From: Andi Kleen <ak@linux.intel.com>
Kernels don't like any reordering of initcalls between files, as several
initcalls depend on each other. LTO is allowed to reorder as it wishes
and previously needed to use -fno-toplevel-reordering to prevent boot
failures. Now we can use __noreorder per symbol. So mark initcall
functions as such.
