[PATCH] 1/2 daemonize() calls reparent_to_init() cleanup

[Rusty Russell <rusty@rustcorp.com.au>]

Initialize child_reaper at idle thread entry: eg. ksoftirqd's PPID is
0, because it calls reparent_to_init() before child_reaper is
initialized.

Name: Early child_reaper initialization
Author: Rusty Russell
Status: Trivial

D: This sets child_reaper to the idle thread upon creation, so that
D: ksoftirqd's reparent_to_init call doesn't get the swapper as parent.
