Fix the STI console to be able to execute either the 64-bit STI ROM code
or the 32-bit STI ROM code.
This is necessary on 64-bit only machines (e.g. C8000 workstation) which
otherwise won't show the STI text console with HP graphic cards like
Visualize-FX5/FX10/FXe.
Note that when calling 32-bit code from a 64-bit kernel one needs to
copy contents on the CPU stack from high memory down below the 4GB
limit.

Some 64-bit machines require us to call the STI ROM in 64-bit mode, e.g.
with the VisFXe graphic card.
This patch allows drivers to use such 64-bit calling conventions.

As already mentioned in my merge message for the 'expand-stack' branch,
we have something like 24 different versions of the page fault path for
all our different architectures, all just _slightly_ different due to
various historical reasons (usually related to exactly when they
branched off the original i386 version, and the details of the other
architectures they had in their history).
And a few of them had some silly mistake in the conversion.
Most of the architectures call the faulting address 'address' in the
fault path. But not all. Some just call it 'addr'. And if you end up
doing a bit too much copy-and-paste, you end up with the wrong version
in the places that do it differently.
In this case it was csky.

In commit 8d7071af89 ("mm: always expand the stack with the mmap write
lock held") I tried to deal with the remaining odd page fault handling
cases. The oddest one is ia64, which has stacks that grow both up and
down. And because ia64 was _so_ odd, I asked people to verify the end
result.
But a close second oddity is parisc, which is the only one that has a
main stack growing up (our "CONFIG_STACK_GROWSUP" config option). But
it looked obvious enough that I didn't worry about it.
I should have worried a bit more. Not because it was particularly
complex, but because I just used the wrong variable name.
The previous vma isn't called "prev", it's called "prev_vma". Blush.

The sparc32 conversion to lock_mm_and_find_vma() in commit a050ba1e74
("mm/fault: convert remaining simple cases to lock_mm_and_find_vma()")
missed the fact that we didn't actually have a 'regs' pointer available
in the 'force_user_fault()' case.
It's there in the regular page fault path ("do_sparc_fault()"), but not
the window underflow/overflow paths.
Which is all fine - we can just pass in a NULL pointer. The register
state is only used to avoid deadlock with kernel faults, which is not
the case for any of these register window faults.

The objtool merge in commit 6f612579be ("Merge tag 'objtool-core ...")
generated a semantic conflict that was not resolved.
The btrfs_assertfail() entry was removed from the noreturn list in
commit b831306b3b ("btrfs: print assertion failure report and stack
trace from the same line") because btrfs_assertfail() was changed from a
noreturn function into a macro.
The noreturn list was then moved from check.c to noreturns.h in commit
6245ce4ab6 ("objtool: Move noreturn function list to separate file"),
and should be removed from that post-merge as well.
Do it explicitly.

its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
also updated.
- SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
There are (very limited) cases where kmem_cache merging is
undesirable, and existing ways to prevent it are hacky. Introduce a
new flag to do that cleanly and convert the existing hacky users.
Btrfs plans to use this for debug kernel builds (that use case is
always fine), networking for performance reasons (that should be very
rare).
- Replace the usage of weak PRNGs (David Keisar Schmidt):
In addition to using stronger RNGs for the security related features,
the code is a bit cleaner.
- Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
zhaoxinchao)

The largest branch is a conversion of the omap platform
to use GPIO descriptors throughout the tree, for any devices that
are not fully converted to devicetree.
The Samsung Exynos platform gains back support for the Exynos4212
chip that was previously unused and removed but is now used for
the Samsung Galaxy Tab3.

There are two new SoC families this time, and both appear fairly similar:
The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core
Cortex-A35 based chips for the low-power industrial embedded market,
and they mark the first 64-bit product in a widely used family of 32-bit
Arm MCUs and SoCs.
The way into the kernel is completely different here: The team at ST has
a long history of working upstream with their STM32MP1 and other SoCs,
and they produced a complete port to arm64 together with the initial
announcement. Nuvoton also has multiple SoC product lines with current
or previous upstream support, but those are maintained by third parties
and are unrelated. The patch series from Nuvoton's Jacky Huang had to
go through many revisisions to get to this point and is still missing
a few drivers including the serial port for the moment.
The branch contains the devicetree files as well as all the code changes,
in order to have something that can be tested standalone.

The biggest change this time is for the 32-bit devicetree files, which
are all moved to a new location, using separate subdirectories for each
SoC vendor, following the same scheme that is used on arm64, mips and
riscv. This has been discussed for many years, but so far we never did
this as there was a plan to move the files out of the kernel entirely,
which has never happened.
The impact of this will be that all external patches no longer apply,
and anything depending on the location of the dtb files in the build
directory will have to change. The installed files after 'make
dtbs_install' keep the current location.
There are six added SoCs here that are largely variants of previously
added chips. Two other chips are added in a separate branch along
with their device drivers.
* The Samsung Exynos 4212 makes its return after the Samsung Galaxy
Express phone is addded at last. The SoC support was originally
added in 2012 but removed again in 2017 as it was unused at the time.
* Amlogic C3 is a Cortex-A35 based smart IP camera chip
* Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
the still common MSM8916 (Snapdragon 410) phone chip that has been
supported for a long time.
* Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
laptop chips, used in the Lenovo Flex 5G, which is added along with
the reference board.
* Qualcomm SDX75 is the latest generation modem chip that is used
as a peripherial in phones but can also run a standalone Linux. Unlike
the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
* Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the Xuantie
C910 core, a step up from all previously added rv64 chips.
All of the above come with reference board implementations, those included
there are 39 new board files, but only five more 32-bit this time, probably
a new low:
* Marantec Maveo board based on dhcor imx6ull module
* Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
* Epson Moverio BT-200 AR glasses based on TI OMAP4
* PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
* ICnova ADB4006 board based on Allwinner A20
On the 64-bit side, there are also fewer addded machines than
we had in the recent releases:
* Three boards based on NXP i.MX8: Emtop SoM & Baseboard,
NXP i.MX8MM EVKB board and i.MX8MP based Gateworks Venice
gw7905-2x device.
* NVIDIA IGX Orin and Jetson Orin Nano boards, both based on
tegra234
* Qualcomm gains support for 6 reference boards on various members
of their IPQ networking SoC series, as well as the Sony Xperia M4
Aqua phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board
on top of the various reference platforms for their new chips.
* Rockchips support for several newer boards: Indiedroid Nova (rk3588),
Edgeble Neural Compute Module 6B (rk3588), FriendlyARM NanoPi R2C
Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn Fastrhino R66S/R68S
(rk3568)
* TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex Verdin
family with AM62 COM, carrier and dev boards
Other changes to existing boards contain the usual minor improvements
along with
* continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names
* support for devicetree overlays on at91, bcm283x
* significant additions to existing SoC support on mediatek, qualcomm,
ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST STM32MP1
As usual, a lot more detail is available in the individual merge
commits.

time, probably a new low:
- Marantec Maveo board based on dhcor imx6ull module
- Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
- Epson Moverio BT-200 AR glasses based on TI OMAP4
- PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
- ICnova ADB4006 board based on Allwinner A20
On the 64-bit side, there are also fewer addded machines than we had
in the recent releases:
- Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.
- NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234
- Qualcomm gains support for 6 reference boards on various members of
their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
of the various reference platforms for their new chips.
- Rockchips support for several newer boards: Indiedroid Nova
(rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
Fastrhino R66S/R68S (rk3568)
- TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
Verdin family with AM62 COM, carrier and dev boards
Other changes to existing boards contain the usual minor improvements
along with
- continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names
- support for devicetree overlays on at91, bcm283x
- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1
As usual, a lot more detail is available in the individual merge
