For instance, the current 3.10 kernel build fails at the end with:
unused option: BRCMFMAC_PCIE
unused option: FW_LOADER_USER_HELPER_FALLBACK
unused option: KEXEC_FILE
unused option: RANDOMIZE_BASE
However, it's not obvious that only the _last_ one is actually fatal to
the build. After this change it's at least somewhat better:
warning: unused option: BRCMFMAC_PCIE
warning: unused option: FW_LOADER_USER_HELPER_FALLBACK
warning: unused option: KEXEC_FILE
error: unused option: RANDOMIZE_BASE
Adds basic support for Intel GMA3600/3650 (Intel Cedar Trail) platforms
and support for GMA600 (Intel Moorestown/Oaktrail) platforms with LVDS
ports via the gma500_gfx module.

The patch for kernel version 3.18 is already applied upstream, so we
don't need it any longer.
Without i686-build-failure.patch, the build for i686-linux fails because
it references rdtscl(), which is no longer available in Linux 4.3.0.
Patch for missing rdtscl() is from Arch Linux:
https://aur.archlinux.org/cgit/aur.git/tree/002-rdtscl.patch?h=broadcom-wl-ck

While useless for binaries within the Nix store, user xattrs are a convenient
alternative for setting PaX flags to executables outside of the store.
To use disable secure memory protections for a non-store file foo, do
$ setfattr -n user.pax.flags -v em foo
Fixed for all available 4.x series kernels.
From CVE-2016-5829:
Multiple heap-based buffer overflows in the hiddev_ioctl_usage function
in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow
local users to cause a denial of service or possibly have unspecified
other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl
call.
This enables a few features that should be useful and safe (they're
all used by the default Ubuntu kernel config), in particular zswap,
wakelocks, kernel load address randomization, userfaultfd (useful for
QEMU), paravirtualized spinlocks and automatic process group
scheduling.
Also removes some configuration conditional on kernel versions that we
no longer support.
- Add a patch to unset CONFIG_LOCALVERSION in the v7 build.
- Copy all the device trees to match the upstream names so U-Boot can
find them. (This is a hack.)
The config option DEVPTS_MULTIPLE_INSTANCES now no longer exists since
torvalds/linux@eedf265aa0.

- Some files in bin/ are now shell scripts, so skip patchelf on any
non-ELF files.
With this U-Boot can be successfully launched on a RPi 3.
