+Subject: ASoC: da732x: Mark DC offset control registers volatile
+
+From: Mark Brown <broonie@linaro.org>
+
+commit 75306820248e26d15d84acf4e297b9fb27dd3bb2 upstream.
+
+The driver reads from the DC offset control registers during callibration
+but since the registers are marked as volatile and there is a register
+cache the values will not be read from the hardware after the first reading
+rendering the callibration ineffective.
+
+It appears that the driver was originally written for the ASoC level
+register I/O code but converted to regmap prior to merge and this issue
+was missed during the conversion as the framework level volatile register
+functionality was not being used.

+Subject: ASoC: max98090: sync regcache on entering STANDBY
+
+From: Dylan Reid <dgreid@chromium.org>
+
+commit c42c8922c46d33ed769e99618bdfba06866a0c72 upstream.
+
+Sync regcache when entering STANDBY from OFF.  ON isn't entered with
+OFF as the current state, so the registers were not being re-synced
+after suspend/resume.
+
+The 98088 and 98095 already call regcache_sync from STANDBY.

+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 025c3fa9256d4c54506b7a29dc3befac54f5c68d upstream.
+
+Preset EQ enum of sta32x codec driver declares too many number of
+items and it may lead to the access over the actual array size.
+
+Use SOC_ENUM_SINGLE_DECL() helper and it's automatically fixed.

+

+
+codec->control_data contains a pointer to the regmap struct of the device, not
+to the device private data. Use snd_soc_codec_get_drvdata() instead.

+Subject: ASoC: wm8958-dsp: Fix firmware block loading
+
+From: Lars-Peter Clausen <lars@metafoo.de>
+
+commit 548da08fc1e245faf9b0d7c41ecd8e07984fc332 upstream.
+
+The codec->control_data contains a pointer to the device's regmap struct. But
+wm8994_bulk_write() expects a pointer to the parent wm8998 device.
+
+The issue was introduced in commit d9a7666f ("ASoC: Remove ASoC-specific
+WM8994 I/O code").
+
+Fixes: d9a7666f ("ASoC: Remove ASoC-specific WM8994 I/O code")

+Subject: kvm: x86: fix emulator buffer overflow (CVE-2014-0049)
+
+From: Andrew Honig <ahonig@google.com>
+
+commit a08d3b3b99efd509133946056531cdf8f3a0c09b upstream.
+
+The problem occurs when the guest performs a pusha with the stack
+address pointing to an mmio address (or an invalid guest physical
+address) to start with, but then extending into an ordinary guest
+physical address.  When doing repeated emulated pushes
+emulator_read_write sets mmio_needed to 1 on the first one.  On a
+later push when the stack points to regular memory,
+mmio_nr_fragments is set to 0, but mmio_is_needed is not set to 0.
+
+As a result, KVM exits to userspace, and then returns to
+complete_emulated_mmio.  In complete_emulated_mmio
+vcpu->mmio_cur_fragment is incremented.  The termination condition of
+vcpu->mmio_cur_fragment == vcpu->mmio_nr_fragments is never achieved.
+The code bounces back and fourth to userspace incrementing
+mmio_cur_fragment past it's buffer.  If the guest does nothing else it
+eventually leads to a a crash on a memcpy from invalid memory address.
+
+However if a guest code can cause the vm to be destroyed in another
+vcpu with excellent timing, then kvm_clear_async_pf_completion_queue
+can be used by the guest to control the data that's pointed to by the
+call to cancel_work_item, which can be used to gain execution.
