This is a note to let you know that I've just added the patch titled powerpc/powernv: Use CPU-endian hub diag-data type in pnv_eeh_get_and_dump_hub_diag() to the 4.8-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: powerpc-powernv-use-cpu-endian-hub-diag-data-type-in-pnv_eeh_get_and_dump_hub_diag.patch and it can be found in the queue-4.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From a7032132d7560a8434e1f54b71efd7fa20f073bd Mon Sep 17 00:00:00 2001 From: Gavin Shan <gwshan@xxxxxxxxxxxxxxxxxx> Date: Tue, 2 Aug 2016 14:10:30 +1000 Subject: powerpc/powernv: Use CPU-endian hub diag-data type in pnv_eeh_get_and_dump_hub_diag() From: Gavin Shan <gwshan@xxxxxxxxxxxxxxxxxx> commit a7032132d7560a8434e1f54b71efd7fa20f073bd upstream. The hub diag-data type is filled with big-endian data by OPAL call opal_pci_get_hub_diag_data(). We need convert it to CPU-endian value before using it. The issue is reported by sparse as pointed by Michael Ellerman: eeh-powernv.c:1309:21: warning: restricted __be16 degrades to integer This converts hub diag-data type to CPU-endian before using it in pnv_eeh_get_and_dump_hub_diag().
