[PATCH 0/4] x86/alternatives: Do NOPs optimization on a temporary buffer

[Borislav Petkov]

From: "Borislav Petkov (AMD)" <bp@xxxxxxxxx>

Hi,

here's a small set which sprang out from my reacting to the fact that
NOPs optimization in the alternatives code needs to happen on
a temporary buffer like the other alternative operations - not in-place
and cause all kinds of fun.

The result is this, which makes the alternatives code simpler and it is
a net win, size-wise:

Constructive feedback is always welcome!

Thx.
