If anyone has any objections, please let me know. ------------------ From: Tom Lendacky [ Upstream commit 472cfe7127760d68b819cf35a26e5a1b44b30f4e ] When allocating Rx related buffers, alloc_pages is called using an order number that is decreased until successful. A system under stress can experience failures during this allocation process resulting in a warning being issued. This message can be of concern to end users even though the failure is not fatal. Since the failure is not fatal and can occur multiple times, the driver should include the __GFP_NOWARN flag to suppress the warning message from being issued.
