-From: Gabor Juhos <juhosg@openwrt.org>
-Subject: spi-fsl-espi: avoid frequent high order allocations
-
-The driver allocates 64KiB of memory fro a local buffer before
-each transfer and releases that afterwards. When the memory is
-fragmented this allocation often fails and causes a warning like
-this:
-
- kworker/u2:2: page allocation failure: order:4, mode:0x10c0d0
- CPU: 0 PID: 7011 Comm: kworker/u2:2 Not tainted 3.10.24 #1
