When we consider MFD which implements hotplug (e.g. USB hotplug
driver based on product and vendor IDs) functionality it turns out
that its sub-devices are correctly matched with corresponding device
tree nodes only at the first time. When physical device reboots
or is replugged (and MFD driver is disconnected and probed back
again) all sub-devices fails in mfd_add_device() with error
'Failed to locate of_node'.
The reason of that behavior is that when any MFD sub-device is
created for the first time (and matched with device tree node) it
is added to the mfd_of_node_list. It looks like this list is never
cleaned even if devices added there are intentionally removed from
the system. So when MFD device is replugged and all sub-devices
are matched with their device tree nodes again they fail as matched
nodes already exist in mfd_of_node_list. In other words current
implementation does not support MFD with hotplug feature.
This commit extends MFD core for hotplugging support by removing
appropriate OF node entry from mfd_of_node_list when corresponding
device is removed from the system. Thanks to that when device is
added once again it can be matched with its device tree node
successfully.

Several ocelot-related modules are designed for MMIO / regmaps. As such,
they often use a combination of devm_platform_get_and_ioremap_resource()
and devm_regmap_init_mmio().
Operating in an MFD might be different, in that it could be memory mapped,
or it could be SPI, I2C... In these cases a fallback to use IORESOURCE_REG
instead of IORESOURCE_MEM becomes necessary.
When this happens, there's redundant logic that needs to be implemented in
every driver. In order to avoid this redundancy, utilize a single function
that, if the MFD scenario is enabled, will perform this fallback logic.

- Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit CPUs trap on it
rather than ignoring it as they should.
- Fix ftrace when building with clang, which was broken by some refactoring.
- A couple of other minor fixes.

Merge tag '5.20-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6
Pull more cifs updates from Steve French:
- two fixes for stable, one for a lock length miscalculation, and
another fixes a lease break timeout bug
- improvement to handle leases, allows the close timeout to be
configured more safely
- five restructuring/cleanup patches
* tag '5.20-rc-smb3-client-fixes-part2' of git://git.samba.org/sfrench/cifs-2.6:
cifs: Do not access tcon->cfids->cfid directly from is_path_accessible
cifs: Add constructor/destructors for tcon->cfid
SMB3: fix lease break timeout when multiple deferred close handles for the same file.
smb3: allow deferred close timeout to be configurable
cifs: Do not use tcon->cfid directly, use the cfid we get from open_cached_dir
cifs: Move cached-dir functions into a separate file
cifs: Remove {cifs,nfs}_fscache_release_page()
cifs: fix lock length calculation
Enable multipage folio support for the afs filesystem.
Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.
Note that it does require a change to afs_write_begin() to return the
correct subpage. This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.
