Kernel: Disambiguate instruction size for mov in read_gs_ptr
...
Previously we allowed using immediate values here which is ambiguous
as to which specific mov instruction the compiler should choose.

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.
