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.
