Ensure that kernel_init_freeable() is not inlined into non __init code
Commit d6b2123802d "make sure that we always have a return path from kernel_execve()" reshuffled kernel_init()/init_post() to ensure that kernel_execve() has a caller to return to. It removed __init annotation for kernel_init() and introduced/calls a new routine kernel_init_freeable(). Latter however is inlined by any reasonable compiler (ARC gcc 4.4 in this case), causing slight code bloat. This patch forces kernel_init_freeable() as noinline reducing the .text bloat-o-meter vmlinux vmlinux_new add/remove: 1/0 grow/shrink: 0/1 up/down: 374/-334 (40) function old new delta kernel_init_freeable - 374 +374 (.init.text) kernel_init 628 294 -334 (.text) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
