Subject: [PATCH 07/35] [PATCH 07/36] drivers/cpuidle: Replace __get_cpu_var uses for address calculation
Date: Sun, 17 Aug 2014 12:30:30 -0500 [thread overview]
Message-ID: <20140817173034.022788940@linux.com> (raw)
In-Reply-To: 20140817173023.439660246@linux.com
[-- Attachment #1: 0007-drivers-cpuidle-Replace-__get_cpu_var-uses-for-addre.patch --]
[-- Type: text/plain, Size: 2625 bytes --]
All of these are for address calculation. Replace with
this_cpu_ptr().
