- Revert "Revert "softirq: Let ksoftirqd do its job""
- ASoC: cs4265: SOC_SINGLE register value error fix
- Revert "ASoC: cs4265: SOC_SINGLE register value error fix"
- Revert "net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends"
- Revert "Revert "net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends""

Patches dropped after rebase:

- 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 209/454] ASoC: pcm512x: revert downstream changes
+
+This partially reverts commit 185ea05465aac8bf02a0d2b2f4289d42c72870b7
+which was added by https://github.com/raspberrypi/linux/pull/1152
+
+The downstream pcm512x changes caused a regression, it broke normal
+use of the 24bit format with the codec, eg when using simple-audio-card.
+
+The actual bug with 24bit playback is the incorrect usage
+of physical_width in various drivers in the downstream tree
+which causes 24bit data to be transmitted with 32 clock
+cycles. So it's not the pcm512x that needs fixing, it's the
+soundcard drivers.
