Addition of move_pages() syscall tests. The updated patch fixes the warning messages and removes the print_bitmask function (it's not used) which causes build errors on powerpc. Signed-off-by: Vijay Kumar B. <vijaykumar@bravegnu.org>.

+/*
+ * NAME
+ * move_pages11.c
+ *
+ * DESCRIPTION
+ * Failure when trying move shared pages.
+ *
+ * ALGORITHM
+ * 1. Allocate a shared memory in NUMA node A.
+ * 2. Fork another process.
+ * 3. Use move_pages() to move the pages to NUMA node B, with the
+ * MPOL_MF_MOVE_ALL.
+ * 4. Check if errno is set to EPERM.
+ *
+ * USAGE: <for command-line>
+ * move_pages11 [-c n] [-i n] [-I x] [-P x] [-t]
+ * where, -c n : Run n copies concurrently.
+ * -i n : Execute test n times.
+ * -I x : Execute test for x seconds.
+ * -P x : Pause for x seconds between iterations.
+ * -t : Turn on syscall timing.
+ *
+ * History
+ * 05/2008 Vijay Kumar
+ * Initial Version.
+ *
+ * Restrictions
+ * None
