build to build only for x86_32. As we enable these to work will
add we should add them back. Now everyone may not agree with my changes,
but this can be resolved through discussion. I do wonder what tools ia64
guys are using...because it can't be these...can it ?

libxc_x64_xc_private_patch[2].diff:
Adds need definitions for x86-64.

libxc_x64_xc_linux_build_x64_patch[3].diff:
I've added a new file xc_linux_build_x64.c. I did this with the future
in mind of supporting both 32bit and 64bit domains. Currently we will
only support 64bit domains. So this file will have the xc_linux_build
function for x86-64. Once 32bit domain support is added then we will
rename the function to xc_linux_build_x64 or something else that
distinguishes it as our x86-64 build linux function, and xc_linux_build
would be our 32bit build function (located in xc_linux_build.c). 

Don't know if anything works yet, but once all the code is in place and
working I'll be able to kick out any bugs. I also don't know if I am
zeroing out the 4 level page table correctly. So as you can see from the
comments..I'm not sure about that work.
