This is the first part of a bigger patch set I posted last August, then under title of "x86: entry.S optimizations".
I fully rebased that patch set to Linus tree, but currently Linus and -next are diverging a bit in arch/x86/kernel/entry_64.S
To make it easier for mainteiners, I'm splitting the old patch set into more digestible parts.
This is the first set. These four patches apply both to Linus and -next. They do not contain any substantial code changes. Patches 2 and 4 don't result in any actual code changes.
