70395a96bd ASoC: More changes for v5.1
Another batch of changes for ASoC, no big core changes - it's mainly
 small fixes and improvements for individual drivers.
 
  - A big refresh and cleanup of the Samsung drivers, fixing a number of
    issues which allow the driver to be used with a wider range of
    userspaces.
  - Fixes for the Intel drivers to make them more standard so less likely
    to get bitten by core issues.
  - New driver for Cirrus Logic CS35L26.

a0d183c329 ALSA: hda/tegra: property for card name
An optional property "nvidia,model" is introduced for hda to pass custom
name for the sound card. The suffix "-hda" in the name passed is useful
to distinguish between multiple cards available for a platform.
When the property is not specified, default name("tegra-hda") mentioned
in hda driver is used. This property can be added in platform specific
file of the board and card name can relate to the board in use.

d02cac152c ASoC: Updates for v5.1
Lots and lots of new drivers so far, a highlight being the MediaTek
 BTCVSD which is a driver for a Bluetooth radio chip - the first such
 driver we've had upstream.  Hopefully we will soon also see a baseband
 with an upstream driver!
 
  - Support for only powering up channels that are actively being used.
  - Quite a few improvements to simplify the generic card drivers,
    especially the merge of the SCU cards into the main generic drivers.
  - Lots of fixes for probing on Intel systems, trying to rationalize
    things to look more standard from a framework point of view.
  - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
    Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
    BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum
    DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

 "A few updates for x86:

   - Fix an unintended sign extension issue in the fault handling code

   - Rename the new resource control config switch so it's less

   - Avoid setting up EFI info in kexec when the EFI runtime is
     disabled.

   - Fix the microcode version check in the AMD microcode loader so it
     only loads higher version numbers and never downgrades

   - Set EFER.LME in the 32bit trampoline before returning to long mode
     to handle older AMD/KVM behaviour properly.

Make the user prompt more specific. Match the config symbol name.

We used to pass NULL to memory allocators for ISA devices due to
historical reasons.  But we prefer rather a proper device object to be
assigned, so let's fix it by replacing snd_dma_isa_data() call with
card->dev reference, and kill snd_dma_isa_data() definition.

af0c9af1b3 fs/dcache: Track & report number of negative dentries
The current dentry number tracking code doesn't distinguish between
positive & negative dentries.  It just reports the total number of
dentries in the LRU lists.

As excessive number of negative dentries can have an impact on system
performance, it will be wise to track the number of positive and
negative dentries separately.

This patch adds tracking for the total number of negative dentries in
the system LRU lists and reports it in the 5th field in the
/proc/sys/fs/dentry-state file.  The number, however, does not include
negative dentries that are in flight but not in the LRU yet as well as
those in the shrinker lists which are on the way out anyway.

The number of positive dentries in the LRU lists can be roughly found by
subtracting the number of negative dentries from the unused count.

Matthew Wilcox had confirmed that since the introduction of the
dentry_stat structure in 2.1.60, the dummy array was there, probably for
future extension.  They were not replacements of pre-existing fields.
So no sane applications that read the value of /proc/sys/fs/dentry-state
will do dummy thing if the last 2 fields of the sysctl parameter are not
zero.  IOW, it will be safe to use one of the dummy array entry for
negative dentry count.

8950dcd83a iommu/vt-d: Leave scalable mode default off
Commit 765b6a98c1 ("iommu/vt-d: Enumerate the scalable
mode capability") enables VT-d scalable mode if hardware
advertises the capability. As we will bring up different
features and use cases to upstream in different patch
series, it will leave some intermediate kernel versions
which support partial features. Hence, end user might run
into problems when they use such kernels on bare metals
or virtualization environments.

This leaves scalable mode default off and end users could
turn it on with "intel-iommu=sm_on" only when they have
clear ideas about which scalable features are supported
in the kernel.

Turns out this is not such a great idea. Once the SP clock is disabled,
it's not sufficient to just enable in order to bring the SP core back up.

It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.

This reverts commit ed22cee91a.
