Any chance we could just retire the legacy FS/DS names that are
horribly misleading these days?  E.g. turn the whole thing into:

	uaccess_kernel_enable();

	...

	uaccess_kernel_disable();

which for now turn into the existing calls with a nesting counter
in task_struct, with the hopes of cleaning all that mess up
eventually.
