Changes in v5:
  * Changed the subject line of this cover letter to not use the old
    DeviceSize name.

  * Collected Reviewed-by tags from Alexandre Courbot and Joel
    Fernandes, and Acked-by from Gary Guo.

  * Added a new patch 3/3 with a todo.rst entry for device address
    type wrappers and a marker trait, as discussed with Danilo.

  * Rebased onto latest drm-rust-next.

Changes in v4:
  * Renamed the trait from DeviceSize to SizeConstants.

  * Added backticks and trailing periods to all hex-value doc comments
    on the SZ_* constants.

  * Removed redundant type annotations from doc-test examples.

  * Used a `use` import for PAGE_SIZE in the module-level doc-test
    instead of a fully qualified path.

  * Rewrote doc-test comments to clarify the distinction between
    module-level constants (no type qualifier) and trait associated
    constants (type qualifier required).

  * Added Reviewed-by from Eliot Courtney.

Changes in v3:
  * Dropped the Alignment::from_u64() patch.

  * Reworked define_sizes! macro to accept target types as arguments
    (define_sizes!(u32, u64, usize)) using recursive macro arms,
    instead of hardcoding impls for u32 and u64. Overflow checking
    uses u128 casts so the same assert works for any ("reasonable")
    target type.

  * Added usize to the DeviceSize implementations, so the trait
    covers u32, u64, and usize.

  * Hex values for each constant are now proper doc-comments
    (forwarded via macro meta), instead of inline comments.

  * Rebased onto latest drm-rust-next.

Changes in v2:
  * Replaced flat SZ_*_U64 constants with a DeviceSize trait that
    provides SZ_* as associated constants on u32 and u64.

  * A define_sizes! macro generates everything from one list of names.

  * Added Alignment::from_u64() so alignment values can be constructed
    from DeviceSize constants without falling back to usize variants.

  * Rebased onto drm-rust-next. No longer depends on the Blackwell
    patchset.
