RFR(XS) 8181055: "mbind: Invalid argument" still seen after 8175813

[Zhengyu Gu]

Hi,

There is a corner case that still failed after JDK-8175813.

The system shows that it has multiple NUMA nodes, but only one is 
configured. Under this scenario, numa_interleave_memory() call will 
result "mbind: Invalid argument" message.

Bug: https://bugs.openjdk.java.net/browse/JDK-8181055
Webrev: http://cr.openjdk.java.net/~zgu/8181055/webrev.00/


The system NUMA configuration:

Architecture: ppc64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Big Endian
CPU(s): 8
On-line CPU(s) list: 0-7
Thread(s) per core: 4
Core(s) per socket: 1
Socket(s): 2
NUMA node(s): 2
Model: 2.1 (pvr 003f 0201)
Model name: POWER7 (architected), altivec supported
L1d cache: 32K
L1i cache: 32K
NUMA node0 CPU(s): 0-7

Thanks,
