From 27a5959308559fa6afcaa4e6cd81d25bcb2dda7c Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Thu, 23 Aug 2018 11:37:15 +0800 Subject: [PATCH] net: hns3: fix page_offset overflow when CONFIG_ARM64_64K_PAGES When enable the config item "CONFIG_ARM64_64K_PAGES", the size of PAGE_SIZE is 65536(64K). But the type of page_offset is u16, it will overflow. So change it to u32, when "CONFIG_ARM64_64K_PAGES" enabled.
