-Subject: [PATCH] staging: vcsm-cma: Remove cache manipulation ioctl
- from ARM64
-
-The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
-decoder as it needs finer grained flushing control than dma_ops
-allow.
-These cache calls are not present for ARM64, therefore disable
-them. We are not actively supporting 64bit kernels at present,
-and the use case of the HEVC decoder is fairly limited.
-
