2022-02-09	Kernel: Change static constexpr variables to constexpr where possible	Lenny Maiorani
	Function-local `static constexpr` variables can be `constexpr`. This can reduce memory consumption, binary size, and offer additional compiler optimizations. These changes result in a stripped x86_64 kernel binary size reduction of 592 bytes.
2022-01-21	Kernel: Replace {String => KString}::formatted in ACPISysFSDirectory	Idan Horowitz

2022-01-21	Kernel: Make ACPI reboot OOM-fallible	Idan Horowitz

2022-01-18	Kernel: Don't populate the ACPI SysFS directory with a disabled ACPI	Idan Horowitz
	This would cause a nullptr dereference on ACPI::Parser::the().
2022-01-13	Kernel: Make map_typed() & map_typed_writable() fallible using ErrorOr	Idan Horowitz
	This mostly just moved the problem, as a lot of the callers are not capable of propagating the errors themselves, but it's a step in the right direction.
2022-01-13	Kernel: Make map_bios() and map_ebda() fallible using ErrorOr	Idan Horowitz

2022-01-07	Everywhere: Fix many spelling errors	mjz19910

2022-01-05	Kernel: Use MUST + Vector::try_empend instead of Vector::empend	Brian Gianforcaro
	In preparation for making Vector::empend unavailable during compilation of the Kernel.
2022-01-05	Kernel: Use MUST + Vector::try_append instead of Vector::append	Brian Gianforcaro
	In preparation for making Vector::append unavailable during compilation of the Kernel.
2022-01-04	Kernel: Scan ACPI memory ranges for the RSDP table	Tom
	On some systems the ACPI RSDP table may be located in ACPI reserved memory ranges rather than in the EBDA or BIOS areas.
2022-01-04	Kernel: Fix determining EBDA size	Tom
	The first byte of the EBDA structure contains the size of the EBDA in 1 KiB units. We were incorrectly using the word at offset 0x413 of the BDA which specifies the number of KiB before the EBDA structure.
2021-12-28	Kernel: Propagate overflow errors from Memory::page_round_up	Guilherme Goncalves
	Fixes #11402.
2021-12-23	Kernel: Move Multi Processor Parser code to a separate directory	Liav A

2021-12-14	Kernel/SysFS: Don't allocate ACPISysFS components in constructors	Liav A
	Instead defer it to a method to be called after the construction of ACPISysFSDirectory.
2021-12-14	Kernel/SysFS: Make it clear that some components must be created in boot	Liav A
	Using the phrase "create" doesn't give information on whether the object must be allocated or a failure to do so can be handled gracefully. Therefore, we must use better phrase for such purpose, so "must_create" for the allocate-and-construct static methods is definitely good choice.
2021-12-14	Kernel/SysFS: Prevent allocation for component name during construction	Liav A
	Instead, allocate before constructing the object and pass NonnullOwnPtr of KString to the object if needed. Some classes can determine their names as they have a known attribute to look for or have a static name.
2021-12-11	Everywhere: Fix -Winconsistent-missing-override warnings from Clang	Daniel Bertalan
	This option is already enabled when building Lagom, so let's enable it for the main build too. We will no longer be surprised by Lagom Clang CI builds failing while everything compiles locally. Furthermore, the stronger `-Wsuggest-override` warning is enabled in this commit, which enforces the use of the `override` keyword in all classes, not just those which already have some methods marked as `override`. This works with both GCC and Clang.
2021-12-09	Kernel: Mark ACPI::Parser's empty destructor as default	Hendiadyoin1

2021-11-11	Everywhere: Pass AK::StringView by value	Andreas Kling

2021-11-10	AK+Everywhere: Stop including Vector.h from StringView.h	Andreas Kling
	Preparation for using Error.h from Vector.h. This required moving some things out of line.
2021-11-08	Kernel: Replace KResult and KResultOr<T> with Error and ErrorOr<T>	Andreas Kling
	We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace! This was a slightly tedious refactoring that took a long time, so it's not unlikely that some bugs crept in. Nevertheless, it does pass basic functionality testing, and it's just real nice to finally see the same pattern in all contexts. :^)
2021-11-02	Kernel: Switch BIOSSysFSComponent constructor to AK::StringView	Brian Gianforcaro
	These are constants, they don't need to be dynamically allocated. Another minor step towards removing `AK::String` from the Kernel and improving OOM safety.
2021-10-09	Kernel/SysFS: Provide a way to "truncate" and "set" mtime on inodes	Liav A
	Normally, trying to truncate a SysFSInode should result in EPERM error. However, as suggested by Ali (@alimpfard), we can allow the PowerState node to be "truncated" so one can open that file with O_TRUNC option. Likewise, we also need to provide a way to set modified time on SysFS inodes. For most inodes, we should return ENOTIMPL error, but for the power state switch, we ignore the modified time setting and just return KSuccess. These fixes allow to do "echo -n 1 > /sys/firmware/power_state" in Shell after gaining root permissions, to switch the power state.
2021-10-03	Kernel: Use `operator ""sv` in all purpose() implementations	Brian Gianforcaro
	Previously there was a mix of returning plain strings and returning explicit string views using `operator ""sv`. This change switches them all to standardized on `operator ""sv` as it avoids a call to strlen.
2021-10-01	Kernel: Move x86 IO instructions code into the x86 specific folder	Liav A

2021-09-12	Kernel+Userland: Introduce a new way to reboot and poweroff the machine	Liav A
	This change removes the halt and reboot syscalls, and create a new mechanism to change the power state of the machine. Instead of how power state was changed until now, put a SysFS node as writable only for the superuser, that with a defined value, can result in either reboot or poweroff. In the future, a power group can be assigned to this node (which will be the GroupID responsible for power management). This opens an opportunity to permit to shutdown/reboot without superuser permissions, so in the future, a userspace daemon can take control of this node to perform power management operations without superuser permissions, if we enforce different UserID/GroupID on that node.
2021-09-12	Kernel: Unify BIOS and ACPI components in the SysFS firmware directory	Liav A
	Both should reside in the SysFS firmware directory which is normally located in /sys/firmware. Also, apply some OOM-safety patterns when creating the BIOS and ACPI directories.
2021-09-12	Kernel: Move ACPI and BIOS code into the new Firmware directory	Liav A
	This will somwhat help unify them also under the same SysFS directory in the commit. Also, it feels much more like this change reflects the reality that both ACPI and the BIOS are part of the firmware on x86 computers.
