- 950-0453-Add-hid-bigbenff-to-list-of-have_special_driver-for-.patch

Make I2C built-in instead of modular as in upstream defconfig; also the
easiest way to get MFD_ARIZONA enabled, which is required by
kmod-sound-soc-rpi-cirrus.
Add missing compatible strings from
4.9/960-add-rasbperrypi-compatible.patch, using upstream names for
compute modules.
Add extra patch to enable the LEDs on lan78xx.

Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y)
Runtime-tested: bcm2708, bcm2710

+Subject: [PATCH 010/454] irq_bcm2836: Send event when onlining sleeping cores
+
+In order to reduce power consumption and bus traffic, it is sensible
+for secondary cores to enter a low-power idle state when waiting to
+be started. The wfe instruction causes a core to wait until an event
+or interrupt arrives before continuing to the next instruction.
+The sev instruction sends a wakeup event to the other cores, so call
+it from bcm2836_smp_boot_secondary, the function that wakes up the
+waiting cores during booting.
+
+It is harmless to use this patch without the corresponding change
+adding wfe to the ARMv7/ARMv8-32 stubs, but if the stubs are updated
+and this patch is not applied then the other cores will sleep forever.
+
+See: https://github.com/raspberrypi/linux/issues/1989
