From 3ed614dce3ca9912d22be215ff0f11104b69fe62 Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Thu, 23 Aug 2018 11:10:10 +0800 Subject: net: hns: fix length and 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 length and page_offset are u16, they will overflow. So change them to u32.
