There was an issue with the backport compat layer in yesterday's snapshot, causing issues on certain (mostly Atom) Intel chips on kernels older than 4.2, due to the use of xgetbv without checking cpu flags for xsave support. This manifested itself simply at module load time. Indeed it's somewhat tricky to support 33 different kernel versions (3.10+), plus weird distro frankenkernels. If OpenWRT doesn't support < 4.2, you probably don't need to apply this. But it also can't hurt, and probably best to stay updated. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
