Greer" Commit 923df96b9f31b7d08d8438ff9677326d9537accf (ARM: 7451/1: arch timer: implement read_current_timer and get_cycles) modifies get_cycles() such that it calls read_current_timer(). Unfortunately, the 'read_current_timer' symbol is not exported so when a driver that calls get_cycles() is built as a module, an undefined reference error occurs. A good example is the crypto/tcrypt.c (CONFIG_CRYPTO_TEST) driver because it calls get_cycles() and can only be built as a module. Fix this error by exporting the 'read_current_timer' symbol.
