This series attempts to promote helpers used by Xe [1] to libfs.
Earlier attempt [2] with similar helper was unnoticed.

[1] https://patchwork.freedesktop.org/series/140848/#rev1
[2] https://patchwork.freedesktop.org/series/133507/#rev1

v1: https://patchwork.freedesktop.org/series/141060/#rev1
v2: use iterate_and_advance to treat user_iter separately (Matthew)

Michal Wajdeczko (4):
  iov_iter: Provide copy_iomem_to|from_iter()
  libfs: Provide simple_read_from|write_to_iomem()
  drm/xe: Add read/write debugfs helpers for GGTT node
  drm/xe/pf: Expose access to the VF GGTT PTEs over debugfs
