Thanks for all the clean-up.
I have applied your patches and tested on ia64 (8 nodes).
patch1: (but not the hunks that Kornilios had supplied)
patch2: bitmask memory leaks numa_tonode_memory()
numa_get_interleave_mask_v1() numa_run_on_node_mask_v2()
patch3: leaks in numa_get_membind_v1() numa_get_run_node_mask_v1()
numa_get_run_node_mask_v1() numa_get_run_node_mask_v2 numa_run_on_node()
patch4: return freeable bitmasks
patch5: parsing of /proc/self (extends Brice's)
patch6: numademo memtest page allocation overhead
patch8: test/checkaffinity script
I did not apply patch 7. I think you and Andi agreed on that.
