Pull RCU fix from Paul McKenney:
 "This fixes a pair of bugs in which an improbable but very real
  sequence of events can cause kfree_rcu() to be a bit too quick about
  freeing the memory passed to it.

  It turns out that this pair of bugs is about two years old, and so
  this is not a v6.3 regression. However: (1) It just started showing up
  in the wild and (2) Its consequences are dire, so its fix needs to go
  in sooner rather than later.

  Testing is of course being upgraded, and the upgraded tests detect
  this situation very quickly. But to the best of my knowledge right
  now, the tests are not particularly urgent and will thus most likely
  show up in the v6.5 merge window (the one after this coming one).

  Kudos to Ziwei Dai and his group for tracking this one down the hard
  way!"

Pull compute express link (cxl) fixes from Dan Williams:
 "Several fixes for driver startup regressions that landed during the
  merge window as well as some older bugs.

  The regressions were due to a lack of testing with what the CXL
  specification calls Restricted CXL Host (RCH) topologies compared to
  the testing with Virtual Host (VH) CXL topologies. A VH topology is
  typical PCIe while RCH topologies map CXL endpoints as Root Complex
  Integrated endpoints. The impact is some driver crashes on startup.

  This merge window also added compatibility for range registers (the
  mechanism that CXL 1.1 defined for mapping memory) to treat them like
  HDM decoders (the mechanism that CXL 2.0 defined for mapping
  Host-managed Device Memory). That work collided with the new region
  enumeration code that was tested with CXL 2.0 setups, and fails with
  crashes at startup.

  Lastly, the DOE (Data Object Exchange) implementation for retrieving
  an ACPI-like data table from CXL devices is being reworked for v6.4.
  Several fixes fell out of that work that are suitable for v6.3.

  All of this has been in linux-next for a while, and all reported
  issues [1] have been addressed.

  Summary:

   - Fix several issues with region enumeration in RCH topologies that
     can trigger crashes on driver startup or shutdown.

   - Fix CXL DVSEC range register compatibility versus region
     enumeration that leads to startup crashes

   - Fix CDAT endiannes handling

   - Fix multiple buffer handling boundary conditions

   - Fix Data Object Exchange (DOE) workqueue usage vs
     CONFIG_DEBUG_OBJECTS warn splats"

Currently if disk_scan_partitions() failed, GD_NEED_PART_SCAN will still
set, and partition scan will be proceed again when blkdev_get_by_dev()
is called. However, this will cause a problem that re-assemble partitioned
raid device will creat partition for underlying disk.

Test procedure:

mdadm -CR /dev/md0 -l 1 -n 2 /dev/sda /dev/sdb -e 1.0
sgdisk -n 0:0:+100MiB /dev/md0
blockdev --rereadpt /dev/sda
blockdev --rereadpt /dev/sdb
mdadm -S /dev/md0
mdadm -A /dev/md0 /dev/sda /dev/sdb

Test result: underlying disk partition and raid partition can be
observed at the same time

Note that this can still happen in come corner cases that
GD_NEED_PART_SCAN can be set for underlying disk while re-assemble raid
device.

Memory passed to kvfree_rcu() that is to be freed is tracked by a
per-CPU kfree_rcu_cpu structure, which in turn contains pointers
to kvfree_rcu_bulk_data structures that contain pointers to memory
that has not yet been handed to RCU, along with an kfree_rcu_cpu_work
structure that tracks the memory that has already been handed to RCU.
These structures track three categories of memory: (1) Memory for
kfree(), (2) Memory for kvfree(), and (3) Memory for both that arrived
during an OOM episode.  The first two categories are tracked in a
cache-friendly manner involving a dynamically allocated page of pointers
(the aforementioned kvfree_rcu_bulk_data structures), while the third
uses a simple (but decidedly cache-unfriendly) linked list through the
rcu_head structures in each block of memory.

On a given CPU, these three categories are handled as a unit, with that
CPU's kfree_rcu_cpu_work structure having one pointer for each of the
three categories.  Clearly, new memory for a given category cannot be
placed in the corresponding kfree_rcu_cpu_work structure until any old
memory has had its grace period elapse and thus has been removed.  And
the kfree_rcu_monitor() function does in fact check for this.

Except that the kfree_rcu_monitor() function checks these pointers one
at a time.  This means that if the previous kfree_rcu() memory passed
to RCU had only category 1 and the current one has only category 2, the
kfree_rcu_monitor() function will send that current category-2 memory
along immediately.  This can result in memory being freed too soon,
that is, out from under unsuspecting RCU readers.

To see this, consider the following sequence of events, in which:

o	Task A on CPU 0 calls rcu_read_lock(), then uses "from_cset",
	then is preempted.

o	CPU 1 calls kfree_rcu(cset, rcu_head) in order to free "from_cset"
	after a later grace period.  Except that "from_cset" is freed
	right after the previous grace period ended, so that "from_cset"
	is immediately freed.  Task A resumes and references "from_cset"'s
	member, after which nothing good happens.

In full detail:

					|kfree_rcu_work()

					|The "from_cset" is freed before new gp end.

// the task resumes some time later.
 |css_set_ptr->subsys[(subsys_id) <--- Caused kernel crash, because css_set_ptr is freed.

This commit therefore causes kfree_rcu_monitor() to refrain from moving
kfree_rcu() memory to the kfree_rcu_cpu_work structure until the RCU
grace period has completed for all three categories.

v2: Use helper function instead of inserted code block at kfree_rcu_monitor().

Some DT devices already have phy device configured in the DT/ACPI.
Current implementation scans for a phy unconditionally even though
there is a phy listed in the DT/ACPI and already attached.

We should check the fwnode if there is any phy device listed in
fwnode and decide whether to scan for a phy to attach to.

Syzkaller report a WARNING: "WARN_ON(!direct)" in modify_ftrace_direct().

Root cause is 'direct->addr' was changed from 'old_addr' to 'new_addr' but
not restored if error happened on calling ftrace_modify_direct_caller().
Then it can no longer find 'direct' by that 'old_addr'.

To fix it, restore 'direct->addr' to 'old_addr' explicitly in error path.
