- 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:
- net: Add non-mainline source for rtl8192cu wlan
- net: Fix rtl8192cu build errors on other platforms
- brcm: adds support for BCM43341 wifi
- brcmfmac: Mute expected startup 'errors'
- ARM64: Fix build break for RTL8187/RTL8192CU wifi
- ARM64: Enable RTL8187/RTL8192CU wifi in build config
- This is the driver for Sony CXD2880 DVB-T2/T tuner + demodulator
- brcmfmac: add CLM download support
- brcmfmac: request_firmware_direct is quieter
- Sets the BCDC priority to constant 0
- brcmfmac: Disable ARP offloading when promiscuous
- brcmfmac: Avoid possible out-of-bounds read

- 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
