Subject: [PATCH v2 4/4] powerpc/book3s64/radix: Make radix_mem_block_size 64bit
Date: Thu,  6 Aug 2020 21:53:29 +0530	[thread overview]
Message-ID: <20200806162329.276534-4-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20200806162329.276534-1-aneesh.kumar@linux.ibm.com>

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")
