There are following issues in arm64 kdump:
1. We use crashkernel=X to reserve crashkernel below 4G, which
will fail when there is no enough low memory.
2. If reserving crashkernel above 4G, in this case, crash dump
kernel will boot failure because there is no low memory available
for allocation.
For arm64, the behavior of crashkernel=X has been changed, which
tries low allocation in DMA zone and fall back to high allocation
if it fails.
We can also use "crashkernel=X,high" to select a high region above
DMA zone, which also tries to allocate at least 256M low memory in
DMA zone
The lower bounds of crash kernel reservation and crash kernel low
reservation are different, use the consistent value CRASH_ALIGN.

IMA needs to support duplicate measurements of integrity
critical data to accurately determine the current state of that data
on the system. Further, since measurement of duplicate data is not
required for all the use cases, it needs to be policy driven.

IMA does not measure duplicate buffer data since TPM extend is a very

Add Intel tsens i2c slave driver for Intel Edge.AI Computer Vision
platforms.
The tsens i2c slave driver enables reading of on chip sensors present
in the Intel Edge.AI Computer Vision platforms. In the tsens i2c module
various junction and SoC temperatures are reported

Add xLink driver, which interfaces the xLink Core driver with the Keem
Bay VPU IPC driver, thus enabling xLink to control and communicate with
the VPU IP present on the Intel Keem Bay SoC.
Specifically the driver enables xLink Core to:
* Boot / Reset the VPU IP
* Register to

Create the /sys/bus/cxl hierarchy to enumerate:
* Memory Devices (per-endpoint control devices)
* Memory Address Space Devices (platform address ranges with
interleaving, performance, and persistence attributes)
* Memory Regions (active provisioned memory from an address
The send command allows userspace to issue mailbox commands directly to
the hardware. The driver will verify basic properties of the command and
possible inspect the input (or output) payload to determine whether or
not the command is allowed (or might taint the kernel).
The list of allowed
Add a straightforward IOCTL that provides a mechanism for userspace to
query the supported memory device commands. CXL commands as they appear
to userspace are described as part of the UAPI kerneldoc. The command
list returned via this IOCTL will contain the full set of commands that

CXL devices contain an array of capabilities that describe the
interactions software can have with the device or firmware running on
the device. A CXL compliant device must implement the device status and
the mailbox capability. A CXL compliant memory device must implement the
