These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

-	---help---
-	  STMicroelectronics ST21NFCB core driver. It implements the chipset
-	  NCI logic and hooks into the NFC kernel APIs. Physical layers will
-	  register against it.
-
-	  To compile this driver as a module, choose m here. The module will
-	  be called st21nfcb.
-	  Say N if unsure.

-config NFC_ST21NFCB_I2C
-	tristate "NFC ST21NFCB i2c support"
-	depends on NFC_ST21NFCB && I2C
-	---help---
-	  This module adds support for the STMicroelectronics st21nfcb i2c interface.
-	  Select this if your platform is using the i2c bus.
-
-	  If you choose to build a module, it'll be called st21nfcb_i2c.
-	  Say N if unsure.
