Previously, the vmstat (virtual memory statistics) tool incorrectly reported the disk I/O as swap-in on ppc64 and other architectures that do not support the TRANSPARENT_HUGEPAGE configuration option in the kernel. With this update, the vmstat tool no longer reports incorrect statistics and works as expected.
