Subject: x86_64: remove STR() macros
From: Glauber de Oliveira Costa <gcosta@xxxxxxxxxx>
Remove the __STR() and STR() macros from x86_64 header files. They seem to
be legacy, and has no more users. Even if there were users, they should
use __stringify() instead.
In fact, there were one third place in which this macro was defined
(ia32_binfmt.c), and used just below. In this file, usage was properly
converted to __stringify()
