Pull SoC devicetree updates from Arnd Bergmann:
"A number of SoC platforms are adding modernized variants of their
already supported chips time, with a total of 12 new SoCs, and two
older SoC getting removed:
- Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores
- Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but
largely identical.
- Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and
IOT (QC7790S/M) workloads
- Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53
cores
- Qualcomm apq8084 and ipq806x had only rudimentary support but no
actual products using them, so they are now gone.
- Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using
the Samsung SoC platform but now with Cortex-A55 cores
- ARM Zena is a virtual platform in FVP using Cortex-A720AE cores,
with additional versions planned to be merged in the future.
- ARM corstone-1000-a320 is a reference platform for IOT, using
low-end Cortex-A320 cores
- Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x
series of networking SoCs
- Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU
cores
- Rockchip RV1103B is the low-end 32-bit single-core vision processor
- Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using
Cortex-A55 cores, similar to the G3E and G3S variants we already
supported.
- NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a
significant upgrade from the older S32V and S32G series
These all come with at least one reference board or an initial product
using these, in total there are 67 newly added boards. The ones for
already supported SoCs are:
- Two more Aspeed BMC based boards
- Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs
- One Set-top-box based on Allwinner H6
- 22 additional industrial/embedded boards using 64-bit NXP i.MX8M or
i.MX9 SoCs
- 20 Qualcomm SoC based machines across all possible markets:
workstation, gaming, laptop, phone, networking, reference, ...
- Three more Rockchips rk35xx based boards
- Four variants of the Toradex Verdin using TI AM62
Other notable bits are:
- A cleanup for the 32-bit Tegra paz00 board moved the last board
specific code on Tegra into equivalent dts syntax.
- There continues to be a significant number of fixes for static
checking of dtc syntax, but it feels like this is slowing down,
hopefully getting into a state where most known issues are
addressed
- Additional hardware support for many existing boards across SoC
families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips,
STM32, Mediatek, Tegra, TI and Microchip"

- "cleanup the RAID5 XOR library" (Christoph Hellwig)
A quite far-reaching cleanup to this code. I can't do better than to
quote Christoph:
"The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography
and not using the crypto API, with the generic implementations
sitting in include/asm-generic and the arch implementations
sitting in an asm/ header in theory. The latter doesn't work for
many cases, so architectures often build the code directly into
the core kernel, or create another module for the architecture
code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric
Biggers has done for the CRC and crypto libraries later. After
that it changes to better calling conventions that allow for
smarter architecture implementations (although none is contained
here yet), and uses static_call to avoid indirection function call
overhead"

...
This is basically a copy of smb_direct_post_recv_credits(), but
there are several improvements compared to the existing function:
1. We calculate the number of missing posted buffers by getting the
difference between recv_io.credits.target and recv_io.posted.count.
Instead of the difference between recv_io.credits.target
and recv_io.credits.count, because recv_io.credits.count is
only updated once a message is send to the peer.
It was not really a problem before, because we have
a fixed number smbdirect_recv_io buffers, so the
loop terminated when smbdirect_connection_get_recv_io()
returns NULL.
But using recv_io.posted.count makes it easier to
understand.
2. In order to tell the peer about the newly posted buffer
and grant the credits, we only trigger the send immediate
when we're not granting only the last possible credit.
This is mostly a difference relative to the servers
smb_direct_post_recv_credits() implementation,
which should avoid useless ping pong messages.
