[PATCH] rename the provided execve functions to kernel_execve
Some architectures provide an execve function that does not set errno, but instead returns the result code directly. Rename these to kernel_execve to get the right semantics there. Moreover, there is no reasone for any of these architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so remove these right away.
