Subject: [PATCH v3 3/4] powerpc/book3s64/radix: Make radix_mem_block_size 64bit

From: "Aneesh Kumar K.V" <[email-masked]>
Date: Wed, 7 Oct 2020 17:18:35 +0530

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.

Fixes: af9d00e93a4f ("powerpc/mm/radix: Create separate mappings for hot-plugged memory")
