nuttx/syscall/syscall_lookup.h
Gregory Nutt 3c30cf1f05 Squashed commit of the following: 
task_spawn() and posix_spawn() are NuttX OS interfaces.  In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call.  Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters.  Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
     *

In order to support builtin in function in protected mode, a task_spawn() system call must be supported.  Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters.  This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures.  Better to get more creative.
