Vegard Nossum 25928deeb1 ACPICA: Always create namespace nodes using acpi_ns_create_node() 
ACPICA commit 29da9a2a3f5b2c60420893e5c6309a0586d7a329

ACPI is allocating an object using kmalloc(), but then frees it
using kmem_cache_free(<"Acpi-Namespace" kmem_cache>).

This is wrong and can lead to boot failures manifesting like this:

    hpet0: 3 comparators, 64-bit 100.000000 MHz counter
    clocksource: Switched to clocksource tsc-early
    BUG: unable to handle page fault for address: 000000003ffe0018

Bisection leads to unrelated changes in slab; Vlastimil Babka
suggests an unrelated layout or slab merge change merely exposed
the underlying bug.
