Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
"This introduces a generic TEE framework in the kernel, to handle
trusted environemtns (security coprocessor or software implementations
such as OP-TEE/TrustZone). I'm sending it separately from the other
arm-soc driver changes to give it a little more visibility, once the
subsystem is merged, we will likely keep this in the arm₋soc drivers
branch or have the maintainers submit pull requests directly,
depending on the patch volume.
I have reviewed earlier versions in the past, and have reviewed the
latest version in person during Linaro Connect BUD17.
Here is my overall assessment of the subsystem:
- There is clearly demand for this, both for the generic
infrastructure and the specific OP-TEE implementation.
- The code has gone through a large number of reviews, and the review
comments have all been addressed, but the reviews were not coming
up with serious issues any more and nobody volunteered to vouch for
the quality.
- The user space ioctl interface is sufficient to work with the
OP-TEE driver, and it should in principle work with other TEE
implementations that follow the GlobalPlatform[1] standards, but it
might need to be extended in minor ways depending on specific
requirements of future TEE implementations
- The main downside of the API to me is how the user space is tied to
the TEE implementation in hardware or firmware, but uses a generic
way to communicate with it. This seems to be an inherent problem
with what it is trying to do, and I could not come up with any
better solution than what is implemented here.
For a detailed history of the patch series, see
https://lkml.org/lkml/2017/3/10/1277"

The problem is that executing the jobs in the right order doesn't give you the right result
because consecutive jobs executed on the same engine are pipelined.
In other words job B does it buffer read before job A has written it's result.

Pull more ACPI updates from Rafael Wysocki:
"These update the ACPICA code in the kernel to upstream revision
20170303 which adds a few minor fixes and improvements, update ACPI
SoC drivers with new device IDs, platform-related information and
similar, fix the register information in the xpower PMIC driver,
introduce a concept of "always present" devices to the ACPI device
enumeration code and use it to fix a problem with one platform, and
fix a system resume issue related to power resources.
Specifics:
- Update the ACPICA code in the kernel to upstream revision 20170303
which includes:
* Minor fixes and improvements in the core code (Bob Moore,
Seunghun Han).
* Debugger fixes (Colin Ian King, Lv Zheng).
* Compiler/disassembler improvements (Bob Moore, David Box, Lv
Zheng).
* Build-related update (Lv Zheng).
- Add new device IDs and platform-related information to the ACPI
drivers for Intel (LPSS) and AMD (APD) SoCs (Hanjun Guo, Hans de
Goede).
- Make it possible to quirk ACPI-enumerated devices as "always
present" on platforms where they are incorrectly reported as not
present by the AML and add the INT0002 device ID to the list of
"always present" devices (Hans de Goede).
- Fix the register information in the xpower PMIC driver and add
comments to map the registers to symbols used by AML to it (Hans de
Goede).
- Move the code turning off unused ACPI power resources during system
resume to a point after all devices have been resumed to avoid
issues with power resources that do not behave as expected (Hans de
Goede)"

some refcount_t conversion patches from Elena and a patch for an
ancient open() flags handling bug from Alexander"

and DT, so a handful of various tweaks there, removal of some old
stale support, etc.
Atmel AT91:
- Fixup of various power management related pieces
- Move of SoC detection to a drivers/soc driver instead
ST Micro STM32:
- New SoC support: STM32H743

There is no point to ask how many device-dax instances the kernel should
support. Since we are already using a dynamic major number, just allow
the max number of minors by default and be done. This also fixes the
fact that the proposed max for the NR_DEV_DAX range was larger than what
could be supported by alloc_chrdev_region().

PFs and VFs share the same structure of NDOs today,
and the VFs explicitly fails the ndo_xdp() callback stating
it doesn't support XDP.
This results in lots of:
[qede_xdp:1032(enp131s2)]VFs don't support XDP
------------[ cut here ]------------
WARNING: CPU: 4 PID: 1426 at net/core/rtnetlink.c:1637 rtnl_dump_ifinfo+0x354/0x3c0

As every dump request for the VF interface info would fail due to
rtnl_xdp_fill() returning an error code.
To resolve this, introduce a subset of the NDOs meant for the VF
in a seperate structure and register that one instead for VFs,
and omit the ndo_xdp initialization.

When configuring the doorbell DPI address, driver aligns the start
address to 4KB [HW-pages] instead of host PAGE_SIZE.
As a result, RoCE applications might receive addresses which are

Under SRIOV resource management, extra counters are allocated to VFs
from a free pool. If that pool is empty, the ALLOC_RES command for
a counter resource fails -- and this generates a misleading error
message in the message log.
Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters --
one counter per port. For ETH ports, the RoCE driver requests an
additional counter (above the guaranteed counters). If that request
fails, the VF RoCE driver simply uses the default (i.e., guaranteed)
counter for that port.
Thus, failing to allocate an additional counter does not constitute
a problem, and the error message on the PF when this occurs should
be reduced to debug level.
Finally, to identify the situation that the reason for the failure is
that no resources are available to grant to the VF, we modified the
error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded),
which more accurately describes the error.

arch_timer_mem_find_best_frame() looks through ARCH_TIMER_MEM_MAX_FRAMES
frames even after finding matches to ensure the best frame is chosen,
which means the variable frame will point to the last valid frame but
not necessarily the best frame.
On Juno, we get the following error as the wrong frame is returned as the
best frame from arch_timer_mem_find_best_frame():
arch_timer: Unable to map frame @ 0x0000000000000000
arch_timer: Frame missing phys irq.
Failed to initialize '/timer@2a810000': -22
