Pick up some final miscellaneous updates for v6.3 including support for
communicating 'exclusive' and 'enabled' state of commands.

The command comment had grammatical errors.  In an attempt to fix those
it was noted that the comment and the query command were not in sync.

Now that the query command returns excluded and device unsupported
command information.  Update the kdoc and fix the grammatical errors.

It was pointed out that commands not supported by the device or excluded
by the kernel were being returned in cxl_query_cmd().[1]

While libcxl correctly handles failing commands, it is more efficient to
not issue an invalid command in the first place.  This can't be done
without additional information being returned from cxl_query_cmd().  In
addition, information about the availability of commands can be useful
for debugging.

Add flags to struct cxl_command_info which reflect if a command is
enabled and/or exclusive to the kernel.

Add the CXL event and interrupt support for the v6.3 update.

Resolve a conflict with the fix and move of cxl_report_and_clear() from
pci.c to core/pci.c.

A passthrough decoder is a decoder that maps only 1 target. It is a
special case because it does not impose any constraints on the
interleave-math as compared to a decoder with multiple targets. Extend
the passthrough case to multi-target-capable decoders that only have one
target selected. I.e. the current code was only considering passthrough
*ports* which are only a subset of the potential passthrough decoder
scenarios.

Not all decoders have a reset callback.

The CXL specification allows a host bridge with a single root port to
have no explicit HDM decoders. Currently the region driver assumes there
are none.  As such the CXL core creates a special pass through decoder
instance without a commit/reset callback.

Prior to this patch, the ->reset() callback was called unconditionally when
calling cxl_region_decode_reset. Thus a configuration with 1 Host Bridge,
1 Root Port, and one directly attached CXL type 3 device or multiple CXL
type 3 devices attached to downstream ports of a switch can cause a null
pointer dereference.

Before the fix, a kernel crash was observed when we destroy the region, and
a pass through decoder is reset.

The issue can be reproduced as below,
    1) create a region with a CXL setup which includes a HB with a
    single root port under which a memdev is attached directly.
    2) destroy the region with cxl destroy-region regionX -f.

The IRQ core expects that users of the default hardirq handler specify
IRQF_ONESHOT to keep interrupts disabled until the threaded handler
runs. That meets the CXL driver's expectations since it is an edge
triggered MSI and this flag would have been passed by default using
pci_request_irq() instead of devm_request_threaded_irq().

CXL r3.0 section 8.2.9.4.2 "Set Timestamp" recommends that the host sets
the timestamp after every Conventional or CXL Reset to ensure accurate
timestamps. This should include on initial boot up. The time base that
is being set is used by a device for the poison list overflow timestamp
and all event timestamps.  Note that the command is optional and if
not supported and the device cannot return accurate timestamps it will
fill the fields in with an appropriate marker (see the specification
description of each timestamp).

This reverts commit 7efc3b72.

We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
stalling CPU for long periods of time.  Investigation of tracepoint data
shows that compaction is stuck in repeating fast_find_migrateblock()
based migrate page isolation, and then fails to migrate all isolated
pages.

Commit 7efc3b72 ("mm/compaction: fix set skip in fast_find_migrateblock")
was suspected as it was merged in 6.1 and in theory can indeed remove a
termination condition for fast_find_migrateblock() under certain
conditions, as it removes a place that always marks a scanned pageblock
from being re-scanned.  There are other such places, but those can be
skipped under certain conditions, which seems to match the tracepoint
data.

Testing of revert also appears to have resolved the issue, thus revert
the commit until a more robust solution for the original problem is
developed.

It's also likely this will fix qemu stalls with 6.1 kernel reported in
Link 2, but that is not yet confirmed.

Commit 2aeaf663 introduced strict checking for variable length
payload size validation. The payload length of received data must
match the size of the requested data by the caller except for the case
where the min_out value is set.

The Get Log command does not have a header with a length field set.
The Log size is determined by the Get Supported Logs command (CXL 3.0,
8.2.9.5.1). However, the actual size can be smaller and the number of
valid bytes in the payload output must be determined reading the
Payload Length field (CXL 3.0, Table 8-36, Note 2).

Two issues arise: The command can successfully complete with a payload
length of zero. And, the valid payload length must then also be
consumed by the caller.

Change cxl_xfer_log() to pass the number of payload bytes back to the
caller to determine the number of log entries. Implement the payload
handling as a special case where mbox_cmd->size_out is consulted when
cxl_internal_send_cmd() returns -EIO. A WARN_ONCE() is added to check
that -EIO is only returned in case of an unexpected output size.

Logs can be bigger than the maximum payload length and multiple Get
Log commands can be issued. If the received payload size is smaller
than the maximum payload size we can assume all valid bytes have been
fetched. Stop sending further Get Log commands then.

On that occasion, change debug messages to also report the opcodes of
supported commands.

The variable payload commands GET_LSA and SET_LSA are not affected by
this strict check: SET_LSA cannot be broken because SET_LSA does not
return an output payload, and GET_LSA never expects short reads.

If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then
copy-up should fail, just like it would fail if the mounter task was doing
the copy using "cp -a".

There's a corner case where the "cp -a" would succeed but copy up fail: if
there's a mapping of the invalid uid/gid (65534 by default) in the user
namespace.  This is because stat(2) will return this value if the mapping
doesn't exist in the current user_ns and "cp -a" will in turn be able to
create a file with this uid/gid.

This behavior would be inconsistent with POSIX ACL's, which return -1 for
invalid uid/gid which result in a failed copy.

For consistency and simplicity fail the copy of the st_uid/st_gid are
invalid.
