OpenRISC: System calls
The OpenRISC Linux kernel conforms to the "generic" syscall interface which contains only the reduced set of syscalls deemed necessary for new architectures. Unfortunately, the uClibc port for OpenRISC does not fully support this reduced set; as such, an additional patch available out-of-tree needs to be applied to the kernel in order to use the current uClibc. This is just a temporary measure until the libc port can be straightened out; it is likely that OpenRISC will make the transition to glibc shortly where the generic syscall interface is better supported.
