2021-07-26iommu/vt-d: Report real pgsize bitmap to iommu coreLu Baolu
The pgsize bitmap is used to advertise the page sizes our hardware supports to the IOMMU core, which will then use this information to split physically contiguous memory regions it is mapping into page sizes that we support. Traditionally the IOMMU core just handed us the mappings directly, after making sure the size is an order of a 4KiB page and that the mapping has natural alignment. To retain this behavior, we currently advertise that we support all page sizes that are an order of 4KiB. We are about to utilize the new IOMMU map/unmap_pages APIs. We could change this to advertise the real page sizes we support.

2021-07-26iommu: Streamline iommu_iova_to_phys()Robin Murphy
If people are going to insist on calling iommu_iova_to_phys() pointlessly and expecting it to work, we can at least do ourselves a favour by handling those cases in the core code, rather than repeatedly across an inconsistent handful of drivers. Since all the existing drivers implement the internal callback, and any future ones are likely to want to work with iommu-dma which relies on iova_to_phys a fair bit, we may as well remove that currently-redundant check as well and consider it mandatory.

2021-07-26iommu: Print strict or lazy mode at init timeJohn Garry
As well as the default domain type, it's useful to know whether strict or lazy for DMA domains, so add this info in a separate print. The (stict/lazy) mode may be also set via iommu.strict earlyparm, but this will be processed prior to iommu_subsys_init(), so that print will be accurate for drivers which don't set the mode via custom means. For the drivers which set the mode via custom means - AMD and Intel drivers - they maintain prints to inform a change in policy or that custom cmdline methods to change policy are deprecated.

2021-07-22dpaa2-switch: seed the buffer pool after allocating the swpIoana Ciornei
Any interraction with the buffer pool (seeding a buffer, acquire one) is made through a software portal (SWP, a DPIO object). There are circumstances where the dpaa2-switch driver probes on a DPSW before any DPIO devices have been probed. In this case, seeding of the buffer pool will lead to a panic since no SWPs are initialized. To fix this, seed the buffer pool after making sure that the software portals have been probed and are ready to be used.
