They're mostly the same apart from some x86_64-specific parts.

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.

Kernel: Rename Thread::tss to Thread::regs and add x86_64 support
...
We're using software context switches so calling this struct tss is
somewhat misleading.

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.
