[PATCH v2] drm/xe: Carve out wopcm portion from the stolen memory

by Nirmoy Das

The top of stolen memory is WOPCM, which shouldn't be accessed. Remove this portion from the stolen memory region for discrete platforms. This was already done for integrated, but was missing for discrete platforms. This also moves get_wopcm_size() so detect_bar2_dgfx() and detect_bar2_integrated can use the same function. v2: Improve commit message and suitable stable version tag(Lucas) Fixes: d8b52a02cb40 ("drm/xe: Implement stolen memory.")

[PATCH 2/3] maple_tree: restart walk on correct status

by Wei Yang

Commit a8091f039c1e ("maple_tree: add MAS_UNDERFLOW and MAS_OVERFLOW states") adds more status during maple tree walk. But it introduce a typo on the status check during walk. It expects to mean neither active nor start, we would restart the walk, while current code means we would always restart the walk.

Retrying I/Os during "depopulation in progress" or "depopulation restore in progress" results in a continuous retry loop until the depopulation completes or until the I/O retry loop is aborted due to a timeout by the scsi_cmd_runtime_exceeced(). Depopulation is slow and can take 24+ hours to complete on 20+ TB HDDs. Most I/Os in the depopulation retry loop end up taking several minutes before returning the failure to user space.
