From: Arthur Kiyanovski Date: Sun, 21 Oct 2018 18:07:14 +0300 Subject: [PATCH 16/19] net: ena: fix compilation error in xtensa architecture Origin: https://git.kernel.org/linus/00f17a8219f02139119d8b4547e032bf4888fa0d linux/prefetch.h is never explicitly included in ena_com, although functions from it, such as prefetchw(), are used throughout ena_com. This is an inclusion bug, and we fix it here by explicitly including linux/prefetch.h. The bug was exposed when the driver was compiled for the xtensa architecture. Fixes: 689b2bdaaa14 ("net: ena: add functions for handling Low Latency Queues in ena_com") Fixes: 8c590f977638 ("ena: Fix Kconfig dependency on X86") Signed-off-by: Arthur Kiyanovski Signed-off-by: David S.
