page_fault_process_memory_range: Disable COW for VM region with zeroobj
...
This fixes ostest-mem_limits.001 which tries to anonymous-mmap 95% of
total memory. It reports a failure because:
(1) McKernel tries to allocate physically contiguous area and
fails
(2) It turns on demand-paging
(3) It tries to obtain a page from zeroobj and fails
(4) It allocates a new page
(5) It performs COW on the page, which is unnecessary

irqbalance_mck: replace extra service with service drop-in
...
Using a drop-in instead of an extra service avoids having to juggle
between both services (especially since irqbalance_mck did not have a
Conflict=irqbalance.service statement)
That way, we only have a single service to check for (irqbalance.service),
and system administrators should find this less confusing if they normally
rely on irqbalance.
The drop-in is also installed in /run so will automatically disappear in
the event of a linux crash or a reboot without shutting down mckernel
