Oh, Andi, it isn't a short time work. especially we use asm-generic/unistd.h instead of score old asm/unistd.h. You see, the most work was focus on glibc/applications. linux-arch-owner@vger.kernel.org д?? 2009-06-23 18:51:47: > Before we commit the code to linux.org, > Linux had run on spct6600 score platform well. > It had passed LTP test and could run many general applications. > S+core application depend on glibc-2.3.6, which support static > and dynamic applications. void merge_score_to_upstream(void) { if (asm-generic is the right direction for all linux arch) { if (merge score code) { It's easy for us to update score code and commit the asm-generic problems we meet. } else { People will pay no attation to score/asm-generic problems. printk("it haven't help asm-generic to stable."); } else { we could use score old asm/unistd.h instead. } } I think merge score to upstream will be no harm to linux kernel.

As a new comer, we don't know what we should or shouldn't do, Since we begin to commit linux/score code to linux.org, we found the best way is as simple as possible, because in linux world people also have the different suggestions, it will make us confused and don't know what todo next soon. The simple code has little error. We think it isn't the right time to add utrace code so we don't do it.
