2013-04-02cpufreq: drivers: Remove unnecessary assignments of policy-> membersViresh Kumar
Some assignments of policy-> min/max/cur/cpuinfo.min_freq/cpuinfo.max_freq aren't required as part of it is done by cpufreq driver or cpufreq core. Remove them. At some places we merge multiple lines together too. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Rafael J.

2013-04-02cpufreq: Notify all policy->cpus in cpufreq_notify_transition()Viresh Kumar
policy->cpus contains all online cpus that have single shared clock line. And their frequencies are always updated together. Many SMP system's cpufreq drivers take care of this in individual drivers but the best place for this code is in cpufreq core. This patch modifies cpufreq_notify_transition() to notify frequency change for all cpus in policy->cpus and hence updates all users of this API.

2012-01-26cpufreq: Add support for x86 cpuinfo auto loading v4Andi Kleen
This marks all the x86 cpuinfo tables to the CPU specific device drivers, to allow auto loading by udev. This should simplify the distribution startup scripts for this greatly. I didn't add MODULE_DEVICE_IDs to the centrino and p4-clockmod drivers, because those probably shouldn't be auto loaded and the acpi driver be used instead (not fully sure on that, would appreciate feedback) The old nforce drivers autoload based on the PCI ID. ACPI cpufreq is autoloaded in another patch. v3: Autoload gx based on PCI IDs only.
