- Revert "mm: alloc_contig: re-allow CMA to compact FS pages"
- Revert "Revert "mm: alloc_contig: re-allow CMA to compact FS pages""
- cxd2880: CXD2880_SPI_DRV should select DVB_CXD2880 with
  MEDIA_SUBDRV_AUTOSELECT
- 950-0421-HID-hid-bigbenff-driver-for-BigBen-Interactive-PS3OF.patch
- 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 233/454] overlays: Rework sdio overlays to allow polling
+
+MMC/SD interfaces support a DT property (non-removable) that disables
+the usual polling required to detect card removal for a configuration
+that doesn't have hardware card presence detection. This property is
+required for the on-board SDIO WiFi interface, but other uses of the
+interface may want the polling to be re-enabled.
+
+'non-removable' is a boolean DT property - true if present, false if
+absent - and the overlay mechanism does not allow a property in the
+base DTB to be deleted, so if the base DTB has non-removable set
+(which is true for all WiFi-equipped Pis) then an overlay cannot
+unset it.
+
+Modify the SDIO overlays to work around this problem by disabling
+the mmc node and adding a clone to which non-removable may
+optionally be added.
+
+N.B. The default state of poll_once is still true, and the overlay
+does include a non-removable property, but setting poll_once to false
+("off") will remove the property from the overlay before it is applied.
+
