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>

+* ARC HS Performance Counters
+
+The ARC HS can be configured with a pipeline performance monitor for counting
+CPU and cache events like cache misses and hits. Like conventional PCT there
+are 100+ hardware conditions dynamically mapped to upto 32 counters.
+It also supports overflow interrupts.
+
+Required properties:
+
+- compatible : should contain
+ "snps,archs-pct"
+
+Example:
+
+pmu {
+ compatible = "snps,archs-pct";
+};

-* ARC700 incore Interrupt Controller
-
- The core interrupt controller provides 32 prioritised interrupts (2 levels)
- to ARC700 core.
-
-Properties:
-
-- compatible: "snps,arc700-intc"
-- interrupt-controller: This is an interrupt controller.
-- #interrupt-cells: Must be <1>.
-
- Single Cell "interrupts" property of a device specifies the IRQ number
- between 0 to 31
-
- intc accessed via the special ARC AUX register interface, hence "reg" property
- is not specified.
-
-Example:
-
- intc: interrupt-controller {
- compatible = "snps,arc700-intc";
- interrupt-controller;
- #interrupt-cells = <1>;
- };
