Hi Alison,

Here's a branch with everything in one place:
https://github.com/shaikhkamal/linux/tree/cxl-poison-rfc-Breno-v5

(top: 9e63fdb "cxl/region: Register device poison before exposing RAM")

It's next-20260908 + Breno's hwpoison-kho v5 + this 5-patch RFC,
matching what was posted.


Thanks,
Shaikh
