x86 idle floppy: deprecate disable_hlt()
Plan to remove floppy_disable_hlt in 2012, an ancient workaround with comments that it should be removed. This allows us to remove clutter and a run-time branch from the idle code. WARN_ONCE() on invocation until it is removed. cc: x86@kernel.org cc: stable@kernel.org # .39.x Signed-off-by: Len Brown <len.brown@intel.com>
