sched: Improve scalability via 'CPU buddies', which withstand random perturbations

Traversing an entire package is not only expensive, it also leads to tasks
bouncing all over a partially idle and possible quite large package.  Fix
that up by assigning a 'buddy' CPU to try to motivate.  Each buddy may try
to motivate that one other CPU, if it's busy, tough, it may then try its
SMT sibling, but that's all this optimization is allowed to cost.

Sibling cache buddies are cross-wired to prevent bouncing.

4 socket 40 core + SMT Westmere box, single 30 sec tbench runs, higher is better:

 clients     1       2       4        8       16       32       64      128
 ..........................................................................

A nice increase in performance.

msm: cache_erp: Handle recoverable L1 errors

Some CPU designs may be able to recover from certain types
of L1 instruction cache errors. Rather than panicing
whenever any kind of L1 error is encountered, add an option
to selectively panic on recoverable L1 errors.

msm: mdm: Assert soft_reset_gpio in mdm_power_down_common

In cases where the external modem is powered up very early in the
boot up process, user space application is not loaded as a result
mdm2ap_status is never pulled high. In case where we need to shutdown
the phone for charging we leave the ap2mdm_soft_reset_gpio pulled
high which results in leakage. Assert the ap2mdm_soft-reset_gpio
irrespective of the state of mdm2ap_status gpio.

Asoc: msm: 8064: Set channel as Mono for Incall Music Delivery

For incall music delivery, there is only one share channel is
supported between MDM and APQ. If the media is stereo, afe tries to
open two share channels and causes music playback failure.
Add fixup fucntion to always set the channel as 1 whenever the media
is stereo or mono. And make sure only one share channel is opened.

ASoC: msm: Fix for improper volume ramp up in lpa playback

-A disturbance was heard when switching from one song
to the other, or when the song is paused for greater
than 3 seconds and then resumed
-This was due to the previous value of the track
volume being used in the lpa driver
-This was fixed by setting 0 as the initial volume
