The shm cache could contain invalid addresses if
optee_disable_shm_cache() was not called from the .shutdown hook of the
previous kernel before a kexec. These addresses could be unmapped or
they could point to mapped but unintended locations in memory.
Clear the shared memory cache, while being careful to not translate the
addresses returned from OPTEE_SMC_DISABLE_SHM_CACHE, during driver
initialization. Once all pre-cache shm objects are removed, proceed with
enabling the cache so that we know that we can handle cached shm objects
with confidence later in the .shutdown hook.

The invoke_fn hook returned OPTEE_SMC_RETURN_ETHREAD_LIMIT, indicating
that the secure world threads were all in a suspended state at the time
of the kernel crash. This intermittently prevented the kdump kernel from
booting, resulting in a failure to collect the kernel dump.
Make kernel dump collection more reliable on systems utilizing OP-TEE by
refusing to load the driver under the kdump kernel.

When building modules(CONFIG_...=m), I found some of module versions
are incorrect and set to 0.
This can be found in build log for first clean build which shows
WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed,
symbol will not be versioned.
But in second build(incremental build), the WARNING disappeared and the
module version becomes valid CRC and make someone who want to change
modules without updating kernel image can't insert their modules.
The problematic code is
+ $(foreach n, $(filter-out FORCE,$^), \
+ $(if $(wildcard $(n).symversions), \
+ ; cat $(n).symversions >> $@.symversions))
For example:
rm -f fs/notify/built-in.a.symversions ; rm -f fs/notify/built-in.a; \
llvm-ar cDPrST fs/notify/built-in.a fs/notify/fsnotify.o \
fs/notify/notification.o fs/notify/group.o ...
`foreach n` shows nothing to `cat` into $(n).symversions because
`if $(wildcard $(n).symversions)` return nothing, but actually
they do exist during this line was executed.
-rw-r--r-- 1 root root 168580 Jun 13 19:10 fs/notify/fsnotify.o
-rw-r--r-- 1 root root 111 Jun 13 19:10 fs/notify/fsnotify.o.symversions
The reason is the $(n).symversions are generated at runtime, but
Makefile wildcard function expends and checks the file exist or not
during parsing the Makefile.
Thus fix this by use `test` shell command to check the file
existence in runtime.

The commit 042da426f8 ("scripts/setlocalversion: simplify the short
version part") reduces indentation. Unfortunately, it also changes behavior
in a subtle way - if the user has empty "LOCALVERSION" variable, the plus
sign is appended to the kernel version. It wasn't appended before.
This patch reverts to the old behavior - we append the plus sign only if
the LOCALVERSION variable is not set.

The tracepoints trace_sched_stat_{wait, sleep, iowait} are not exposed to user

As a result, the command fails.
Before:
#perf sched record sleep 1

Error: File /sys/kernel/tracing/events/sched/sched_stat_wait not found.
Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?.

Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]

Solution:

The "address" member of "struct probe_trace_point" uses long data type.
If kernel is 64-bit and perf program is 32-bit, size of "address"
variable is 32 bits.
As a result, upper 32 bits of address read from kernel are truncated, an
error occurs during address comparison in kprobe_warn_out_range().
Before:
# perf probe -a schedule
schedule is out of .text, skip it.
Error: Failed to add events.
Solution:
Change data type of "address" variable to u64 and change corresponding
address printing and value assignment.
After:
# perf.new.new probe -a schedule
Added new event:
probe:schedule (on schedule)
You can now use it in all perf tools, such as:
perf record -e probe:schedule -aR sleep 1
# perf probe -l
probe:schedule (on schedule@kernel/sched/core.c)
# perf record -e probe:schedule -aR sleep 1

This second leak is caused by a strlist not being dellocated on error

Here are the patches for this week that came as the fallout of
the merge window:
- Two fixes for the NVidia memory controller driver
- multiple defconfig files get patched to turn CONFIG_FB back on
after that is no longer selected by CONFIG_DRM
- ffa and scmpi firmware drivers fixes, mostly addressing compiler
and documentation warnings
- Platform specific fixes for device tree files on ASpeed,
Renesas and NVidia SoC, mostly for recent regressions.
- A workaround for a regression on the USB PHY with devlink when
the usb-nop-xceiv driver is not available until the rootfs is
mounted.
- Device tree compiler warnings in Arm Versatile-AB

This reverts commit 788691464c.
It's not clear why, but it causes unexplained problems in entirely
unrelated xfs code. The most likely explanation is some slab
corruption, possibly triggered due to CONFIG_SLUB_DEBUG_ON. See [1].
It ends up having a few other problems too, like build errors on
arch/arc, and Geert reporting it using much more memory on m68k [3] (it
probably does so elsewhere too, but it is probably just more noticeable
on m68k).
The architecture issues (both build and memory use) are likely just
because this change effectively force-enabled STACKDEPOT (along with a
very bad default value for the stackdepot hash size). But together with
the xfs issue, this all smells like "this commit was not ready" to me.

"The bulk of the diffstat consists of changes to our uaccess routines
so that they fall back to bytewise copying prior to reporting complete
failure when the initial (multi-byte) access faults.
However, the most disappointing change here is that we've had to bump
ARCH_DMA_MINALIGN back to 128 bytes thanks to Qualcomm's "Kryo" CPU,
which ended up in the MSM8996 mobile SoC. Still, at least we're now
aware of this design and one of the hardware designers confirmed the
L2 cacheline size for us.

The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
we're updating the defconfig anyway.

This updates the Versatile Express defconfig for the changes
in the v5.14-rc1 kernel:
- The Framebuffer CONFIG_FB needs to be explicitly selected
or we don't get any framebuffer anymore. DRM has stopped to
select FB because of circular dependency.
- CONFIG_CMA options were moved around.
- CONFIG_MODULES options were moved around.
- CONFIG_CRYPTO_HW was moved around.

works fine. I don't know why this was selected in the first
place or how the Kconfig was altered so it was removed.

Pull drm fixes from Dave Airlie:
"Regular rc2 fixes though a bit more than usual at rc2 stage, people
must have been testing early or else some fixes from last week got a
bit laggy.
There is one larger change in the amd fixes to amalgamate some power
management code on the newer chips with the code from the older chips,
it should only affects chips where support was introduced in rc1 and
it should make future fixes easier to maintain probably a good idea to
merge it now.
Otherwise it's mostly fixes across the board.

Pull RCU fixes from Paul McKenney:
- fix regressions induced by a merge-window change in scheduler
semantics, which means that smp_processor_id() can no longer be used
in kthreads using simple affinity to bind themselves to a specific
CPU.
- fix a bug in Tasks Trace RCU that was thought to be strictly
theoretical. However, production workloads have started hitting this,
so these fixes need to be merged sooner rather than later.
- fix a minor printk()-format-mismatch issue introduced during the
merge window.
* 'urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu:
rcu: Fix pr_info() formats and values in show_rcu_gp_kthreads()
rcu-tasks: Don't delete holdouts within trc_wait_for_one_reader()
rcu-tasks: Don't delete holdouts within trc_inspect_reader()
refscale: Avoid false-positive warnings in ref_scale_reader()
scftorture: Avoid false-positive warnings in scftorture_invoker()
The "resets" property is not present on R-Car Gen1 SoCs.
Supporting it would require migrating from renesas,cpg-clocks to
renesas,cpg-mssr.
Reflect this in the DT bindings by removing the global "required:
resets". All SoCs that do have "resets" properties already have
SoC-specific rules making it required.

ASan reports some memory leaks when running:
# perf test "42: BPF filter"
The first of these leaks is caused by obj_buf never being deallocated in
__test__bpf.
This patch adds the missing free.

Make sure that we do not share tcp sessions of dfs mounts when
mounting regular shares that connect to same server. DFS connections
rely on a single instance of tcp in order to do failover properly in
