Merge tag 'metag-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag

Pull Metag architecture changes from James Hogan:
 - Infrastructure and DT files for TZ1090 SoC (pin control drivers
   already merged via pinctrl tree).
 - Panic on boot instead of just warning if cache aliasing possible.
 - Various SMP/hotplug fixes.
 - Various other randconfig/sparse fixes.

* tag 'metag-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag: (24 commits)
  metag: move EXPORT_SYMBOL(csum_partial) to metag_ksyms.c
  metag: cpu hotplug: route_irq: preserve irq mask
  metag: kick: add missing irq_enter/exit to kick_handler()
  metag: smp: don't spin waiting for CPU to start
  metag: smp: enable irqs after set_cpu_online
  metag: use clear_tasks_mm_cpumask()
  metag: tz1090: select and instantiate pinctrl-tz1090-pdc
  metag: tz1090: select and instantiate pinctrl-tz1090
  metag: don't check for cache aliasing on smp cpu boot
  metag: panic if cache aliasing possible
  metag: *.dts: include using preprocessor
  metag: add <dt-bindings/> symlink
  metag/.gitignore: Extend the *.dtb pattern to match the dtb.S files
  metag/traps: include setup.h for the per_cpu_trap_init declaration
  metag/traps: Mark die() as __noreturn to match the declaration.
  metag/processor.h: Add missing cpuinfo_op declaration.
  metag/setup: Restrict scope for the capabilities variable
  metag/mm/cache: Restrict scope for metag_lnkget_probe
  metag/asm/irq.h: Declare init_IRQ
  metag/kernel/irq.c: Declare root_domain as static

+* Meta Processor Binding
+
+This binding specifies what properties must be available in the device tree
+representation of a Meta Processor Core, which is the root node in the tree.
+
+Required properties:
+
+    - compatible: Specifies the compatibility list for the Meta processor.
+      The type shall be <string> and the value shall include "img,meta".
+
+Optional properties:
+
+    - clocks: Clock consumer specifiers as described in
+      Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+    - clock-names: Clock consumer names as described in
+      Documentation/devicetree/bindings/clock/clock-bindings.txt.
+
+Clocks are identified by name. Valid clocks are:
+
+    - "core": The Meta core clock from which the Meta timers are derived.
+
+* Examples
+
+/ {
+        compatible = "toumaz,tz1090", "img,meta";
+
+        clocks = <&meta_core_clk>;
+        clock-names = "core";
+};
