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>

+Description: (RW) Configure MSC operating mode:
+ - "single", for contiguous buffer mode (high-order alloc);
+ - "multi", for multiblock mode;
+ - "ExI", for DCI handler mode;
+ - "debug", for debug mode.
+ If operating mode changes, existing buffer is deallocated,
+ provided there are no active users and tracing is not enabled,
+ otherwise the write will fail.

+Description: (RW) Configure MSC buffer size for "single" or "multi" modes.
+ In single mode, this is a single number of pages, has to be
+ power of 2. In multiblock mode, this is a comma-separated list
+ of numbers of pages for each window to be allocated. Number of
+ windows is not limited.
+ Writing to this file deallocates existing buffer (provided
+ there are no active users and tracing is not enabled) and then
+ allocates a new one.
