This patch then causes following sparse errors:
./arch/x86/include/asm/local.h:131:16: warning: symbol '__old'
shadows an earlier one
./arch/x86/include/asm/local.h:130:30: originally declared here
This is then visible in all kinds of builds - which makes it hard to
find out actual problems with sparse.
