Rajalakshmi Srinivasaraghavan b42f8cad52 powerpc: strstr optimization ...

This patch optimizes strstr function for power >= 7 systems.  Performance
gain is obtained using aligned memory access and usage of cmpb
instruction for quicker comparison.  The average improvement of this
optimization is ~40%.  Tested on ppc64 and ppc64le.
