Hi Linus,

Please pull some more powerpc fixes for 5.13.

It's not obvious from the diff, but the seccomp_bpf.c change is entirely inside a
__powerpc__ ifdef.

cheers

  powerpc/64s/syscall: Fix ptrace syscall info with scv syscalls (2021-05-21 00:58:56 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.13 #4

Fix breakage of strace (and other ptracers etc.) when using the new scv ABI (Power9 or
later with glibc >= 2.33).

Fix early_ioremap() on 64-bit, which broke booting on some machines.

Thanks to: Dmitry V. Levin, Nicholas Piggin, Alexey Kardashevskiy, Christophe Leroy.
