Gunnar Beutner	52f9aaa823	Kernel: Use the GS segment for the per-CPU struct ... Right now we're using the FS segment for our per-CPU struct. On x86_64 there's an instruction to switch between a kernel and usermode GS segment (swapgs) which we could use. This patch doesn't update the rest of the code to use swapgs but it prepares for that by using the GS segment instead of the FS segment.	2021-07-02 23:33:17 +02:00
Gunnar Beutner	38fca26f54	Kernel: Add stubs for missing x86_64 functionality ... This adds just enough stubs to make the kernel compile on x86_64. Obviously it won't do anything useful - in fact it won't even attempt to boot because Multiboot doesn't support ELF64 binaries - but it gets those compiler errors out of the way so more progress can be made getting all the missing functionality in place.	2021-06-24 09:27:13 +02:00
