SSE feature: remove inline assembly + don't set reserved bits

[Freax13]

• get rid of inline assembly
• for some reason the previous version also set bits 9 & 10 in Cr0. according to the developer manual bits 5-16 are reserved

Thanks a lot for the pull request!

I'm not sure why we currently set bits 9 and 10 in CR0. From a quick look at the manuals, it seems like you're right that these bits are reserved. Maybe this was a copy&paste error? Perhaps @ethindp who added this code in #77 knows more?

Given that this change only affects the SSE feature and nobody objected it, I'm going to merge it. After all, setting bits 9 and 10 seems like an accident to me.

Thanks for the PR, @Freax13!

I'm honestly not sure myself. The OSDev Wiki listed the code I added to enable SSE -- I didn't write it, though I probably should have (I need ASM practice :)). Perhaps its worth asking on the OSDev Forum?

Thanks for clarifying! I think as long as it still works, setting these bits was likely a copy&paste error.
