[PATCH 0/5] enhance configuring an ITS

This patch series makes some enhancement to ITS configuration in the following three aspects: o allocation of the ITS tables o replacing magic numbers with sensible macros o supporting ITS power down This patch series is based on linux 3.19-rc6, and tested on Hisilion ARM64 board with GICv3 ITS

[PATCH 3/5] irqchip: gicv3-its: use 64KB page as default granule

The field of page size in register GITS_BASERn might be read-only if an implementation only supports a single, fixed page size. But currently the ITS driver will throw out an error when PAGE_SIZE is less than the minimum size supported by an ITS. So addressing this problem by using 64KB pages as

[PATCH 2/5] irqchip: gicv3-its: zero itt before handling to hardware

Some kind of brain-dead implementations chooses to insert ITEes in rapid sequence of disabled ITEes, and an un-zeroed ITT will confuse ITS on judging whether an ITE is really enabled or not. Considering the implementations are still supported by the GICv3 architecture, in which ITT is not required
