Move the device memory allocation and deallocation commands
SW ICM memory to mlx5_core to expose this API for all
mlx5_core users.
This comes as preparation for supporting SW steering in kernel
where it will be required to allocate and register device
memory for direct rule insertion.
In addition, an API to register this device memory for future
remote access operations is introduced using the create_mkey
commands.

I've noticed that the "slab" value in memory.stat is sometimes 0, even
if some children memory cgroups have a non-zero "slab" value. The
following investigation showed that this is the result of the kmem_cache
reparenting in combination with the per-cpu batching of slab vmstats.
At the offlining some vmstat value may leave in the percpu cache, not
being propagated upwards by the cgroup hierarchy. It means that stats
on ancestor levels are lower than actual. Later when slab pages are
released, the precise number of pages is substracted on the parent
level, making the value negative. We don't show negative values, 0 is
printed instead.
To fix this issue, let's flush percpu slab memcg and lruvec stats on
memcg offlining. This guarantees that numbers on all ancestor levels
are accurate and match the actual number of outstanding slab pages.

timespec_trunc() function is used to truncate a
filesystem timestamp to the right granularity.
But, the function does not clamp tv_sec part of the
timestamps according to the filesystem timestamp limits.
The replacement api: timestamp_truncate() also alters the
signature of the function to accommodate filesystem
timestamp clamping according to flesystem limits.
Note that the tv_nsec part is set to 0 if tv_sec is not within
the range supported for the filesystem.

The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.
Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.

In the process of debugging a system with an NVDIMM that was failing to
unlock it was found that the kernel is reporting 'locked' while the DIMM
security interface is 'frozen'. Unfortunately the security state is
tracked internally as an enum which prevents it from communicating the
difference between 'locked' and 'locked + frozen'. It follows that the
enum also prevents the kernel from communicating 'unlocked + frozen'
which would be useful for debugging why security operations like 'change
passphrase' are disabled.
Ditch the security state enum for a set of flags and introduce a new
sysfs attribute explicitly for the 'frozen' state. The regression risk
is low because the 'frozen' state was already blocked behind the
'locked' state, but will need to revisit if there were cases where
applications need 'frozen' to show up in the primary 'security'
attribute. The expectation is that communicating 'frozen' is mostly a
helper for debug and status monitoring.

This patchset implements IO cost model based work-conserving
proportional controller.
While io.latency provides the capability to comprehensively prioritize
and protect IOs depending on the cgroups, its protection is binary -
the lowest latency target cgroup which is suffering is protected at
the cost of all others. In many use cases including stacking multiple
workload containers in a single system, it's necessary to distribute
IO capacity with better granularity.
One challenge of controlling IO resources is the lack of trivially
observable cost metric. The most common metrics - bandwidth and iops
- can be off by orders of magnitude depending on the device type and
IO pattern. However, the cost isn't a complete mystery. Given
several key attributes, we can make fairly reliable predictions on how
expensive a given stream of IOs would be, at least compared to other
IO patterns.
The function which determines the cost of a given IO is the IO cost
model for the device. This controller distributes IO capacity based
on the costs estimated by such model. The more accurate the cost
model the better but the controller adapts based on IO completion
latency and as long as the relative costs across differents IO
patterns are consistent and sensible, it'll adapt to the actual
performance of the device.
Currently, the only implemented cost model is a simple linear one with
a few sets of default parameters for different classes of device.
This covers most common devices reasonably well. All the
infrastructure to tune and add different cost models is already in
place and a later patch will also allow using bpf progs for cost
models.
Please see the top comment in blk-iocost.c and documentation for
more details.

There are currently two start time timestamps - start_time_ns and
io_start_time_ns. The former marks the request allocation and and the
second issue-to-device time. The planned io.weight controller needs
to measure the total time bios take to execute after it leaves rq_qos
including the time spent waiting for request to become available,
which can easily dominate on saturated devices.
This patch adds request->alloc_time_ns which records when the request
allocation attempt started. As it isn't used for the usual stats,
make it optional behind CONFIG_BLK_RQ_ALLOC_TIME and
QUEUE_FLAG_RQ_ALLOC_TIME so that it can be compiled out when there are
no users and it's active only on queues which need it even when
compiled in.

The names of the hpp_type0, hpp_type1 and hpp_type2 structs suggest that
they're related to _HPP, when in fact they're related to _HPX.
The struct hpp_type0 denotes an _HPX Type 0 setting record that supersedes
the _HPP setting record, and it has been used interchangeably for _HPP as
per the ACPI specification (see version 6.3, section 6.2.9.1) which states
that it should be applied to PCI, PCI-X and PCI Express devices, with
settings being ignored if they are not applicable.
Rename them to hpx_type0, hpx_type1 and hpx_type2 to reflect their relation
to _HPX rather than _HPP.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU changes from Paul E. McKenney:
- A one-line change that affects only Tiny RCU that is needed
by the RISC-V guys, courtesy of Christoph Hellwig.
- An update to my email address. The old one still works, at
least most of the time.

Michael Guralnik says:
====================
The series adds support for on-demand paging for DC transport.
As DC is a mlx-only transport, the capabilities are exposed to the user
using DEVX objects and later on through mlx5dv_query_device.
====================
Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies
* branch 'mlx5-odp-dc':
IB/mlx5: Add page fault handler for DC initiator WQE
IB/mlx5: Remove check of FW capabilities in ODP page fault handling
net/mlx5: Set ODP capabilities for DC transport to max

Move ASPM definitions and function prototypes from include/linux/pci-aspm.h
to include/linux/pci.h so users only need to include <linux/pci.h>:
PCIE_LINK_STATE_L0S
PCIE_LINK_STATE_L1
PCIE_LINK_STATE_CLKPM
pci_disable_link_state()
pci_disable_link_state_locked()
pcie_no_aspm()
No functional changes intended.

The MT6358 is a regulator found on boards based on MediaTek MT8183 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

Currently there's no option for the controller driver to report the
recommended Best Effort Service Latency (BESL) when operating with LPM
support. Add new fields in usb_dcd_config_params to export the
recommended baseline and deep BESL values for the function drivers to
set the proper BESL value in the BOS descriptor.

Using a linear O(N) search for timer insertion affects execution time and
D-cache footprint badly with a larger number of timers.
Switch the storage to a timerqueue which is already used for hrtimers and
alarmtimers. It does not affect the size of struct k_itimer as it.alarm is
still larger.
The extra list head for the expiry list will go away later once the expiry
is moved into task work context.
