sys/vm vm_zeroidle.c
Log:
Prevent vm_page_zero_idle_wakeup() from attempting to wake up the
page zeroing thread before it has been created. It was possible for
calls to free() very early in the boot process to panic here because
the sleep queues were not yet initialised. Specifically, sysinit_add()
running at SI_SUB_KLD would trigger this if the array of pointers
became big enough to require uma_large_alloc() allocations.
