From c5f2420a063fcc5a4cd6610c3ef6934827853001 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Mon, 2 Oct 2006 02:18:46 -0700 Subject: [PATCH] AVR32: Implement kernel_execve Move execve() into arch/avr32/kernel/sys_avr32.c, rename it to kernel_execve() and return the syscall return value directly without setting errno. This also gets rid of the __KERNEL_SYSCALLS__ stuff from unistd.h and expands #ifdef __KERNEL__ to cover everything in unistd.h except the __NR_foo definitions.
