I am surprised that syscalls have been removed. Anyway, I plan to write a device node with read and write functions just so that I can call a method from a user space. What are my other choices? -- Gautam

Well, most syscall() versions get 6 argument calls wrong (not sure if that is finally fixed). _syscall*() didn't support -fPIC for larger argument counts (_syscall0-2 never had a problem) So all alternatives short of writing your own stub had various issues. If you needed 6 argument calls _syscall* was typically the best alternative. -Andi
