From 9a59633411727ad7dde49915a4e37a3621177ae3 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Sat, 22 Sep 2018 21:09:55 +0530 Subject: arm64/numa: Report correct memblock range for the dummy node [ Upstream commit 77cfe950901e5c13aca2df6437a05f39dd9a929b ] The dummy node ID is marked into all memory ranges on the system. So the dummy node really extends the entire memblock.memory. Hence report correct extent information for the dummy node using memblock range helper functions instead of the range [0LLU, PFN_PHYS(max_pfn) - 1)].
