X-Git-Tag: v2.6.17-rc1~124
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bc83db4f006fcf9e9502a002b4bd448fc4511d04;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

[PATCH] for_each_possible_cpu: sh

for_each_cpu() actually iterates across all possible CPUs.  We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs.  This is inefficient and
possibly buggy.

We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.

This patch replaces for_each_cpu with for_each_possible_cpu.
