[patch 20/24] Add __discard section to x86
Add a __discard sectionto the linker script. Code produced in this section will
not be put in the vmlinux file. This is useful when we have to calculate the
size of an instruction before actually declaring it (for alignment purposes for
instance). This is used by the immediate values.
