The current api from safe_syscall_base() is to return -errno, which is the interface provided by *some* linux kernel abis. The wrapper macro, safe_syscall(), detects error, stores into errno, and returns -1, to match the api of the system syscall(). For those kernel abis that do not return -errno natively, this leads to double syscall error detection. E.g. Linux ppc64, which sets the SO flag for error. Simplify the usage from C by moving the error detection into assembly, and usage from assembly by providing a C helper with which to set errno.
