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			`#pragma once`

Share code between spawn() and exec() implementations. Okay, now there's only one ELF loading client in the process launch code. 2018-11-03 10:49:13 +01:00			`#include <AK/Types.h>`

Use modern C++ attributes instead of __attribute__ voodoo. This is quite nice, although I wish [[gnu::always_inline]] implied inline. Also "gnu::" is kind of a wart, but whatcha gonna do. 2019-02-15 12:30:48 +01:00			`struct [[gnu::packed]] TSS32 {`
