Tried the following code on rc1 and rc2 and it worked fine on ia64:
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
#include <numaif.h>
int main(int argc, void *argv[])
{
char *p;
unsigned long nodes = 0x01;
p = mmap(0, 32768, PROT_READ| PROT_WRITE, MAP_PRIVATE| MAP_ANONYMOUS, 0, 0);
mbind(p, 32768, MPOL_BIND, &nodes, 64, 0);
p[34] = 89;
return 0;
}
