Hi, 5.15.156-rc1 is running fine on a Netgear GS108T v3 (the SoC is a 
Realtek RTL8380M, which has a MIPS 4KEc core).

Note, if you respond with a "Tested-by:" type line, my tools will pick
it up and add it to the final version commit in the tree when it is
made, if you want.

Results from Linaro’s test farm.
No regressions on arm64, arm, x86_64, and i386.

Tested-by: Linux Kernel Functional Testing <lkft@linaro.org>

NOTE:
[my two cents]

The arm64 kernel boot log is getting new CPU features as kernel page table
isolation forced OFF by mitigations=off on following devices / qemu / fvp.
  * bcm2711-rpi-4-b
  * fvp-aemva
  * Juno-r2
  * qemu-arm64
  * rk3399-rock-pi-4b

This cpu features message began with the latest stable-rc versions:
 * 6.8.7-rc1
 * 6.6.28-rc1
 * 6.1.87-rc1
 * 5.15.156-rc1
