Hey Thomas, I'd like to move ahead with my patchset and make some forward progress in LKML submission. If you've got something brewing regarding the FPU context on x86 and ARM, I'm happy to wait a bit longer so as to build on that. But if that is instead a far-off theoretical eventual thing, perhaps it's better for me to move ahead as planned, and we can switch to the superior FPU semantics whenever you get around to it? Either way, please let me know what you have in mind so our plans can stay somewhat sync'd. Talk soon, Jason
