2021-02-14	Kernel: Assert if rounding-up-to-page-size would wrap around to 0	Andreas Kling
	If we try to align a number above 0xfffff000 to the next multiple of the page size (4 KiB), it would wrap around to 0. This is most likely never what we want, so let's assert if that happens.
2021-02-09	Kernel: Convert all *Builder::appendf() => appendff()	Andreas Kling

2021-01-03	Kernel: Improve ProcFS behavior in low memory conditions	Tom
	When ProcFS could no longer allocate KBuffer objects to serve calls to read, it would just return 0, indicating EOF. This then triggered parsing errors because code assumed it read the file. Because read isn't supposed to return ENOMEM, change ProcFS to populate the file data upon file open or seek to the beginning. This also means that calls to open can now return ENOMEM if needed. This allows the caller to either be able to successfully open the file and read it, or fail to open it in the first place.
2021-01-01	Kernel: Merge PurgeableVMObject into AnonymousVMObject	Tom
	This implements memory commitments and lazy-allocation of committed memory.
2020-12-18	Kernel: Move KBufferBuilder to the fallible KBuffer API	Andreas Kling
	KBufferBuilder::build() now returns an OwnPtr<KBuffer> and can fail. Clients of the API have been updated to handle that situation.
2020-11-02	AK+Kernel: Escape JSON keys & values	Andreas Kling
	Grab the escaping logic from JSON string value serialization and use it for serializing all keys and values. Fixes #3917.
2020-08-16	AK: Rename KB, MB, GB to KiB, MiB, GiB	Nico Weber
	The SI prefixes "k", "M", "G" mean "10^3", "10^6", "10^9". The IEC prefixes "Ki", "Mi", "Gi" mean "2^10", "2^20", "2^30". Let's use the correct name, at least in code. Only changes the name of the constants, no other behavior change.
2020-07-05	Kernel: Fix KBufferBuilder::append()	Sergey Bugaev
	insertion_ptr() already includes the offset.
2020-05-14	Build: Switch to CMake :^)	Sergey Bugaev
	Closes https://github.com/SerenityOS/serenity/issues/2080
2020-02-16	Kernel: Move all code into the Kernel namespace	Andreas Kling

2020-01-18	Meta: Add license header to source files	Andreas Kling
	As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.
2019-12-25	Kernel: Make kernel memory regions be non-executable by default	Andreas Kling
	From now on, you'll have to request executable memory specifically if you want some.
2019-12-12	Kernel: Bump KBufferBuilder VM allocation to 4 MB	Andreas Kling
	This is pretty large but since it's not eagerly committed to physical pages, it's probably okay. I'm bumping this after running out of space for a ProtocolServer profile run :^)
2019-08-06	Kernel: Add KBufferBuilder, similar to StringBuilder but for KBuffer	Andreas Kling
	This class works by eagerly allocating 1MB of virtual memory but only adding physical pages on demand. In other words, when you append to it, its memory usage will increase by 1 page whenever you append across a page boundary (4KB.)
