This patch will present the structure for the NVMeTCP offload common
layer driver. This module is added under "drivers/nvme/host/" and future
offload drivers which will register to it will be placed under
"drivers/nvme/hw".
This new driver will be enabled by the Kconfig "NVM Express over Fabrics
TCP offload commmon layer".
In order to support the new transport type, for host mode, no change is
needed.
Each new vendor-specific offload driver will register to this ULP during
its probe function, by filling out the nvme_tcp_ofld_dev->ops and
nvme_tcp_ofld_dev->private_data and calling nvme_tcp_ofld_register_dev
with the initialized struct.
The internal implementation:
- tcp-offload.h:
Includes all common structs and ops to be used and shared by offload
drivers.
- tcp-offload.c:
Includes the init function which registers as a NVMf transport just
like any other transport.

iwl-next Intel Wired LAN Driver Updates 2021-06-01
This pull request is targeting net-next and rdma-next branches.
These patches have been reviewed by netdev and rdma mailing lists[1].
This series adds RDMA support to the ice driver for E810 devices and
converts the i40e driver to use the auxiliary bus infrastructure
for X722 devices. The PCI netdev drivers register auxiliary RDMA devices
that will bind to auxiliary drivers registered by the new irdma module.

---
v3:
- ice_aq_add_rdma_qsets(), ice_cfg_vsi_rdma(), ice_[ena|dis]_vsi_rdma_qset(),
and ice_cfg_rdma_fltr() no longer return ice_status
- Remove null check from ice_aq_add_rdma_qsets()
v2:
- Added patch 'i40e: Replace one-element array with flexible-array
member'
Changes since linked review (v6):
- Removed unnecessary checks in i40e_client_device_register() and
i40e_client_device_unregister()
- Simplified the i40e_client_device_register() API

Pull Landlock LSM from James Morris:
"Add Landlock, a new LSM from Mickaël Salaün.
Briefly, Landlock provides for unprivileged application sandboxing.
From Mickaël's cover letter:
"The goal of Landlock is to enable to restrict ambient rights (e.g.
global filesystem access) for a set of processes. Because Landlock
is a stackable LSM [1], it makes possible to create safe security
sandboxes as new security layers in addition to the existing
system-wide access-controls. This kind of sandbox is expected to
help mitigate the security impact of bugs or unexpected/malicious
behaviors in user-space applications. Landlock empowers any
process, including unprivileged ones, to securely restrict
themselves.
Landlock is inspired by seccomp-bpf but instead of filtering
syscalls and their raw arguments, a Landlock rule can restrict the
use of kernel objects like file hierarchies, according to the
kernel semantic. Landlock also takes inspiration from other OS
sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD
Pledge/Unveil.
In this current form, Landlock misses some access-control features.
This enables to minimize this patch series and ease review. This
series still addresses multiple use cases, especially with the
combined use of seccomp-bpf: applications with built-in sandboxing,
init systems, security sandbox tools and security-oriented APIs [2]"

unit to IIO PMON mapping")
It is intended to provide four I/O performance metrics in MB per
each PCIe root port:
- Inbound Read: I/O devices below root port read from the host memory
- Inbound Write: I/O devices below root port write to the host memory
- Outbound Read: CPU reads from I/O devices below root port
- Outbound Write: CPU writes to I/O devices below root port
- Align CSV output for summary.
- Clarify --null use cases: Assess raw overhead of 'perf stat' or
measure just wall clock time.
- Improve readability of shadow stats.
perf record:
- Change the COMM when starting tha workload so that --exclude-perf
doesn't seem to be not honoured.
- Improve 'Workload failed' message printing events + what was
exec'ed.
- Fix cross-arch support for TIME_CONV.
perf report:
- Add option to disable raw event ordering.
- Dump the contents of PERF_RECORD_TIME_CONV in 'perf report -D'.
- Improvements to --stat output, that shows information about
PERF_RECORD_ events.
- Preserve identifier id in OCaml demangler.
perf annotate:
- Show full source location with 'l' hotkey in the 'perf annotate'
TUI.
- Add line number like in TUI and source location at EOL to the 'perf
annotate' --stdio mode.
- Add --demangle and --demangle-kernel to 'perf annotate'.
- Allow configuring annotate.demangle{,_kernel} in 'perf config'.
- Fix sample events lost in stdio mode.
perf data:
- Allow converting a perf.data file to JSON.
libperf:
- Add support for user space counter access.
- Update topdown documentation to permit rdpmc calls.
perf test:

- Cleanup 'perf test daemon' if its 'perf test' is interrupted.
- Handle metric reuse in pmu-events parsing 'perf test' entry.
- Add test for PE executable support.
- Add timeout for wait for daemon start in its 'perf test' entries.
Build:
- Enable libtraceevent dynamic linking.
- Improve feature detection output.

Pull pin control updates from Linus Walleij:
"There is a lot going on!
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls"
