[seL4] why do there are some differences between camkes branch and master branch in lib seL4/libsel4muslcsys

Hi, Siwei Zhuang, Why do there are some differences between camkes branch and master branch in lib seL4/libsel4muslcsys? The lib seL4/libsel4muslcsys is the foundation of libmuslc, it shoud be a libc for any seL4 program, and there should be no diference among any branches. https://github.com/seL4/libsel4muslcsys/commits/camkes Xilong Pei Tongji University 2015/5/29
