[Linaro-acpi] [PATCH 0/3] Interrupt priority patch set

ACPI spec is x86 oriented thus it use NMI for error reporting as low latency error signalling way. Fast response to error occurrance is what ARM trying to satisfy using interrupt prioritization since there is no NMI direct equivalent for ARM architecture.

Patch set are divided into three step: 1. Create generic code responsible for setting interrupt priority. 2. Use it in interrupt setup. 3. Example of interrupt controller priority mapping for GIC platform dependent code.

Patch set tries to meet requirements like: - not breaking existing code - easy to expand to new priority levels - easy to map generic priority levels to platform dependent priority values
