2021-04-23	AK: Rename adopt() to adopt_ref()	Andreas Kling
	This makes it more symmetrical with adopt_own() (which is used to create a NonnullOwnPtr from the result of a naked new.)
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 *
2021-02-23	Everywhere: Rename ASSERT => VERIFY	Andreas Kling
	(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED) Since all of these checks are done in release builds as well, let's rename them to VERIFY to prevent confusion, as everyone is used to assertions being compiled out in release. We can introduce a new ASSERT macro that is specifically for debug checks, but I'm doing this wholesale conversion first since we've accumulated thousands of these already, and it's not immediately obvious which ones are suitable for ASSERT.
2021-02-11	Kernel: Remove a handful of unused things in VM/ directory	Andreas Kling
	Also add some missing initializers.
2021-02-08	Everywhere: Replace dbgln<flag>(...) with dbgln_if(flag, ...)	AnotherTest
	Replacement made by `find Kernel Userland -name '.h' -o -name '.cpp' \| sed -i -Ee 's/dbgln\b<(\w+)>\(/dbgln_if(\1, /g'`
2021-01-28	Kernel: Allow specifying a physical alignment when allocating	Tom
	Some drivers may require allocating contiguous physical pages with a specific alignment for the physical address.
2021-01-25	Everywhere: Debug macros instead of constexpr.	asynts
	This was done with the following script: find . \( -name '.cpp' -o -name '.h' -o -name '.in' \) -not -path './Toolchain/' -not -path './Build/' -exec sed -i -E 's/dbgln<debug_([a-z_]+)>/dbgln<\U\1_DEBUG>/' {} \; find . \( -name '.cpp' -o -name '.h' -o -name '.in' \) -not -path './Toolchain/' -not -path './Build/' -exec sed -i -E 's/if constexpr \(debug_([a-z0-9_]+)/if constexpr \(\U\1_DEBUG/' {} \;
2021-01-22	Everywhere: Replace a bundle of dbg with dbgln.	asynts
	These changes are arbitrarily divided into multiple commits to make it easier to find potentially introduced bugs with git bisect.
2021-01-01	Kernel: Implement lazy committed page allocation	Tom
	By designating a committed page pool we can guarantee to have physical pages available for lazy allocation in mappings. However, when forking we will overcommit. The assumption is that worst-case it's better for the fork to die due to insufficient physical memory on COW access than the parent that created the region. If a fork wants to ensure that all memory is available (trigger a commit) then it can use madvise. This also means that fork now can gracefully fail if we don't have enough physical pages available.
2020-03-08	Kernel: Allow contiguous allocations in physical memory	Liav A
	For that, we have a new type of VMObject, called ContiguousVMObject, that is responsible for allocating contiguous physical pages.
