Recently, our syzbot test reported NULL pointer dereference in
device_del() by injecting memory allocation fail in device_add().
For now, callers of device_add(), such as add_disk(), may ignore
device_add()'s fail and go on working. In unregister path, it will
call device_del() from del_gendisk().

We will go ahead with just adding the "__GFP_NORETRY " flag to reduce the time
it takes to fail the higher order memory allocations in case higher order pages

Given ACPICA support is needed before drivers can integrate ACPI
functionality add some module parameters as proxies.

CXL MMIO register blocks are organized by device type and capabilities.
There are Component registers, Device registers (yes, an ambiguous

On a typical end product, a vendor may choose to secure some regions in
the NAND memory which are supposed to stay intact between FW upgrades.
The access to those regions will be blocked by a secure element like
Trustzone. So the normal world software like Linux kernel should not
touch these region
The percpu_ref to gate whether cxl_memdev_ioctl() is free to use the
driver context (@cxlm) to issue I/O is overkill, implemented incorrectly
(missing a device reference before accessing the percpu_ref), and the
complexities of shutting down a percpu_ref contributed to a bug in the
error unwind in

Intel mgbe supports 2.5G mode operation when PCS is in 1000BASE-X mode.
The 2.5G mode of operation is functionally same as 1000BASE-X mode,
except that the clock rate is 2.5 times the original rate. In 2.5G mode,
the link will operate as 2500Mbps/250Mbps/25Mbps. Hence, 2.5Gbps

Once the pipeline is set in the base code, create a callback that will adapt
the ISC pipeline to each product.
Create the adapt_pipeline callback that will be used in this fashion.
