Windows 2012 (non-R2) does not specify hot add region in hot add requests
and the logic in hot_add_req() is trying to find a 128Mb-aligned region
covering the request. It may also happen that host's requests are not 128Mb
aligned and the created ha_region will start before the first specified
PFN.
I'm observing the following hot add requests from the WS2012 host:
hot_add_req: start_pfn = 0x108200 count = 330752
hot_add_req: start_pfn = 0x158e00 count = 193536
hot_add_req: start_pfn = 0x188400 count = 239616
As the host doesn't specify hot add regions we're trying to create
128Mb-aligned re
With the recently introduced in-kernel memory onlining
(MEMORY_HOTPLUG_DEFAULT_ONLINE) these it no point in waiting for pages
to come online in the driver and in case the feature is disabled the 5
second wait won't help. Get rid of the waiting.

Crashes with Hyper-V balloon driver are reported with WS2012 (non-R2),
hosts I was able to identify two issues which I fix with first two patches
of this series. Patches 3 removes ol_waitevent which is not needed since
we have in-kernel memory onlining, patch 4 gets rid of ha_region_mutex
by doing
lockdep reports possible circular locking dependency when udev is used
for memory onlining:
systemd-udevd/3996 is trying to acquire lock:
((memory_chain).rwsem){.+}, at: []
__blocking_notifier_call_chain+0x4e/0xc0
but task is already holding lock:
(&dm_device.ha_region_mutex){+.+.+.},
