CONFIG_CXL_MCE depends on CONFIG_MEMORY_FAILURE, if
CONFIG_CXL_MCE is not set, devm_cxl_register_mce_notifier() will return
an -EOPNOTSUPP, it will cause cxl_mem_state_create() failure , and then
cxl pci device probing failed. In this case, it should not break cxl pci
device probing.
Add a checking in cxl_mem_state_create() to check if the returned value
of devm_cxl_register_mce_notifier() is -EOPNOTSUPP, if yes, just output
a warning log, do not let cxl_mem_state_create() return an error.

xfs: Use abs_diff instead of XFS_ABSDIFF
Instead of creating and initializing _all_ hyp vcpus in pKVM when
the first host vcpu runs for the first time, initialize _each_
hyp vcpu in conjunction with its corresponding host vcpu.
Some of the host vcpu state (e.g., system registers and traps
values) is not initialized until the first time the host vcpu is
run. Therefore, initializing a hyp vcpu before its corresponding
host vcpu has run for the first time might not view the complete
host state of these vcpus.
Additionally, this behavior is inline with non-protected modes.

Add support for GPF flows. It is found that the CXL specification
around this to be a bit too involved from the driver side. And while
this should really all handled by the hardware, this patch takes
things with a grain of salt.
Upon respective port enumeration, both phase timeouts are set to
a max of 20 seconds, which is the NMI watchdog default for lockup
detection. The premise is that the kernel does not have enough
information to set anything better than a max across the board
and hope devices finish their GPF flows within the platform energy
budget.
Timeout detection is based on dirty Shutdown semantics. The driver
will mark it as dirty, expecting that the device clear it upon a
successful GPF event. The admin may consult the device Health and
check the dirty shutdown counter to see if there was a problem
with data integrity.

In a nvdimm interleave-set each device with an invalid or zero
serial number may cause pmem region initialization to fail, but in
cxl case such device could still set cookies of nd_interleave_set
and create a nvdimm pmem region.
This adds the validation of serial number in cxl pmem region creation.
The event of no serial number would cause to fail to set the cookie
and pmem region.
For cxl-test to work properly, always +1 on mock device's serial
number.

Some operations need to be protected by the cxl_region_rwsem in
construct_region(). Currently, construct_region() uses down_write() and
up_write() for the cxl_region_rwsem locking, so there is a goto pattern
after down_write() invoked to release cxl_region_rwsem.
construct region() can be optimized to remove the goto pattern. The
changes are creating a new function called __construct_region() which
will include all checking and operations protected by the
cxl_region_rwsem, and using guard(rwsem_write) to replace down_write()
and up_write() in __construct_region().

is required for CXL Root Ports, CXL Downstream Switch Ports, and CXL
Upstream Switch Ports.
Introduce trace logging functions for both RAS correctable and
uncorrectable errors specific to CXL PCIe Ports. Use them to trace
FW-First Protocol errors.

nvme-pci: fix stuck reset on concurrent DPC and HP
When PCIe AER is in FW-First, OS should process CXL Protocol errors from
CPER records. Introduce support for handling and logging CXL Protocol
errors.
The defined trace events cxl_aer_uncorrectable_error and
cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them
to trace FW-First Protocol errors.
Since the CXL code is required to be called from process context and
GHES is in interrupt context, use workqueues for processing.
Similar to CXL CPER event handling, use kfifo to handle errors as it
simplifies queue processing by providing lock free fifo operations.
Add the ability for the CXL sub-system to register a workqueue to
process CXL CPER protocol errors.
