[PATCH 0/8] dma::Coherent & dma::CoherentInit API

[Danilo Krummrich <dakr@kernel.org>]

This patch series introduces the dma::Coherent API Gary worked out in the
context of his I/O projection work.

Additionally, introduce dma::CoherentInit, a type that encapsulates a
dma::Coherent object before its DMA address is exposed to the device.
dma::CoherentInit can guarantee exclusive access to the inner dma::Coherent
object and implement Deref and DerefMut.

Also add Coherent::init() and Coherent::init_with_attrs() so we can directly
initialize a new dma::Coherent object through an impl Init<T, E>.

Danilo Krummrich (5):
  rust: dma: use "kernel vertical" style for imports
  rust: dma: introduce dma::CoherentInit for memory initialization
  rust: dma: add Coherent:init() and Coherent::init_with_attrs()
  gpu: nova-core: use Coherent::init to initialize GspFwWprMeta
  gpu: nova-core: convert Gsp::new() to use CoherentInit

Gary Guo (3):
  rust: dma: add generalized container for types other than slices
  rust: dma: add zeroed constructor to `Coherent`
  gpu: nova-core: convert to new dma::Coherent API
