Subject: [SPARC]: Remove legacy stuff from cpu_idle().
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7cc1712b8a778c8077048969848857895d242009;p=linux-beck.git

[SPARC]: Remove legacy stuff from cpu_idle().

Currently sparc and sparc64's UP cpu_idle() checks current pid. This
is old time legacy. Now it's paranoia.
