Title:
Need enough contiguous memory to support GICv3 ITS table
Status in linux package in Ubuntu:
Incomplete
Bug description:
The GICv3 ITS table needs between 36K and 56K of contiguous memory.
But, with 4K pages and a MAX_ZONEORDER of 11, we can only allocate
32K. The upstream approach to resolve this will likely be to make the
core GIC a proper device that can use the DMA API:
http://www.spinics.net/lists/arm-kernel/msg487748.html
However - that's a pretty big change, and will take a while to land.
Until that time, I propose that we bump MAX_ZONEORDER up to 13 for the
generic kernel.
