scsi: lpfc: Skip issuing ADISC when node is in NPR state
When a node moves to NPR state due to a device recovery event, the
nlp_fc4_types in the node are cleared. An ADISC received for a node in the
NPR state triggers an ADISC. Without fc4 types being known, the calls to
register with the transport are no-op'd, thus no additional references are
placed on the node by transport re-registrations. A subsequent RSCN could
trigger another unregister request, which will decrement the reference
counts, leading to the ref count hitting zero and the node being freed
while futher discovery on the node is being attempted by the RSCN event
handling.
Fix by skipping the trigger of an ADISC when in NPR state. The normal ADISC
process will kick off in the regular discovery path after receiving a
response from name server.

scsi: lpfc: Skip reg_vpi when link is down for SLI3 in ADISC cmpl path
During RSCN storms, some instances of LIP on SLI-3 adapters lead to a
situation where FLOGIs keep failing with firmware indicating an illegal
command error code. This situation was preceded by an ADISC completion
that was processed while the link was down. This path on SLI-3 performs a
CLEAR_LA and attempts to activate a VPI with REG_VPI. Later, as the FLOGI
completes, it's no longer in sync with the VPI state. In SLI-3 it is
illegal to have an active VPI during FLOGI.
Resolve by circumventing the SLI-3 path that performs the CLEAR_LA and
REG_VPI. The path will be taken after the FLOGI after the next Link Up.

scsi: lpfc: Delay unregistering from transport until GIDFT or ADISC completes
On an RSCN event, the nodes specified in RSCN payload and in MAPPED state
are moved to NPR state in order to revalidate the login. This triggers an
immediate unregister from SCSI/NVMe backend. The assumption is that the
node may be missing. The re-registration with the backend happens after
either relogin (PLOGI/PRLI; if ADISC is disabled or login truly lost) or
when ADISC completes successfully (rediscover with ADISC enabled).
However, the NVMe-FC standard provides for an RSCN to be triggered when
the remote port supports a discovery controller and there was a change
of discovery log content. As the remote port typically also supports
storage subsystems, this unregister causes all storage controller
connections to fail and require reconnect.
Correct by reworking the code to ensure that the unregistration only occurs
when a login state is truly terminated, thereby leaving the NVMe storage
controllers in place.
The changes made are:
- Retain node state in ADISC_ISSUE when scheduling ADISC ELS retry.
- Do not clear wwpn/wwnn values upon ADISC failure.
- Move MAPPED nodes to NPR during RSCN processing, but do not unregister
with transport. On GIDFT completion, identify missing nodes (not marked
NLP_NPR_2B_DISC) and unregister them.
- Perform unregistration for nodes that will go through ADISC processing
if ADISC completion fails.
- Successful ADISC completion will move node back to MAPPED state.

Kbuild: lto: fix module versionings mismatch in GNU make 3.X
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.

perf probe: Fix add event failure when running 32-bit perf in a 64-bit kernel
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"

As a result, upper 32 bits of address read from kernel are truncated, an

Change data type of "address" variable to u64 and change corresponding

Revert "mm/slub: use stackdepot to save stack trace in objects"
This reverts commit
788691464c29455346dc613a3b43c2fb9e5757a4.
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.

ARM: multi_v7_defconfig: Make NOP_USB_XCEIV driver built-in
The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has
been a "regression source" a lot of times. The last case is breakage of
USB mass storage boot has been commit
e590474768f1 ("driver core: Set
fw_devlink=on by default") for multi_v7_defconfig. As long as
NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing
endlessly and prevent booting from USB mass storage device. So make
the driver built-in as in bcm2835_defconfig and arm64/defconfig.

The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly

The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
