HMM callers use PFN list to populate range while calling
to hmm_range_fault(), the conversion from PFN to DMA address
is done by the callers with help of another DMA list. However,
it is wasteful on any modern platform and by doing the right
logic, that DMA list can be avoided.
Provide generic logic to manage these lists and gave an interface
to map/unmap PFNs to DMA addresses, without requiring from the callers
to be an experts in DMA core API.

Currently the only efficient way to map a complex memory description through
the DMA API is by using the scatter list APIs. The SG APIs are unique in that
they efficiently combine the two fundamental operations of sizing and allocating
a large IOVA window from the IOMMU and processing all the per-address
swiotlb/flushing/p2p/map details.
This uniqueness has been a long standing pain point as the scatter list API
is mandatory, but expensive to use. It prevents any kind of optimization or
feature improvement (such as avoiding struct page for P2P) due to the
impossibility of improving the scatter list.
Several approaches have been explored to expand the DMA API with additional
scatterlist-like structures (BIO, rlist), instead split up the DMA API
to allow callers to bring their own data structure.
The API is split up into parts:
- Allocate IOVA space:
To do any pre-allocation required. This is done based on the caller
supplying some details about how much IOMMU address space it would need
in worst case.
- Map and unmap relevant structures to pre-allocated IOVA space:
Perform the actual mapping into the pre-allocated IOVA. This is very
similar to dma_map_page().

The existing .map_pages() callback provides both allocating of IOVA
and linking DMA pages. That combination works great for most of the
callers who use it in control paths, but is less effective in fast
paths where there may be multiple calls to map_page().
These advanced callers already manage their data in some sort of
database and can perform IOVA allocation in advance, leaving range
linkage operation to be in fast path.
Provide an interface to allocate/deallocate IOVA and next patch
link/unlink DMA ranges to that specific IOVA.
In the new API a DMA mapping transaction is identified by a
struct dma_iova_state, which holds some recomputed information
for the transaction which does not change for each page being
mapped, so add a check if IOVA can be used for the specific
transaction.
The API is exported from dma-iommu as it is the only implementation
supported, the namespace is clearly different from iommu_* functions
which are not allowed to be used. This code layout allows us to save
function call per API call used in datapath as well as a lot of boilerplate
code.

Formalize __iommu_map() into iommu_map_nosync() which requires the

- net: fix geneve_opt length integer overflow
- udp: fix multiple wrap arounds of sk->sk_rmem_alloc when it
approaches INT_MAX
- dsa: mvpp2: add a lock to avoid corruption of the shared TCAM

devmem code performs a number of safety checks to avoid having
to reimplement all of them in the drivers. Move those to
__net_mp_open_rxq() and reuse that function for binding to make
sure that io_uring ZC also benefits from them.
While at it rename the queue ID variable to rxq_idx in
__net_mp_open_rxq(), we touch most of the relevant lines.
The XArray insertion is reordered after the netdev_rx_queue_restart()
call, otherwise we'd need to duplicate the queue index check
or risk inserting an invalid pointer. The XArray allocation
failures should be extremely rare.

The ublk bits could've gone via either tree - usually I put them in

supported that ended up dipping into both trees.
This contains:
- Fix for sendmsg zc, include in pinned pages accounting like we do
for the other zc types
- Series for ublk fixing request aborting, doing various little
cleanups, fixing some zc issues, and adding queue_rqs support
- Another ublk series doing some code cleanups
- Series cleaning up the io_uring send path, mostly in preparation
for registered buffers
- Series doing little MSG_RING cleanups
- Fix for the newly added zc rx, fixing len being 0 for the last
invocation of the callback
- Add vectored registered buffer support for ublk. With that, then
ublk also supports this feature in the kernel revision where it
could generically introduced for rw/net
- A bunch of selftest additions for ublk. This is the majority of the
diffstat
