From: Rob Clark <robdclark@xxxxxxxxxxxx> This is a replacement for a previous patches[1] that was adding arm64 support for drm_clflush. I've also added a patch to solve a similar cache issue in vgem. The first few patches just export arch_sync_dma_for_*(). Possibly instead the EXPORT_SYMBOL_GPL() should be somewere central, rather than per-arch (but where would make sense?) The fourth adds (and exports) these ops for arch/arm. (Arnd Bergmann mentioned on IRC that Christoph Hellwig was working on this already for arch/arm which could replace the fourth patch.) The last two patches actually fix things.
