[PATCH i-g-t v7 00/10] Madvise feature in SVM for Multi-GPU configs

[nishit.sharma@intel.com]

From: Nishit Sharma <nishit.sharma@intel.com>

This patch series adds comprehensive SVM multi-GPU IGT test coverage for
madvise and prefetch functionality.

ver2:
- Test name changed in commits
- In patchwork v1 patch is missing due to last patch was not sent

ver3:
- In patch-7 tags were added and it was not sent on patchwork

ver4:
- In patch file was added which is not available in source which caused
  CI build failure.

ver5:
- Added subtest function wrappers
- Subtests executing for all GPUs enumerated

ver7:
- Optimized function calling which are frequenctly called
- Incorporated review comments (Thomas Hellstrom)
