// TODO(markus): This is an incredibly dirty hack to make the syscallTable
// live in r/o memory.
// Unfortunately, gcc doesn't give us a clean option to do
// this. Ultimately, we should probably write some code that
// parses /usr/include/asm/unistd*.h and generates a *.S file.
// But we then need to figure out how to integrate this code
// with our build system.
