    Subject[PATCH 5.9 279/391] powerpc/drmem: Make lmb_size 64 bit
    Date
    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.
