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. Change-Id: I7f57a4081d9deaa0d9ccfc41a6c8daccdee3b769 Signed-off-by: José Pekkarinen <jose.pekkarinen@nokia.com>

- * This is a slightly modified SCSI sense "descriptor" format header.
- * The addition is to allow the 0x70 and 0x71 response codes. The idea
- * is to place the salient data from either "fixed" or "descriptor" sense
- * format into one structure to ease application processing.
- *
- * The original sense buffer should be kept around for those cases
- * in which more information is required (e.g. the LBA of a MEDIUM ERROR).
