Christian König 76bf0db554 dma-buf/fence: make fence context 64 bit v2 ... Fence contexts are created on the fly (for example) by the GPU scheduler used in the amdgpu driver as a result of an userspace request. Because of this userspace could in theory force a wrap around of the 32bit context number if it doesn't behave well. Avoid this by increasing the context number to 64bits. This way even when userspace manages to allocate a billion contexts per second it takes more than 500 years for the context number to wrap around. v2: fix printf formats as well.
