I missed testing 6.1.63 so I noticed this only here, but my CI is
complaining about seeing some
[    0.000000] Couldn't find cpu id for hartid [0]
during boot.

It was caused by

    RISC-V: Don't fail in riscv_of_parent_hartid() for disabled HARTs
   =20
    [ Upstream commit c4676f8dc1e12e68d6511f9ed89707fdad4c962c ]
   =20
    The riscv_of_processor_hartid() used by riscv_of_parent_hartid() fails
    for HARTs disabled in the DT. This results in the following warning
    thrown by the RISC-V INTC driver for the E-core on SiFive boards:
   =20
    [    0.000000] riscv-intc: unable to find hart id for /cpus/cpu@0/inter=
rupt-controller
   =20
    The riscv_of_parent_hartid() is only expected to read the hartid
    from the DT so we directly call of_get_cpu_hwid() instead of calling
    riscv_of_processor_hartid().
   =20

and there is already a fix for this in Linus' tree though that you can
pick:
52909f176802 ("RISC-V: drop error print from riscv_hartid_to_cpuid()")

That's just one error print that realistically has no impact on the
operation of the system, and is not introduced by this particular
version, so
