Merge branch 'drm-next-5.3' of git://people.freedesktop.org/~agd5f/linux into drm-next
New stuff for 5.3: - Add new thermal sensors for vega asics - Various RAS fixes - Add sysfs interface for memory interface utilization - Use HMM rather than mmu notifier for user pages - Expose xgmi topology via kfd - SR-IOV fixes - Fixes for manual driver reload - Add unique identifier for vega asics - Clean up user fence handling with UVD/VCE/VCN blocks - Convert DC to use core bpc attribute rather than a custom one - Add GWS support for KFD - Vega powerplay improvements - Add CRC support for DCE 12 - SR-IOV support for new security policy - Various cleanups From: Alex Deucher <alexdeucher@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190529220944.14464-1-alexander.deucher@amd.com
