Some stability changes to improve ION robustness and a perf related
change to make it easier for clients to avoid unnecessary cache
maintenance, such as when buffers are clean and haven't had any CPU
access.

Liam Mark (4):
  staging: android: ion: Support cpu access during dma_buf_detach
  staging: android: ion: Restrict cache maintenance to dma mapped memory
  dma-buf: add support for mapping with dma mapping attributes
