+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".

+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.

+Subject: [PATCH] ZEN: Input: evdev - use call_rcu when detaching client
+
+Significant time was spent on synchronize_rcu in evdev_detach_client
+when applications closed evdev devices. Switching VT away from a
+graphical environment commonly leads to mass input device closures,
+which could lead to noticable delays on systems with many input devices.
+
+Replace synchronize_rcu with call_rcu, deferring reclaim of the evdev
+client struct till after the RCU grace period instead of blocking the
+calling application.
+
+While this does not solve all slow evdev fd closures, it takes care of a
+good portion of them, including this simple test:
+
+	#include <fcntl.h>
+	#include <unistd.h>
+
+	int main(int argc, char *argv[])
+	{
+		int idx, fd;
+		const char *path = "/dev/input/event0";

+				return -1;
+			}
+			close(fd);
+		}
+		return 0;

+Subject: [PATCH] ZEN: mm: Lower the non-hugetlbpage pageblock size to reduce
+ scheduling delays
+
+The page allocator processes free pages in groups of pageblocks, where
+the size of a pageblock is typically quite large (1024 pages without
+hugetlbpage support). Pageblocks are processed atomically with the zone
+lock held, which can cause severe scheduling delays on both the CPU
+going through the pageblock and any other CPUs waiting to acquire the
+zone lock. A frequent offender is move_freepages_block(), which is used
+by rmqueue() for page allocation.
+
+As it turns out, there's no requirement for pageblocks to be so large,
+so the pageblock order can simply be reduced to ease the scheduling
+delays and zone lock contention. PAGE_ALLOC_COSTLY_ORDER is used as a
+reasonable setting to ensure non-costly page allocation requests can
+still be serviced without always needing to free up more than one
+pageblock's worth of pages at a time.
+
+This has a noticeable effect on overall system latency when memory
+pressure is elevated. The various mm functions which operate on
+pageblocks no longer appear in the preemptoff tracer, where previously
+they would spend up to 100 ms on a mobile arm64 CPU processing a
+pageblock with preemption disabled and the zone lock held.

+Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
+
+There is noticeable scheduling latency and heavy zone lock contention
+stemming from rmqueue_bulk's single hold of the zone lock while doing
+its work, as seen with the preemptoff tracer. There's no actual need for
+rmqueue_bulk() to hold the zone lock the entire time; it only does so
+for supposed efficiency. As such, we can relax the zone lock and even
+reschedule when IRQs are enabled in order to keep the scheduling delays
+and zone lock contention at bay. Forward progress is still guaranteed,
+as the zone lock can only be relaxed after page removal.
+
+With this change, rmqueue_bulk() no longer appears as a serious offender
+in the preemptoff tracer, and system latency is noticeably improved.

+Subject: [PATCH] ZEN: INTERACTIVE: dm-crypt: Disable workqueues for crypto ops
+
+Queueing in dm-crypt for crypto operations reduces performance on modern
+systems.  As discussed in an article from Cloudflare, they discovered
+that queuing was introduced because the crypto subsystem used to be
+synchronous.  Since it's now asynchronous, we get double queueing when
+using the subsystem through dm-crypt.  This is obviously undesirable and
+reduces throughput and increases latency.
+
+Disable queueing when using our Zen Interactive configuration.

+From: Mark Weiman <mark.weiman@markzz.com>
+Date: Sun, 12 Aug 2018 11:36:21 -0400
+Subject: [PATCH] pci: Enable overrides for missing ACS capabilities
+
+This an updated version of Alex Williamson's patch from:
+https://lkml.org/lkml/2013/5/30/513
+
+Original commit message follows:
+
+PCIe ACS (Access Control Services) is the PCIe 2.0+ feature that
+allows us to control whether transactions are allowed to be redirected
+in various subnodes of a PCIe topology.  For instance, if two
+endpoints are below a root port or downsteam switch port, the
+downstream port may optionally redirect transactions between the
+devices, bypassing upstream devices.  The same can happen internally
+on multifunction devices.  The transaction may never be visible to the
+upstream devices.
+
+One upstream device that we particularly care about is the IOMMU.  If
+a redirection occurs in the topology below the IOMMU, then the IOMMU
+cannot provide isolation between devices.  This is why the PCIe spec
+encourages topologies to include ACS support.  Without it, we have to
+assume peer-to-peer DMA within a hierarchy can bypass IOMMU isolation.
+
+Unfortunately, far too many topologies do not support ACS to make this
+a steadfast requirement.  Even the latest chipsets from Intel are only
+sporadically supporting ACS.  We have trouble getting interconnect
+vendors to include the PCIe spec required PCIe capability, let alone
+suggested features.
+
+Therefore, we need to add some flexibility.  The pcie_acs_override=
+boot option lets users opt-in specific devices or sets of devices to
+assume ACS support.  The "downstream" option assumes full ACS support
+on root ports and downstream switch ports.  The "multifunction"
+option assumes the subset of ACS features available on multifunction
+endpoints and upstream switch ports are supported.  The "id:nnnn:nnnn"
+option enables ACS support on devices matching the provided vendor
+and device IDs, allowing more strategic ACS overrides.  These options
+may be combined in any order.  A maximum of 16 id specific overrides
+are available.  It's suggested to use the most limited set of options
+necessary to avoid completely disabling ACS across the topology.
+Note to hardware vendors, we have facilities to permanently quirk
+specific devices which enforce isolation but not provide an ACS
+capability.  Please contact me to have your devices added and save
+your customers the hassle of this boot option.

+Subject: [PATCH] futex: Add entry point for FUTEX_WAIT_MULTIPLE (opcode 31)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add an option to wait on multiple futexes using the old interface, that
+uses opcode 31 through futex() syscall. Do that by just translation the
+old interface to use the new code. This allows old and stable versions
+of Proton to still use fsync in new kernel releases.
