From 22d660ffd0db8d136b122751287d186e869ca474 Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Fri, 10 Oct 2008 01:56:45 +0000 Subject: powerpc/smp: No need to set_need_resched when getting a resched IPI The comment in the code was asking "Do we have to do this?", and according to x86 and s390 the answer is no, the scheduler will do it before calling the arch hook.
