Hi Linus,

Please pull some more powerpc fixes for 6.1.

We had a few bad bugs on 32-bit and compat due to the introduction of syscall wrappers,
which caused syscall arguments to be handled incorrectly for some syscalls. I have at
least one report of it causing someone's root partition to fill up, presumably due to a
bad fallocate.

The asm-generic change affects RISC-V too, although Palmer didn't think there were likely
to be many compat users on RISC-V.

cheers

  powerpc/32: Select ARCH_SPLIT_ARG64 (2022-11-01 15:27:12 +1100)

- ------------------------------------------------------------------
powerpc fixes for 6.1 #4

 - Fix an endian thinko in the asm-generic compat_arg_u64() which led to syscall arguments
   being swapped for some compat syscalls.

 - Fix syscall wrapper handling of syscalls with 64-bit arguments on 32-bit kernels, which
   led to syscall arguments being misplaced.

 - A build fix for amdgpu on Book3E with AltiVec disabled.

Thanks to: Andreas Schwab, Christian Zigotzky, Arnd Bergmann.
