Is coarse-grained buffer SVM a required OpenCL 3.0 feature?

[pjaaskel]

There are conflicting sentences related to this feature:

On page 35 (3.3.3) of https://registry.khronos.org/OpenCL/specs/3.0-unified/pdf/OpenCL_API.pdf it says:

Coarse-Grained buffer SVM is required in the core OpenCL specification. The two finer grained approaches are optional features in OpenCL.

While on page 80 (CL_DEVICE_SVM_CAPABILITIES query) it says:

The mandated minimum capability for an OpenCL 2.0, 2.1, or 2.2 device is CL_DEVICE_SVM_COARSE_GRAIN_BUFFER. For other device versions there is no mandated minimum capability.

SVM is not required for OpenCL 3.0. This is a bug and the sentence cited above on page 35 should be updated (I thought I got all of these but apparently I missed one!). I'll fix this.
