2021-08-06	Kernel: Rename Process::space() => Process::address_space()	Andreas Kling
	We commonly talk about "a process's address space" so let's nudge the code towards matching how we talk about it. :^)
2021-08-06	Kernel: Rename Range => VirtualRange	Andreas Kling
	...and also RangeAllocator => VirtualRangeAllocator. This clarifies that the ranges we're dealing with are virtual memory ranges and not anything else.
2021-08-06	Kernel: Move Kernel/Memory/ code into Kernel::Memory namespace	Andreas Kling

2021-08-06	Kernel: Rename Kernel/VM/ to Kernel/Memory/	Andreas Kling
	This directory isn't just about virtual memory, it's about all kinds of memory management.
2021-04-22	Everything: Move to SPDX license identifiers in all files.	Brian Gianforcaro
	SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
2021-03-19	Kernel: Refactor storage stack with u64 as mmap offset	Jean-Baptiste Boric

2021-02-08	Kernel: Factor address space management out of the Process class	Andreas Kling
	This patch adds Space, a class representing a process's address space. - Each Process has a Space. - The Space owns the PageDirectory and all Regions in the Process. This allows us to reorganize sys$execve() so that it constructs and populates a new Space fully before committing to it. Previously, we would construct the new address space while still running in the old one, and encountering an error meant we had to do tedious and error-prone rollback. Those problems are now gone, replaced by what's hopefully a set of much smaller problems and missing cleanups. :^)
2021-01-25	Kernel: Hoist VM range allocation up to sys$mmap() itself	Andreas Kling
	Instead of letting each File subclass do range allocation in their mmap() override, do it up front in sys$mmap(). This makes us honor alignment requests for file-backed memory mappings and simplifies the code somwhat.
2021-01-20	Kernel+LibC: Turn errno codes into a strongly typed enum	Andreas Kling
	..and allow implicit creation of KResult and KResultOr from ErrnoCode. This means that kernel functions that return those types can finally do "return EINVAL;" and it will just work. There's a handful of functions that still deal with signed integers that should be converted to return KResults.
2021-01-15	Kernel: Make Process::allocate_region() return KResultOr<Region>	Andreas Kling
	This allows region allocation to return specific errors and we don't have to assume every failure is an ENOMEM.
2021-01-15	Kernel: Add anonymous files, created with sys$anon_create()	Andreas Kling
	This patch adds a new AnonymousFile class which is a File backed by an AnonymousVMObject that can only be mmap'ed and nothing else, really. I'm hoping that this can become a replacement for shbufs. :^)
