2021-07-20	per-process virtual memory	dzwdz
	VGA is only mapped into the virtual memory because there are no other ways of interacting with the OS.
2021-07-20	rename pagedir_use() to pagedir_switch()	dzwdz
	imo "use" was slightly misleading
2021-07-20	only enable paging when jumping into ring 0	dzwdz
	The kernel can't use the limited paging tables of user processes. Alternatively, sysenter could accept a parameter with a new cr3. That would allow/require using paging in the kernel - so I'll switch to it later, but I want to get other stuff done first.
2021-07-20	global PAGE_MASK define	dzwdz
	it's pretty useful, so it makes sense to define it alongside PAGE_SIZE
2021-07-19	fix some style inconsistenties	dzwdz

2021-07-19	remove the unused r3_test function	dzwdz

2021-07-19	very basic paging	dzwdz

2021-07-19	add a page fault handler	dzwdz

2021-07-18	basic executable loading	dzwdz

2021-07-18	clean up the linker script, remove duplicate labels	dzwdz

2021-07-18	fix most current compiler warnings	dzwdz
	stack_top got changed into a char, because `extern void` isn't even valid. others are self-explanatory
2021-07-18	move the kernel linker script to src/kernel/	dzwdz

2021-07-18	move all kernel sources to src/kernel/	dzwdz

2021-07-17	detect the highest used memory address, and only allocate pages above it	dzwdz

2021-07-17	Revert "debug code, verifies if the memory gets set up correctly"	dzwdz
	not meant to be in the main tree, included for completeness
2021-07-17	debug code, verifies if the memory gets set up correctly	dzwdz
	i guess that i can include this for completeness. if not for the awful pointer printing thingy this could probably get into the main version. TODO?
2021-07-17	basic boot module support	dzwdz
	This loads a file from the boot disk into memory. Currently it just gets printed, but it's going to become a real executable soon.
2021-07-17	hacky function for logging pointers	dzwdz

2021-07-17	rename _kernel_end to _bss_end	dzwdz

2021-07-17	multiboot: manually address regions of the kernel	dzwdz
	thanks to this, i can specify the region where the bss is - so GRUB won't place any boot modules there
2021-07-10	abstract away logging	dzwdz
	Now, the kernel only interfaces with the architecture dependent stuff via functions declared in generic.h. I'll write a linter enforcing this soon.
2021-07-10	clean up the GDT initialization code	dzwdz

2021-07-10	allocate the initial stack directly in linker.ld	dzwdz
	IMO it's cleaner this way. I wanted to put it just under 1M, but it turns out that it isn't accessible at boot in QEMU.
2021-07-10	a sensible source structure	dzwdz
	The idea is that src/kernel/ is only allowed to interface with the hardware using whatever's defined in src/arch/generic.h. I'll probably write a small script for checking this later on. This is a giant commit so I've probably fucked something up. It boots fine on Bochs and QEMU, so at least there's that.
2021-07-10	separate the source code from object files; more modular Makefile	dzwdz
