We use dma_buf pointer cyclestate_buffer_handler in common code But since this is linux specific, we need to move this out of common code and into linux specific code Move dma_buf pointer cyclestate_buffer_handler from common channel code to struct nvgpu_channel_linux Fix all pointer accesses to this handle Move gk20a_channel_free_cycle_stats_buffer() to ioctl_channel.c since it is mostly linux specific And since gk20a_channel_free_cycle_stats_buffer() needs to be called while closing the channel, call it from nvgpu_channel_close_linux() Jira NVGPU-397 Jira NVGPU-415 Change-Id: Ifb429e49b8f7a1c9e2bc757f3efdd50b28ceca1f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1603909 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
