Linux kernel helpers support is provided to android for its TLS implementation. This fix addresses this by modifying
the TLS access functions to use the kernel helper.
This Fix is verified on ST Ericsson's U8500 platform and Submitted on behalf of a third-party:
Surinder-pal SINGH from STMicroelectronics.
