[ Upstream commit cf8dd57bd0d62133e4ed9e1ad83af994fac34da5 ]
Some drivers have not been built as they gained dependencies in kconfig but those
dependencies were not added to the defconfig.
The MSM pinctrl drivers fell out of the defconfig as of commit be117ca32261
("pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a
selected config"). Add PINCTRL_MSM so these stay enabled.
EDAC depends on RAS, so enable it to ensure the EDAC drivers stay
enabled.

It must be set to y and not a module as the test driver VIDEO_VIVID
requires it to be built in.

[ Upstream commit 4348cc10da6377a86940beb20ad357933b8f91bb ]
Without a sensor node, the ISC will simply fail to probe, as the
corresponding port node is missing.
It is then logical to disable the node in the devicetree.
If we add a port with a connection to a sensor endpoint, ISC can be enabled.

While debugging an issue we've found that $DEBUGFS/block/$disk/state
doesn't decode QUEUE_FLAG_HCTX_ACTIVE but only displays its numerical
value.
Add QUEUE_FLAG(HCTX_ACTIVE) to the blk_queue_flag_name array so it'll get
decoded properly.

From: Jan Beulich <jbeulich@suse.com>
[ Upstream commit 9172b5c4a778da1f855b2e3780b1afabb3cfd523 ]
Like xen_start_flags, xen_domain_type gets set before .bss gets cleared.
Hence this variable also needs to be prevented from getting put in .bss,
which is possible because XEN_NATIVE is an enumerator evaluating to
zero. Any use prior to init_hvm_pv_info() setting the variable again
would lead to wrong decisions; one such case is xenboot_console_setup()
when called as a result of "earlyprintk=xen".
Use __ro_after_init as more applicable than either __section(".data") or
__read_mostly.

* [PATCH AUTOSEL 5.14 07/17] r8152: avoid to resubmit rx immediately

[ Upstream commit baf33d7a75642b4b38a87fdf1cd96b506df4849f ]
For the situation that the disconnect event comes very late when the
device is unplugged, the driver would resubmit the RX bulk transfer
after getting the callback with -EPROTO immediately and continually.
Finally, soft lockup occurs.
This patch avoids to resubmit RX immediately. It uses a workqueue to
schedule the RX NAPI. And the NAPI would resubmit the RX. It let the
disconnect event have opportunity to stop the submission before soft
lockup.

[ Upstream commit 012e974501a270d8dfd4ee2039e1fdf7579c907e ]
Rebooting xtensa images loaded with the '-kernel' option in qemu does
not work. When executing a reboot command, the qemu session either hangs
or experiences an endless sequence of error messages.
Kernel panic - not syncing: Unrecoverable error in exception handler
Reset code jumps to the CPU restart address, but Linux can not recover
from there because code and data in the kernel init sections have been
discarded and overwritten at this point.
XTFPGA platforms have a means to reset the CPU by writing 0xdead into a
specific FPGA IO address. When used in QEMU the kernel image loaded with
the '-kernel' option gets restored to its original state allowing the
machine to boot successfully.
Use that mechanism to attempt a platform reset. If it does not work,
fall back to the existing mechanism.

[ Upstream commit c20106944eb679fa3ab7e686fe5f6ba30fbc51e5 ]
If nfsd has existing listening sockets without any processes, then an error
returned from svc_create_xprt() for an additional transport will remove
those existing listeners. We're seeing this in practice when userspace
attempts to create rpcrdma transports without having the rpcrdma modules
present before creating nfsd kernel processes. Fix this by checking for
existing sockets before calling nfsd_destroy().

[ Upstream commit 4549c3ea3160fa8b3f37dfe2f957657bb265eda9 ]
Add a helper to check if a given offset is within the branch range for a
powerpc conditional branch instruction, and update some sites to use the
new helper.

Emit similar instruction sequences to commit a048a07d7f4535
("powerpc/64s: Add support for a store forwarding barrier at kernel
entry/exit") when encountering BPF_NOSPEC.
Mitigations are enabled depending on what the firmware advertises. In
particular, we do not gate these mitigations based on current settings,
just like in x86. Due to this, we don't need to take any action if
mitigations are enabled or disabled at runtime.

From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 951cd3a0866d29cb9c01ebc1d9c17590e598226e ]
Compile-testing drivers that require access to a firmware layer
fails when that firmware symbol is unavailable. This happened
twice this week:
- My proposed to change to rework the QCOM_SCM firmware symbol
broke on ppc64 and others.
- The cs_dsp firmware patch added device specific firmware loader
into drivers/firmware, which broke on the same set of
architectures.
We should probably do the same thing for other subsystems as well,
but fix this one first as this is a dependency for other patches
getting merged.

[ Upstream commit 951cd3a0866d29cb9c01ebc1d9c17590e598226e ]
Compile-testing drivers that require access to a firmware layer
fails when that firmware symbol is unavailable. This happened
twice this week:
- My proposed to change to rework the QCOM_SCM firmware symbol
broke on ppc64 and others.
- The cs_dsp firmware patch added device specific firmware loader
into drivers/firmware, which broke on the same set of
architectures.
We should probably do the same thing for other subsystems as well,
but fix this one first as this is a dependency for other patches
getting merged.

This seems *way* too invasive a change for stable. It exposes code to
building on entire new architectures.
