This is a note to let you know that I've just added the patch titled net: hns3: remove a misused pragma packed to the 5.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-hns3-remove-a-misused-pragma-packed.patch and it can be found in the queue-5.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Sat Dec 19 11:38:43 AM CET 2020 From: Huazhong Tan <tanhuazhong@xxxxxxxxxx> Date: Mon, 7 Dec 2020 15:20:25 +0800 Subject: net: hns3: remove a misused pragma packed From: Huazhong Tan <tanhuazhong@xxxxxxxxxx> [ Upstream commit 61f54de2e9194f01874d5eda12037b0978e77519 ] hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings. Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry.
