An important fix for the ocxl driver (opencapi driver for POWER9) is missing
in kernel 4.18. It was merged during the 4.19 merge window. The fix is already
in 18.04.1, so it needs to be added to the 18.10 kernel to avoid regression.
The commit ID is:
d497ebf5fb3a026c0817f8c96cde578787f24093
ocxl: Fix page fault handler in case of fault on dying process
Could you add it to the kernel for 18.10? Thanks
