<title>cpufreq: sparc: Don't validate the frequency table twice</title>

The cpufreq core is already validating the CPU frequency table after
calling the -&gt;init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy-&gt;freq_table field directly from the -&gt;init() callback now.

Stop validating the frequency table from sparc driver.

The access to the HBIRD_ESTAR_MODE register in the cpu frequency control
functions must happen on the target CPU. This is achieved by temporarily
setting the affinity of the calling user space thread to the requested CPU
and reset it to the original affinity afterwards.

That's racy vs. CPU hotplug and concurrent affinity settings for that
thread resulting in code executing on the wrong CPU and overwriting the
new affinity setting.

Replace it by a straight forward smp function call.

<title>sched/core: Remove the tsk_cpus_allowed() wrapper</title>

So the original intention of tsk_cpus_allowed() was to 'future-proof'
the field - but it's pretty ineffectual at that, because half of
the code uses -&gt;cpus_allowed directly ...

Also, the wrapper makes the code longer than the original expression!

So just get rid of it. This also shrinks &lt;linux/sched.h&gt; a bit.
