Move kernel symbolication code out of init.cpp and into its own KSym files. Also use a simple array of { dword, const char* } for the KSyms and put the whole shebang in kmalloc_eternal() memory. This was a fugly source of kmalloc perma-frag. 2018-12-25 00:59:10 +03:00			`#pragma once`

AK: Rename <AK/AKString.h> to <AK/String.h> This was a workaround to be able to build on case-insensitive file systems where it might get confused about <string.h> vs <String.h>. Let's just not support building that way, so String.h can have an objectively nicer name. :^) 2019-09-06 16:34:26 +03:00			`#include <AK/String.h>`

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 22:17:35 +03:00			`u32 address;`

Kernel: Allow modules to link against anything in kernel.map :^) We now use the symbols from kernel.map to link modules as they are loaded into the kernel. This is pretty fricken cool! 2019-11-28 23:30:20 +03:00			`u32 address_for_kernel_symbol(const char* name);`

Kernel: Make dump_backtrace() kinda sorta work. 2019-02-24 16:51:48 +03:00
Kernel: Simplify dump_backtrace() API for clients. It makes no sense that clients had to worry about whether or not KSyms were loaded. 2019-05-16 14:41:16 +03:00			`void dump_backtrace();`
