| |
From: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com>
commit ec72024e35dddb88a81e40071c87ceb18b5ee835 upstream.
Similar to commit 89c140bbaeee ("pseries: Fix 64 bit logical memory block panic") make sure different variables tracking lmb_size are updated to be 64 bit.
This was found by code audit.
