This v8 series enables Transparent Huge Page (THP) support in `drm_pagemap` for GPU device memory migration, targeting significant performance improvements for SVM (Shared Virtual Memory) workloads on Intel Xe GPUs. The series is well-structured as incremental refactoring (patches 1-3) followed by the feature enablement (patch 4). The core approach — converting page-level operations to folio-level and adding `MIGRATE_VMA_SELECT_COMPOUND` — is sound.
The series has good review coverage (Reviewed-by from Matthew Brost and Balbir Singh). A few issues are noted below, most notably a potential `VM_WARN` with device-coherent pages in patch 2, and a return type mismatch in patch 3.
