[ Upstream commit 6b9785dc8b13d9fb75ceec8cf4ea7ec3f3b1edbc ]
Currently, different NFS clients can share the same DS connections, even
when they are in different net namespaces. If a containerized client
creates a DS connection, another container can find and use it. When the
first client exits, the connection will close which can lead to stalls
in other clients.
Add a net namespace pointer to struct nfs4_pnfs_ds, and compare those
value to the caller's netns in _data_server_lookup_locked() when
searching for a nfs4_pnfs_ds to match.

[ Upstream commit a032f29a15412fab9f4352e0032836d51420a338 ]
Change get_thinkpad_model_data() to check for additional vendor name
"NEC" in order to support NEC Lavie X1475JAS notebook (and perhaps
more).
The reason of this works with minimal changes is because NEC Lavie
X1475JAS is a Thinkpad inside. ACPI dumps reveals its OEM ID to be
"LENOVO", BIOS version "R2PET30W" matches typical Lenovo BIOS version,
the existence of HKEY of LEN0268, with DMI fw string is "R2PHT24W".
I compiled and tested with my own machine, attached the dmesg
below as proof of work:

[ Upstream commit ab09da75700e9d25c7dfbc7f7934920beb5e39b9 ]
Building the kernel with O= is affected by stale in-tree build artifacts.
So, if the source tree is not clean, Kbuild displays the following:
$ make ARCH=um O=build defconfig
make[1]: Entering directory '/.../linux/build'
***
*** The source tree is not clean, please run 'make ARCH=um mrproper'
*** in /.../linux
***
make[2]: *** [/.../linux/Makefile:673: outputmakefile] Error 1
make[1]: *** [/.../linux/Makefile:248: __sub-make] Error 2
make[1]: Leaving directory '/.../linux/build'
make: *** [Makefile:248: __sub-make] Error 2
Usually, running 'make mrproper' is sufficient for cleaning the source
tree for out-of-tree builds.
However, building UML generates build artifacts not only in arch/um/,
but also in the SUBARCH directory (i.e., arch/x86/). If in-tree stale
files remain under arch/x86/, Kbuild will reuse them instead of creating
new ones under the specified build directory.
This commit makes 'make ARCH=um clean' recurse into the SUBARCH directory.

[ Upstream commit fb98bd0a13de2c9d96cb5c00c81b5ca118ac9d71 ]
The SPI interface is activated before the CPOL setting is applied. In
that moment, the clock idles high and CS goes low. After a short delay,
CPOL and other settings are applied, which may cause the clock to change
state and idle low. This transition is not part of a clock cycle, and it
can confuse the receiving device.
To prevent this unexpected transition, activate the interface while CPOL
and the other settings are being applied.
