GPL syscall note
Note that, as in the Linux syscall note for the GPL, the seL4 kernel GPL license does not cover user-level code that uses kernel services by normal system calls - this is merely considered normal use of the kernel, and does not fall under the heading of "derived work". Syscall headers are provided under BSD.
