[PATCH 09/13] pseries: Fix endian issues in onlining cpu threads

[tim.gardner at canonical.com]

From: Thomas Falcon <tlfalcon at linux.vnet.ibm.com>

BugLink: http://bugs.launchpad.net/bugs/1391953

The ibm,ppc-interrupt-server#s property is in big endian format.
These values need to be converted when used by little endian
architectures.
