[PATCH 2/6] rename the provided execve functions to kernel_execve
From: Arnd Bergmann
Date: Wed Aug 30 2006 - 08:52:53 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.

- * we need this inline - forking from kernel space will result
- * in NO COPY ON WRITE (!!!), until an execve is executed. This
- * is no problem, but for the stack. This is handled by not letting
- * main() use the stack at all after fork(). Thus, no function
- * calls - which means inline code for fork too, as otherwise we
- * would use the stack upon exit from 'fork()'.
- *
- * Actually only pause and fork are needed inline, so that there
- * won't be any messing with the stack from main(), but we define
- * some others too.
