With the new fortify string system, rework the memcpy to avoid this
warning:

The return value is wrong in ext4_load_and_init_journal(). The local
variable 'err' need to be initialized before goto out. The original code
in __ext4_fill_super() is fine because it has two return values 'ret'
and 'err' and 'ret' is initialized as -EINVAL. After we factor out
ext4_load_and_init_journal(), this code is broken. So fix it by directly
returning -EINVAL in the error handler path.

When opened a symlink, link name is from 'inode->i_link', but it may be
reset to a new value when revalidate the dentry. If some processes get the
link name on the race scenario, then UAF will happen on link name.

Fix this by implementing 'get_link' interface to duplicate the link name.

Pull xfs fixes from Darrick Wong:
 "Dave and I had thought that this would be a very quiet cycle, but we
  thought wrong.

  At first there were the usual trickle of minor bugfixes, but then
  Zorro pulled -rc1 and noticed complaints about the stronger memcpy
  checks w.r.t. flex arrays.

  Analyzing how to fix that revealed a bunch of validation gaps in
  validating ondisk log items during recovery, and then a customer hit
  an infinite loop in the refcounting code on a corrupt filesystem.

  So. This largeish batch of fixes addresses all those problems, I hope.

  Summary:

   - Fix a UAF bug during log recovery

   - Fix memory leaks when mount fails

   - Detect corrupt bestfree information in a directory block

   - Fix incorrect return value type for the dax page fault handlers

   - Fix fortify complaints about memcpy of xfs log item objects

   - Strengthen inadequate validation of recovered log items

   - Fix incorrectly declared flex array in EFI log item structs

   - Log corrupt log items for debugging purposes

   - Fix infinite loop problems in the refcount code if the refcount
     btree node block keys are corrupt

   - Fix infinite loop problems in the refcount code if the refcount
     btree records suffer MSB bitflips

   - Add more sanity checking to continued defer ops to prevent

Pull ARM SoC fixes from Arnd Bergmann:
 "There are not a lot of important fixes for the soc tree yet this time,
  but it's time to upstream what I got so far:

   - DT Fixes for Arm Juno and ST-Ericsson Ux500 to add missing critical
     temperature points

   - A number of fixes for the Arm SCMI firmware, addressing correctness
     issues in the code, in particular error handling and resource
     leaks.

   - One error handling fix for the new i.MX93 power domain driver

   - Several devicetree fixes for NXP i.MX6/8/9 and Layerscape chips,
     fixing incorrect or missing DT properties for MDIO controller
     nodes, CPLD, USB and regulators for various boards, as well as some
     fixes for DT schema checks.

Since commit ab51e15d ("fprobe: Introduce FPROBE_FL_KPROBE_SHARED flag
for fprobe") introduced fprobe_kprobe_handler() for fprobe::ops::func,
unregister_fprobe() fails to unregister the registered if user specifies
FPROBE_FL_KPROBE_SHARED flag.
Moreover, __register_ftrace_function() is possible to change the
ftrace_ops::func, thus we have to check fprobe::ops::saved_func instead.

To check it correctly, it should confirm the fprobe::ops::saved_func is
either fprobe_handler() or fprobe_kprobe_handler().

Commit 237405eb ("arm64: cpufeature: Force HWCAP to be based on the
sysreg visible to user-space") forced the hwcaps to use sanitised
user-space view of the id registers. However, the ID register structures
used to select few compat cpufeatures (vfp, crc32, ...) are masked and
hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32
personality.

Add the ID register structures explicitly and set the relevant entry as
visible. As these ID registers are now of type visible so make them
available in 64-bit userspace by making necessary changes in register
emulation logic and documentation.

While at it, update the comment for structure ftr_generic_32bits[] which
lists the ID register that use it.
