dma-direct: rename and cleanup __phys_to_dma

2020-09-11T07:14:43Z

The __phys_to_dma vs phys_to_dma distinction isn't exactly obvious. Try to improve the situation by renaming __phys_to_dma to phys_to_dma_unencryped, and not forcing architectures that want to override phys_to_dma to actually provide __phys_to_dma.

MIPS: Retire kvm paravirt

2020-07-24T08:53:23Z

paravirt machine was introduced for Cavium's partial virtualization technology, however, it's host side support and QEMU support never landed in upstream. As Cavium was acquired by Marvel and they have no intention to maintain their MIPS product line, also paravirt is unlikely to be utilized by community users, it's time to retire it if nobody steps in to maintain it.

irqdomain/treewide: Free firmware node after domain removal

2020-07-22T22:08:52Z

Commit 711419e504eb ("irqdomain: Add the missing assignment of domain->fwnode for named fwnode") unintentionally caused a dangling pointer page fault issue on firmware nodes that were freed after IRQ domain allocation. Commit e3beca48a45b fixed that dangling pointer issue by only freeing the firmware node after an IRQ domain allocation failure. That fix no longer frees the firmware node immediately, but leaves the firmware node allocated after the domain is removed. The firmware node must be kept around through irq_domain_remove, but should be freed it afterwards. Add the missing free operations after domain removal where where appropriate.

irqdomain/treewide: Keep firmware node unconditionally allocated

2020-07-14T15:44:42Z

Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after creating the irqdomain. The only purpose of these FW nodes is to convey name information. When this was introduced the core code did not store the pointer to the node in the irqdomain. A recent change stored the firmware node pointer in irqdomain for other reasons and missed to notice that the usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence are broken by this. Storing a dangling pointer is dangerous itself, but in case that the domain is destroyed later on this leads to a double free. Remove the freeing of the firmware node after creating the irqdomain from all affected call sites to cure this.
