2014-02-15 Thread Stefani Seibold
This patch add the functions vdso_gettimeofday(), vdso_clock_gettime() and vdso_time() to the 32 bit VDSO. The reason to do this was to get a fast reliable time stamp. Many developers uses TSC to get a fast time stamp, without knowing the pitfalls. VDSO time functions a fast and a reliable way, be
