This patch adds the following operations: - SYS_OPEN - SYS_CLOSE - SYS_WRITE - SYS_READ - SYS_ERRNO - SYS_REMOVE - SYS_SEEK The use of utility functions mem_read() and mem_write() add an unnecessary memcpy() call. All buffer transfer could be done directly in the sl->q_buf data instead of using a temporary transfer buffer. However, given the relative slowness of target memory transfer, I don't think that this has a big impact on performances
