Building a kernel with -O3 may help in hunting bugs like [1] and thus
using this switch should not be restricted to one specific arch only.
With that, lets expose it for everyone.

Subject: [PATCH 09/17] zen: Use [defer+madvise] as default khugepaged defrag
strategy
For some reason, the default strategy to respond to THP fault fallbacks
is still just madvise, meaning stall if the program wants transparent
hugepages, but don't trigger a background reclaim / compaction if THP
begins to fail allocations. This creates a snowball affect where we
still use the THP code paths, but we almost always fail once a system
has been active and busy for a while.
The option "defer" was created for interactive systems where THP can
still improve performance. If we have to fallback to a regular page due
to an allocation failure or anything else, we will trigger a background
reclaim and compaction so future THP attempts succeed and previous
attempts eventually have their smaller pages combined without stalling
running applications.
We still want madvise to stall applications that explicitely want THP,
so defer+madvise _does_ make a ton of sense. Make it the default for
interactive systems, especially if the kernel maintainer left
transparent hugepages on "always".
Reasoning and details in the original patch: https://lwn.net/Articles/711248/

Subject: [PATCH 12/17] Set vm.max_map_count to 262144 by default
The value is still pretty low, and AMD64-ABI and ELF extended numbering
supports that, so we should be fine on modern x86 systems.
This fixes crashes in some applications using more than 65535 vmas (also
affects some windows games running in wine, such as Star Citizen).

Subject: [PATCH 17/17] ZEN: intel-pstate: Implement "enable" parameter
If intel-pstate is compiled into the kernel, it will preempt the loading
of acpi-cpufreq so you can take advantage of hardware p-states without
any friction.
However, intel-pstate is not completely superior to cpufreq's ondemand
for one reason. There's no concept of an up_threshold property.
In ondemand, up_threshold essentially reduces the maximum utilization to
compare against, allowing you to hit max frequencies and turbo boost
from a much lower core utilization.
With intel-pstate, you have the concept of minimum and maximum
performance, but no tunable that lets you define, maximum frequency
means 50% core utilization. For just this oversight, there's reasons
you may want ondemand.
Lets support setting "enable" in kernel boot parameters. This lets
kernel maintainers include "intel_pstate=disable" statically in the
static boot parameters, but let users of the kernel override this
selection.
