CXL rev 3.2 section 8.2.10.2.1.4 Table 8-60 defines the Memory Sparing
Event Record.
Determine if the event read is memory sparing record and if so trace the
record.
Memory device shall produce a memory sparing event record
1. After completion of a PPR maintenance operation if the memory sparing
event record enable bit is set (Field: sPPR/hPPR Operation Mode in
Table 8-128/Table 8-131).
2. In response to a query request by the host (see section 8.2.10.7.1.4)
to determine the availability of sparing resources.
The device shall report the resource availability by producing the Memory
Sparing Event Record (see Table 8-60) in which the channel, rank, nibble
mask, bank group, bank, row, column, sub-channel fields are a copy of the
values specified in the request. If the controller does not support
reporting whether a resource is available, and a perform maintenance
operation for memory sparing is issued with query resources set to 1, the
controller shall return invalid input.
Example trace log for produce memory sparing event record on completion
of a soft PPR operation,
cxl_memory_sparing: memdev=mem1 host=0000:0f:00.0 serial=3

Note: For memory sparing event record, fields 'maintenance operation
class' and 'maintenance operation subclass' are defined twice, first
in the common event record (Table 8-55) and second in the memory
sparing event record (Table 8-60). Thus those in the sparing event
record coded as reserved, to be removed when the spec is updated.

CXL spec 3.2 section 8.2.10.2.1 Table 8-55, Common Event Record format
defined new fields LD-ID and Head ID.
LD-ID: ID of logical device from where the event originated, which is
valid only if LD-ID valid flag is set to 1.
CXL spec 3.2 Section 2.4 describes, a Type 3 Multi-Logical Device (MLD)
can partition its resources into up to 16 isolated Logical Devices.
Each Logical Device is identified by a Logical Device Identifier (LD-ID)
in CXL.mem and CXL.io protocols. LD-ID is a 16-bit Logical Device
identifier applicable for CXL.io and CXL.mem requests and responses.
CXL.mem supports only the lower 4 bits of LD-ID and therefore can support
up to 16 unique LD-ID values over the link. Requests and responses
forwarded over an MLD Port are tagged with LD-ID.
Head ID: ID of the device head, from where the event originated, which is
valid only if head valid flag is set to 1.
Add updates for the above spec changes in the CXL events record and CXL
common trace event implementation.

From Dave [1]:
"""
It was a mistake to introduce core/acpi.c and putting ACPI dependency on
cxl_core when adding the extended linear cache support.
"""
Current implementation calls hmat_get_extended_linear_cache_size() of
the ACPI subsystem. That external reference causes issue running
cxl_test as there is no way to "mock" that function and ignore it when
using cxl test.
Instead of working around that using cxlrd ops and extensively
expanding cxl_test code [1], just move HMAT calls out of the core
module to cxl_acpi. Implement this by adding a @cache_size member to
struct cxl_root_decoder. During initialization the cache size is
determined and added to the root decoder object in cxl_acpi. Later on
in cxl_core the cache_size parameter is used to setup extended linear
caching.

mutex_lock_io() differs from mutex_lock() in that it may call
io_schedule() when a task must sleep waiting for the lock. This
distinction only makes sense in block I/O or memory reclaim paths,
where giving I/O a chance to make progress is useful.
At this call site, cxl_pci_mbox_send(), the mutex protects an MMIO
mailbox. The task holding the lock is not blocking I/O progress, so
calling io_schedule(), as mutex_lock_io() may do, has no practical
effect.
Although there is no functional change, using the correct locking
primitive, that more accurately reflects the semantics and intended
use of the lock, improves code clarity and avoids misleading readers
and tools.

There exists shipping platforms that bend, break, or otherwise lean on
ambiguities in the CXL specification. Without driver changes to accommodate
these deviations, end users are left without CXL subsystem RAS features.
Specifically, provisioning, error translation, and other flows require the
CXL subsystem to understand the platforms CXL topology beyond undecorated
memory address ranges.
Those isolated compatibility problems risk growing into deeper upstream
maintenance burden if different platform vendors arrive at diverging
solutions. For example, there are multiple options for resolving
low-memory-mmio intersecting large-interleave-ways CXL windows. Linux
should only entertain one solution to that problem.
Now, with the ACPI Specification Working Group, situations like this would
be resolved with the "Code First ECN" process to codify Linux expectations
in a specification. In the absence of such a process for the CXL
specification, create a file in Linux documentation to detail the
motivations, assumptions, tradeoffs, and proposals for amending
specification language.
The goal is to capture the issues such that platform vendors arrive at
compatible solutions for these problems and serve as a repository for
potential specification updates. The expectation is to update
conventions.rst along with CXL subsystem code changes to accommodate the
platform topology.

Pull tracing fix from Steven Rostedt:
- Fix possible UAF on error path in filter_free_subsystem_filters()
When freeing a subsystem filter, the filter for the subsystem is
passed in to be freed and all the events within the subsystem will
have their filter freed too. In order to free without waiting for RCU
synchronization, list items are allocated to hold what is going to be
freed to free it via a call_rcu(). If the allocation of these items
fails, it will call the synchronization directly and free after that
(causing a bit of delay for the user).
The subsystem filter is first added to this list and then the filters
for all the events under the subsystem. The bug is if one of the
allocations of the list items for the event filters fail to allocate,
it jumps to the "free_now" label which will free the subsystem
filter, then all the items on the allocated list, and then the event
filters that were not added to the list yet. But because the
subsystem filter was added first, it gets freed twice.
The solution is to add the subsystem filter after the events, and
then if any of the allocations fail it will not try to free any of
them twice
