__NR_exit is nowhere used. On most architectures it was removed by commit 135ab6ec8fda ("[PATCH] remove remaining errno and __KERNEL_SYSCALLS__ references") but not on powerpc.
powerpc removed __KERNEL_SYSCALLS__ in commit 3db03b4afb3e ("[PATCH] rename the provided execve functions to kernel_execve"), but __NR_exit was left over.
