RootTable, Mapping, IdMap and LinearMap are now correctly marked as Send, as it doesn't matter where they are used from.bitflags to 2.0.2, which changes the API of Attributes a bit.map_range method to support mapping leaf page table entries without the VALID flag. Attributes::VALID is no longer implicitly set when mapping leaf page table entries.modify_range method to IdMap, LinearMap and Mapping to update details of a mapped range. This can be used e.g. to change flags for some range which is already mapped. As part of this, the Descriptor struct was added to the public API.DBM and software flags to Attributes.Translation trait responsible for allocating page tables. This should help make it possible to use more complex mapping schemes, and to construct page tables in a different context to where they are used.AddressRangeError to MapError, which is now an enum with three variants and implements Display.From<*const T> and From<*mut T> are no longer implemented for VirtualAddress.alloc dependency optional via a feature flag.LinearMap.Debug and Display for MemoryRegion.From<Range<VirtualAddress>> for MemoryRegion.PhysicalAddress and VirtualAddress.IdMap::map_range; it will now return an error if you attempt to map a virtual address outside the range of the page table given its configured root level.Debug for PhysicalAddress and VirtualAddress.Display and Drop implementation for RootTable that would result in a crash for any pagetable with non-zero mappings.Display implementation for PhysicalAddress and VirtualAddress to use correct number of digits.Initial release.
