From ae903caae267154de7cf8576b130ff474630596b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 14 Dec 2012 12:44:11 -0500 Subject: Bury the conditionals from kernel_thread/kernel_execve series All architectures have CONFIG_GENERIC_KERNEL_THREAD CONFIG_GENERIC_KERNEL_EXECVE __ARCH_WANT_SYS_EXECVE None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers of kernel_execve() (which is a trivial wrapper for do_execve() now) left. Kill the conditionals and make both callers use do_execve().
