[PATCH 0/4] x86: entry.S cleanup

[Denys Vlasenko]

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.
