powerpc/atomic: Use YZ constraints for DS-form instructions (2024-09-17 22:17:57 +1000)
- ------------------------------------------------------------------
powerpc updates for 6.12
- Reduce alignment constraints on STRICT_KERNEL_RWX and speed-up TLB misses on
8xx and 603.
- Replace kretprobe code with rethook and enable fprobe.
- Remove the "fast endian switch" syscall.
- Handle DLPAR device tree updates in kernel, allowing the deprecation of the
binary /proc/powerpc/ofdt interface.
