2020-08-25	Kernel: Switch singletons to use new Singleton class	Tom
	MemoryManager cannot use the Singleton class because MemoryManager::initialize is called before the global constructors are run. That caused the Singleton to be re-initialized, causing it to create another MemoryManager instance. Fixes #3226
2020-08-22	Revert "Kernel: Switch singletons to use new Singleton class"	Andreas Kling
	This reverts commit f48feae0b2a300992479abf0b2ded85e45ac6045.
2020-08-22	Revert "Kernel: Move Singleton class to AK"	Andreas Kling
	This reverts commit f0906250a181c831508a45434b9f645ff98f33e4.
2020-08-22	Revert "AK: Get rid of make_singleton function"	Andreas Kling
	This reverts commit 5a98e329d157a2db8379e0c97c6bdc1328027843.
2020-08-22	AK: Get rid of make_singleton function	Tom
	Just default the InitFunction template argument.
2020-08-22	Kernel: Move Singleton class to AK	Tom

2020-08-21	Kernel: Switch singletons to use new Singleton class	Tom
	Fixes #3226
2020-07-06	Kernel: Require a reason to be passed to Thread::wait_on	Tom
	The Lock class still permits no reason, but for everything else require a reason to be passed to Thread::wait_on. This makes it easier to diagnose why a Thread is in Queued state.
2020-07-03	Kernel: Consolidate features into CPUFeature enum	Tom
	This allows us to consolidate printing out all the CPU features into one log statement. Also expose them in /proc/cpuinfo
2020-07-01	Kernel: Turn Thread::current and Process::current into functions	Tom
	This allows us to query the current thread and process on a per processor basis
2020-06-27	Kernel: Make Random work on CPUs without rdrand	Peter Elliott
	- If rdseed is not available, fallback to rdrand. - If rdrand is not available, block for entropy, or use insecure prng depending on if user wants fast or good random.
2020-06-27	Kernel: Add g_cpu_supports_rdseed	3541
	CPUs which support RDRAND do not necessarily support RDSEED. This introduces a flag g_cpu_supports_rdseed which is set appropriately by CPUID. This causes Haswell CPUs in particular (and probably a lot of AMD chips) to now fail to boot with #2634, rather than an illegal instruction. It seems like the KernelRng needs either an initial reseed call or more random events added before the first call to get_good_random, but I don't feel qualified to make that kind of change.
2020-06-25	Kernel: Harvest randomness from various drivers	Peter Elliott
	Random now gets entropy from the following drivers: - KeyboardDevice - PATAChannel - PS2MouseDevice - E1000NetworkAdapter - RTL8139NetworkAdapter Of these devices, PS2MouseDevice and PATAChannel provide the vast majority of the entropy.
2020-06-25	Kernel: Replace existing random implementation with Fortuna	Peter Elliott

2020-05-20	Kernel: Fix invalid jump in case RDRAND fails	Andreas Kling
	If RDRAND doesn't give us data, we want to try again, not jump to some low address like 0x80 :^)
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.
2020-01-03	Kernel: Add a more expressive API for getting random bytes	Andreas Kling
	We now have these API's in <Kernel/Random.h>: - get_fast_random_bytes(u8* buffer, size_t buffer_size) - get_good_random_bytes(u8* buffer, size_t buffer_size) - get_fast_random<T>() - get_good_random<T>() Internally they both use x86 RDRAND if available, otherwise they fall back to the same LCG we had in RandomDevice all along. The main purpose of this patch is to give kernel code a way to better express its needs for random data. Randomness is something that will require a lot more work, but this is hopefully a step in the right direction.
