4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Huazhong Tan <tanhuazh...@huawei.com>
[ Upstream commit 3ed614dce3ca9912d22be215ff0f11104b69fe62 ]
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.
Fixes: 6fe6611ff275 ("net: add Hisilicon Network Subsystem hnae framework
support")
