[PATCH 02/13] amdgpu: don't initialize range->list in amdgpu_hmm_init_range
...I've seen code that uses list_empty to check whether a list head has
been added to a list or not. For that to work, the list head needs to be
initialized, and it has to be removed with list_del_init. If HMM doesn't
ever do that with range->list, then this patch is Reviewed-by: Felix

[PATCH hmm v2 1/5] mm/hmm: make CONFIG_DEVICE_PRIVATE into a select
...ould
be selected by drivers that are going to use the feature, similar to how
CONFIG_HMM_MIRROR works.
Currently all drivers provide a feature kconfig that will disable use of
DEVICE_PRIVATE in that driver, allowing users to avoid enabling this if
they don't want the overhead.

[PATCH hmm v2 4/5] mm/hmm: remove HMM_PFN_SPECIAL

This is just an alias for HMM_PFN_ERROR, nothing cares that the error was
because of a special page vs any other error case.
