Section mismatch warnings for early memory allocations

Checking for section mismatches across all of vmlinux is kicking
out a bunch of new warnings. Many of them real, but I have a
few from routines like this:

foo(...)
{
static int first_time = 1;

if (first_time) {
all_i_need = alloc_bootmem(NR_CPUS * xxx);
first_time = 0;
}
... use smp_processor_id() to use pre-allocated memory ...
}


Now this is safe, since the first call to foo is made when alloc_bootmem
is still available. But it kicks out a "Section mismatch" warning since
a non __init routine (foo) is calling an __init one.

Any suggestions on how to tell modpost that this is safe?
