From c47e1a1cb6d473172d4d9c24056960bd542dc56c Mon Sep 17 00:00:00 2001 From: Guo Ren Date: Wed, 20 Jan 2021 17:21:57 +0800 Subject: csky: Fixup pfn_valid error with wrong max_mapnr The max_mapnr is the number of PFNs, not absolute PFN offset. Using set_max_mapnr API instead of setting the value directly.
