+
+commit ffe535edb9a9c5b4d5fe03dfa3d89a1495580f1b upstream.
+
+More than one user reports that changing the model from "both" to
+"dmic" makes their Internal Mic work.

+Subject: ALSA: virtuoso: Xonar DS: fix polarity of front output
+
+From: Clemens Ladisch <clemens@ladisch.de>
+
+commit f0e48b6bd4e407459715240cd241ddb6b89bdf81 upstream.
+
+The two DACs for the front output and the surround/center/LFE/back
+outputs are wired up out of phase, so when channels are duplicated,
+their sound can cancel out each other and result in a weaker bass
+response. To fix this, reverse the polarity of the neutron flow to
+the front output.

+Subject: intel idle: Make idle driver more robust
+
+From: Thomas Renninger <trenn@suse.de>
+
+commit 5c2a9f06a9cd7194f884cdc88144866235dec07d upstream.
+
+kvm -cpu host passes the original cpuid info to the guest.
+
+Latest kvm version seem to return true for mwait_leaf cpuid
+function on recent Intel CPUs. But it does not return mwait
+C-states (mwait_substates), instead zero is returned.
+
+While real CPUs seem to always return non-zero values, the intel
+idle driver should not get active in kvm (mwait_substates == 0)
+case and bail out.
+Otherwise a Null pointer exception will happen later when the
+cpuidle subsystem tries to get active:
+[0.984807] BUG: unable to handle kernel NULL pointer dereference at (null)

+Subject: intel_idle: fix API misuse
+
+From: Shaohua Li <shaohua.li@intel.com>
+
+commit 39a74fdedd1c1461d6fb6d330b5266886513c98f upstream.
+
+smp_call_function() only lets all other CPUs execute a specific function,
+while we expect all CPUs do in intel_idle. Without the fix, we could have
+one cpu which has auto_demotion enabled or has no broadcast timer setup.
+Usually we don't see impact because auto demotion just harms power and the
+intel_idle init is called in CPU 0, where boradcast timer delivers
+interrupt, but this still could be a problem.
