  powerpc/8xx: Fix Oops with STRICT_KERNEL_RWX without DEBUG_RODATA_TEST (2021-11-01 21:39:03 +1100)

- ------------------------------------------------------------------
powerpc updates for 5.16

 - Enable STRICT_KERNEL_RWX for Freescale 85xx platforms.

 - Activate CONFIG_STRICT_KERNEL_RWX by default, while still allowing it to be disabled.

 - Add support for out-of-line static calls on 32-bit.

 - Fix oopses doing bpf-to-bpf calls when STRICT_KERNEL_RWX is enabled.

 - Fix boot hangs on e5500 due to stale value in ESR passed to do_page_fault().

 - Fix several bugs on pseries in handling of device tree cache information for hotplugged
   CPUs, and/or during partition migration.

 - Various other small features and fixes.
