Hmm, maybe we should have an asm-generic/unistd.h then
containing something like

#ifndef __KERNEL__
#include <sys/syscall.h>
#define _syscall0(type,name) \
type name(type1 arg1) \
{ \
	return syscall(__NR_ ## name); \
}
#define _syscall1(type,name,type1,arg1) \
type name(type1 arg1) \
{ \
	return syscall(__NR_ ## name, arg1); \
}
#define _syscall1(type,name,type1,arg1,type2,arg2) \
type name(type1 arg1, type2 arg2) \
{ \
	return syscall(__NR_ ## name, arg1, arg2); \
}
// ...
#endif
