[PATCH 2/7] rename the provided execve functions to kernel_execve
From: Arnd Bergmann
Date: Sun Aug 27 2006 - 19:56:50 EST
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.
