| Subject: s390/numa: set node distance to LOCAL_DISTANCE |
| |
| From: Alexander Gordeev <agordeev@linux.ibm.com> |
| |
| commit 535e4fc623fab2e09a0653fc3a3e17f382ad0251 upstream. |
| |
| The node distance is hardcoded to 0, which causes a trouble |
| for some user-level applications. In particular, "libnuma" |
| expects the distance of a node to itself as LOCAL_DISTANCE. |
| This update removes the offending node distance override. |
