From de043da0b9e71147ca610ed542d34858aadfc61c Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Fri, 18 Dec 2020 16:13:56 -0800 Subject: RISC-V: Fix usage of memblock_enforce_memory_limit memblock_enforce_memory_limit accepts the maximum memory size not the maximum address that can be handled by kernel. Fix the function invocation accordingly.
