Meta: Add license header to source files 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. 2020-01-18 09:38:21 +01:00			`/*`

Everything: Move to SPDX license identifiers in all files. 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 * 2021-04-22 01:24:48 -07:00			`* SPDX-License-Identifier: BSD-2-Clause`

Kernel: Qualify a bunch of #include statements. 2019-06-07 19:29:34 +02:00			`#include <Kernel/CMOS.h>`
Kernel: Absorb LibBareMetal back into the kernel This was supposed to be the foundation for some kind of pre-kernel environment, but nobody is working on it right now, so let's move everything back into the kernel and remove all the confusion. 2020-05-16 12:00:04 +02:00			`#include <Kernel/IO.h>`
Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work. 2018-10-16 11:01:38 +02:00

AK: Rename the common integer typedefs to make it obvious what they are. These types can be picked up by including <AK/Types.h>: * u8, u16, u32, u64 (unsigned) * i8, i16, i32, i64 (signed) 2019-07-03 21:17:35 +02:00			`u8 read(u8 index)`
