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; } - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
