[PATCH v4 13/57] x86/head: remove useless zeroed word

From: Josh Poimboeuf
Date: Thu Aug 18 2016 - 09:16:44 EST


This zeroed word has no apparent purpose, so remove it.

Brian Gerst says:

"FYI the word used to be the SS segment selector for the LSS
instruction, which isn't needed in 64-bit mode."
